This Cocker Spaniel feeding chart shows how much to feed at every age, from an 8 week old puppy to a senior dog. Cockers are prone to weight gain and pancreatitis, so the calculator helps you find a measured amount instead of guessing.

Cocker Spaniel at a glance
Enter your dog's weight and age. Puppies also get an estimate of their adult weight. Open "Your food" to add the numbers from your bag, mix in wet food or work out a monthly cost. Then fine tune using body condition, since every dog and every food is a little different.
Life stage: adult
Activity, goal and neuter status apply from 12 months. Growing dogs are fed by age and weight.
Dry food label
If the bag lists kcal per kg as well, grams per cup = kcal per cup ÷ kcal per kg × 1,000.
Mixed feeding
Use the kcal per can, tray or pouch printed on the wet food label.
Cost
Exact amount: 1.75 cups
Based on a dry food with 456 kcal per cup. If you give treats, take their calories out of the daily total, and recheck body condition every two to four weeks.
Resting energy (RER) is 70 times body weight in kilograms raised to the power of 0.75, then multiplied by a factor for life stage and activity. The Merck Veterinary Manual uses 3 times RER for puppies under 4 months and 2 times RER after that. The Pet Nutrition Alliance lists 2 to 3 times RER for growth, 1.8 for an intact adult, 1.6 for a spayed or neutered adult, 1.2 to 1.4 for an overweight prone or inactive adult and 1.0 for weight loss, and stresses that individual dogs can vary by as much as 50 percent from these estimates.
How this page applies them: 3.0 under 4 months and 2.0 from 4 to 12 months, the Merck values. Adults use 1.8 for moderate activity, 1.4 for low activity (the top of the Pet Nutrition Alliance range for overweight prone or inactive dogs) and 2.2 for high activity, which is our own estimate for a working gundog. Seniors use 1.2, 1.4 and 1.6, also our own estimates. Spayed or neutered adults and seniors get about 11 percent less, the same gap as between 1.8 and 1.6.
Calories are divided by your food's energy density, 456 kcal per cup and 120 g per cup unless you enter your own. Treats are capped at 10 percent of the daily total and water is estimated at about one ounce per pound. The adult weight estimate divides your puppy's weight by the typical share of adult weight for its age from the growth table below, plus or minus 12 percent.
The fastest way to see how much a Cocker Spaniel eats at each stage. Ranges run from a smaller female to a larger male of the same age, using a dry food with 456 kcal per cup.
| Age | Typical weight | Meals per day | Cups per day | Grams per day | kcal per day |
|---|---|---|---|---|---|
| 8 to 10 weeks | 5 to 7.5 lb | 4 | ⅞ to 1⅛ | 105 to 140 g | 390 to 530 |
| 3 to 4 months | 8 to 16.5 lb | 4 | 1¼ to 2⅛ | 145 to 250 g | 550 to 950 |
| 4 to 6 months | 11 to 22.5 lb | 3 | 1 to 1¾ | 125 to 210 g | 470 to 800 |
| 6 to 9 months | 15 to 27.5 lb | 3 | 1¼ to 2 | 155 to 245 g | 590 to 930 |
| 9 to 12 months | 18.5 to 30 lb | 3 | 1½ to 2⅛ | 180 to 260 g | 690 to 990 |
| Adult, moderate activity | 20 to 30 lb | 2 | 1½ to 2 | 175 to 235 g | 660 to 890 |
The adult row covers intact dogs. Spayed or neutered adults need about 11 percent less, shown in the adult chart below.
Four things decide the daily number: current weight, life stage, activity level and neuter status. The Cocker Spaniel is the smallest dog in the AKC Sporting Group, and the American Kennel Club lists males at 25 to 30 pounds and females at 20 to 25 pounds. The English Cocker Spaniel is a separate, slightly larger breed at 26 to 34 pounds.
Cockers love food and tend to gain weight once they are neutered and less active. They also have a higher than average risk of pancreatitis, so the quality of the calories matters as much as the quantity: a measured complete food, and very few fatty extras.
