How dog food helped my Cocker Spaniel lose weight

What’s the Ideal Cocker Spaniel Weight? Growth Guide

How much is too much when it comes to Cocker Spaniel weight? Cockers are notorious foodies, always looking to their dog mom or dad for a snack or treat. Some people call Cockers “bottomless pits” because they love to eat and are often food motivated.

Because the American Cocker Spaniel loves food so much, they can very easily become overweight, which leads to all sorts of health problems. Like people, each dog is different and that goes for Cocker Spaniels. American Cockers tend to be a bit smaller than English Cocker Spaniels, so keep