Cocker Spaniel puppies of the same age can differ by several pounds. Feeding by current weight is more accurate than feeding by birthday. Find your puppy's weight in the left column, then read across to its age.
| Puppy weight | 2 to 4 months | 4 to 12 months |
|---|---|---|
| 5 lb (2.3 kg) | ⅞ cup, 105 g | not typical |
| 7 lb (3.2 kg) | 1⅛ cups, 130 g | not typical |
| 9 lb (4.1 kg) | 1⅜ cups, 160 g | not typical |
| 11 lb (5 kg) | 1½ cups, 185 g | 1 cup, 125 g |
| 13 lb (5.9 kg) | 1¾ cups, 210 g | 1⅛ cups, 140 g |
| 15 lb (6.8 kg) | 1⅞ cups, 230 g | 1¼ cups, 155 g |
| 17 lb (7.7 kg) | not typical | 1⅜ cups, 170 g |
| 20 lb (9.1 kg) | not typical | 1⅝ cups, 190 g |
| 23 lb (10.4 kg) | not typical | 1¾ cups, 215 g |
| 26 lb (11.8 kg) | not typical | 2 cups, 235 g |
| 30 lb (13.6 kg) | not typical | 2⅛ cups, 260 g |
Daily totals for a food with 456 kcal per cup, to the nearest eighth of a cup. Split into four meals before 4 months, three meals until 12 months, then two.
Energy needs per pound are at their lifetime peak. Four small meals of a complete puppy food work best, and weighing the puppy every week or two shows whether the amount is right.
Growth slows and energy needs per pound fall, so the calculator drops from 3.0 to 2.0 times RER. Move to three meals. This is the age when begging habits form, and a Cocker that learns that the table pays off rarely forgets it.
Most Cockers are close to adult size by their first birthday. The amount in the bowl should level off even if appetite does not. Switch to adult food around 12 months, and keep the waist visible as growth finishes.
Use this to check whether your puppy is on track. Shaded bands show the typical range for males and females, and the line shows the middle of each range. The calculator uses these same figures to estimate your puppy's adult weight.
| Age | Male weight | Female weight | Share of adult weight |
|---|---|---|---|
| 2 months | 6 to 7.5 lb | 5 to 6 lb | About 25% |
| 3 months | 10 to 12 lb | 8 to 10 lb | About 40% |
| 4 months | 14 to 16.5 lb | 11 to 14 lb | About 55% |
| 6 months | 19 to 22.5 lb | 15 to 19 lb | About 75% |
| 9 months | 23 to 27.5 lb | 18.5 to 23 lb | About 92% |
| 12 months | 25 to 30 lb | 20 to 25 lb | Adult |
Adult ranges follow the AKC breed profile for the American Cocker Spaniel. No growth study exists for the breed, and published monthly charts come from breeders and disagree, so these figures are our own estimate from the typical growth pattern of small to medium dogs (Salt et al., 2017). The parents' size is a useful guide to your puppy's likely adult size.
A complete puppy food covers everything a growing Cocker needs. A moderate fat recipe is a sensible habit to start with for a breed prone to pancreatitis.
The AAFCO floor for puppy food. Adult maintenance food needs at least 18%. Most quality puppy formulas run a few points higher.
Adults need at least 5.5%. Fat is the most calorie dense nutrient, so a rich puppy food makes overfeeding easier.
AAFCO's growth range for all sizes, with a calcium to phosphorus ratio between 1:1 and 2:1. A complete puppy food already gets this right.
These figures come from the AAFCO Dog Food Nutrient Profiles (published in the AAFCO Official Publication). They are floors and ceilings, not targets, and any food labelled "complete and balanced" for growth or for all life stages already meets them.
Do not add calcium or other supplements to a complete puppy food, and avoid rich toppers. If you are comparing labels, our guide to puppy food brands is a good place to start.
Feed by current weight and activity, then adjust every few weeks based on body condition. Most pet Cockers fit the moderate, low or neutered column. The 33 lb row is there for English Cockers and larger dogs.
| Weight | Low activity | Moderate activity | High activity | Neutered, moderate |
|---|---|---|---|---|
| 18 lb (8.2 kg) | 1 cup | 1⅜ cups | 1⅝ cups | 1⅛ cups |
| 20 lb (9.1 kg) | 1⅛ cups | 1½ cups | 1¾ cups | 1¼ cups |
| 22 lb (10 kg) | 1¼ cups | 1½ cups | 1⅞ cups | 1⅜ cups |
| 24 lb (10.9 kg) | 1¼ cups | 1⅝ cups | 2 cups | 1½ cups |
| 26 lb (11.8 kg) | 1⅜ cups | 1¾ cups | 2⅛ cups | 1½ cups |
| 28 lb (12.7 kg) | 1½ cups | 1⅞ cups | 2¼ cups | 1⅝ cups |
| 30 lb (13.6 kg) | 1½ cups | 2 cups | 2⅜ cups | 1¾ cups |
| 33 lb (15 kg) | 1⅝ cups | 2⅛ cups | 2⅝ cups | 1⅞ cups |
Daily totals for a food with 456 kcal per cup, split into two meals. Low, moderate and high use 1.4, 1.8 and 2.2 times RER for an intact dog. Neutered moderate uses 1.6.
Cups change from brand to brand. Calories do not. If your food is denser or lighter than 456 kcal per cup, work from these numbers and divide by the kcal per cup printed on your bag, or enter that number in the calculator.
| Body weight | Resting energy (RER) | Intact adult (1.8) | Neutered adult (1.6) | Weight loss (1.0) |
|---|---|---|---|---|
| 8 kg (18 lb) | 333 kcal | 600 kcal | 530 kcal | 330 kcal |
| 9 kg (20 lb) | 364 kcal | 650 kcal | 580 kcal | 360 kcal |
| 10 kg (22 lb) | 394 kcal | 710 kcal | 630 kcal | 390 kcal |
| 11 kg (24 lb) | 423 kcal | 760 kcal | 680 kcal | 420 kcal |
| 12 kg (26 lb) | 451 kcal | 810 kcal | 720 kcal | 450 kcal |
| 13 kg (29 lb) | 479 kcal | 860 kcal | 770 kcal | 480 kcal |
| 14 kg (31 lb) | 507 kcal | 910 kcal | 810 kcal | 510 kcal |
Weight loss calories should be calculated from the target weight, not the current one. The calculator does this for you.
Most pet Cockers are neutered and moderately active. For them the neutered column is usually the right starting point. If your dog still gains weight, drop to the low column or use the calculator's weight loss mode.
The AKC puts Cocker Spaniel life expectancy at 10 to 14 years. Most slow down after age 8 and need fewer calories, even if their appetite has not changed.
| Weight | Low activity | Moderate activity | Neutered, moderate | Meals per day |
|---|---|---|---|---|
| 18 lb (8.2 kg) | ⅞ cup | 1 cup | ⅞ cup | 2 |
| 20 lb (9.1 kg) | 1 cup | 1⅛ cups | 1 cup | 2 |
| 22 lb (10 kg) | 1 cup | 1¼ cups | 1⅛ cups | 2 |
| 24 lb (10.9 kg) | 1⅛ cups | 1¼ cups | 1⅛ cups | 2 |
| 26 lb (11.8 kg) | 1⅛ cups | 1⅜ cups | 1¼ cups | 2 |
| 28 lb (12.7 kg) | 1¼ cups | 1½ cups | 1¼ cups | 2 |
| 30 lb (13.6 kg) | 1⅜ cups | 1½ cups | 1⅜ cups | 2 |
Daily totals for a food with 456 kcal per cup. Low and moderate use 1.2 and 1.4 times RER for an intact senior. Neutered moderate uses about 1.24.
Four meals until about 4 months, three until about 12 months, then two for life. Here is what that looks like in a normal day.
Exact times do not matter. Consistency does. For a Cocker, fixed meal times cut down on begging, and two moderate meals are easier on the digestive system than one large, rich one. Long ears also dip into the bowl, so a narrow, deep "spaniel bowl" keeps them out of the food.
Pancreatitis is inflammation of the pancreas. It can be mild or life threatening, and Cocker Spaniels are among the breeds with a higher risk.
In a post mortem study of 200 first opinion dogs, Cocker Spaniels had an increased risk of acute and chronic pancreatitis combined.
A 2024 study describes chronic pancreatitis as a common disease in English Cocker Spaniels, with signs that are often vague, such as reduced appetite, vomiting and weight loss.
VCA notes that an episode may be triggered in some dogs by a fatty meal. Table scraps, bacon, sausages, poultry skin and gravy are the usual suspects.
Know the signs. Repeated vomiting, a painful or hunched belly, refusing food and lethargy need a vet the same day. A dog that has had pancreatitis usually needs a low fat diet chosen by the vet for life.
For a healthy Cocker, there is no need for a prescription low fat food. A complete adult food with a moderate fat level, measured portions and a strict no scraps rule are the practical steps. If you are choosing between foods, compare the fat percentage on a dry matter basis, and ask your vet which range suits your dog.
Three other Cocker Spaniel health issues connect to what and how you feed.
In the Multicenter Spaniel Trial, American Cocker Spaniels with dilated cardiomyopathy and low taurine responded to taurine and carnitine supplements, and most could stop their heart medication. Testing and dosing belong with your vet.
VCA names Cocker Spaniels among the floppy eared breeds prone to ear infections, and notes that ear infections occur in 65 to 80 percent of dogs with food allergies.
In a study of 10,313 English Cockers in UK vet practices, periodontal disease was the most common diagnosis at about 21 percent. Daily brushing does more than any food.
The same study recorded obesity in about 10 percent of English Cockers, and a UK study of more than 22,000 dogs found Cocker Spaniels had higher odds of being overweight than crossbreeds.
Repeated ear infections are often the first sign of an allergy, and diet is only one possible cause. If your Cocker has itchy ears and skin all year, ask your vet about an elimination diet trial before switching foods again and again.
The charts give a starting point. Your dog's body tells you whether it is right. The WSAVA 9 point body condition scale puts the ideal at 4 to 5 out of 9.

Ribs, spine and hip bones are easy to see. Muscle loss may be visible. Feed about 10 percent more and recheck in two weeks.
View from above
Ribs are easy to feel under a thin layer of fat. From above you see a waist behind the ribs, and from the side the belly tucks up.
View from above
Ribs are hard to feel, there is no clear waist, and fat builds up over the back and base of the tail. Cut food by about 10 percent and trim treats.
A Cocker's feathered coat hides more than you might think, especially along the chest and belly. Use your hands, not your eyes: press lightly along the side of the chest and feel for the waist behind the ribs.
Weight loss is a common goal for adult Cockers, especially after neutering, and it also lowers the fat load that matters for the pancreas.
Start with an honest count of everything your Cocker eats, including treats, chews and table scraps. Staying lean pays off over a lifetime: in a 14 year feeding study, dogs fed 25 percent less than their littermates lived a median of 1.8 years longer.
Swap part of the kibble for low calorie extras like plain green beans if your dog struggles with smaller portions, and use scent games and retrieves to burn energy. Very large cuts should only be made with a vet, since dogs fed too little can lose muscle along with fat.
A healthy Cocker Spaniel on a complete and balanced food does not need anything added. Fish oil in particular should be discussed with your vet first, because it adds fat.
EPA and DHA from fish oil have the strongest research behind them for stiff joints. In a controlled study of dogs with osteoarthritis, those fed a food high in fish oil omega-3s bore more weight on their sore legs than dogs on a control food.
Widely used and generally well tolerated, but studies disagree on how much they help. Worth a trial for an older dog with a vet's input, not something a young healthy dog needs.
These are part of treatment for Cockers diagnosed with taurine deficient heart disease. For a healthy dog on a complete food, there is no need to add them without your vet's advice.
Everything your Cocker Spaniel eats or drinks counts, not just the main meals.
Plan on about one ounce per pound of body weight a day, roughly 20 to 30 ounces (0.6 to 0.9 liters) for an adult. Needs rise in warm weather, after exercise and on a dry kibble diet. Keep water available all day, ideally in a bowl the ears do not trail in.
Keep treats under 10 percent of daily calories. For a Cocker eating 800 kcal a day, that is about 80 kcal. Choose low fat healthy dog treats, break them into small pieces for training, or use part of the daily kibble as rewards.
Small habits that make any feeding chart work better.
Worth doing
Worth avoiding
The daily calorie target stays the same whatever the format. What changes is volume, cost, prep and how easy it is to keep the nutrients balanced.
| Format | Typical energy | Prep | Best for | Watch out for |
|---|---|---|---|---|
| Dry kibble | 350 to 500 kcal per cup | None | Easy portion control, lowest cost | Large calorie differences between brands |
| Wet or canned | Much lower per gram | None | Picky eaters, extra moisture | Often higher in fat per calorie |
| Raw | Varies with fat content | Thawing, strict hygiene | Owners willing to follow a complete recipe | Bacteria, nutrient balance |
| Fresh or home cooked | Varies by recipe | High | Food sensitivities, full ingredient control | Unbalanced homemade recipes |
For raw diets, the FDA's testing of commercial raw pet foods found Salmonella and Listeria in a meaningful share of samples, a risk for the people in the house as well as the dog. Home cooked diets are safe from that angle but easily drift out of balance on calcium and other minerals. Whichever format you use, pick a recipe that is complete and balanced for your dog's life stage, or one written by a board certified veterinary nutritionist.
Whatever the format, check the fat content. For a Cocker, a raw or home cooked diet that is high in fat is a bigger risk than for most breeds, so any home recipe should come from a veterinary nutritionist.
Itchy skin, ear infections and upset stomachs are common reasons Cocker owners change food. With this breed, a fatty treat or a raided bin is often the cause of a stomach upset, so rule that out first.
Itching all year round, especially the paws, face, ears and rear end, repeated ear infections, and sometimes soft stool or more frequent bowel movements. Seasonal itching points more toward environmental allergies.
A review of published cases found beef, dairy, chicken and wheat were the most commonly reported food allergens in dogs. The trigger is almost always a protein, so "grain free" alone rarely solves it.
Blood, hair and saliva tests sold for food allergies are not reliable, and vets generally do not use them to diagnose one. During the trial, enter the new food's kcal per cup in the calculator, since therapeutic diets often differ a lot from regular kibble.
For a sensitive stomach without allergy signs, the fix is usually simpler: a gradual food change, consistent meal times, fewer fatty extras and gentle treats. Vomiting with a painful belly, or diarrhea lasting more than a day or two, needs a vet, since it can be pancreatitis.
Whether you are moving from puppy to adult food or changing brands, go slowly over 7 to 10 days.
Recalculate portions when the switch is done. A new food almost never has the same kcal per cup as the old one, and feeding the same number of cups can quietly add or remove a lot of calories. If stools go soft at any step, stay at that ratio for a few extra days before moving on. For a second opinion on the new portion, our dog food calculator works out daily amounts in cups, grams and ounces for any breed.
If you are switching because of pancreatitis or ear problems, follow your vet's timeline, which may be faster or slower than this one.
The charts on this page assume a healthy dog. These situations need a different plan.
Energy needs stay fairly stable until the last third of pregnancy, then rise to about 1.6 to 2 times resting energy. At peak lactation, three to four weeks after whelping, the Pet Nutrition Alliance puts needs at 2 to 6 times resting energy, so a mother with a large litter can need more than twice her normal amount. Many breeders switch to a puppy or all life stages food in late pregnancy.
A Cocker that has had pancreatitis needs the low fat diet and feeding plan its vet recommends. The standard chart amounts do not apply to prescription foods with different calories per cup.
Heart disease, hypothyroidism, chronic ear disease, kidney disease and food allergies all change what and how much a dog should eat. The diet should come from your vet, and the chart becomes background information.
A severely underweight dog needs a gradual refeeding plan from a vet. Jumping straight to a full portion can cause serious problems.
Feeding a different breed as well? Compare with our Cavalier King Charles Spaniel feeding chart, Beagle feeding chart, Miniature Schnauzer feeding chart and Golden Retriever feeding chart, or use the general dog calorie calculator for mixed breeds.
The amounts on this page are general estimates meant as a starting point, not a substitute for veterinary advice. Every dog's metabolism, health and food are different, so confirm portions with your vet, especially for puppies, seniors, pregnant females and dogs with health conditions.
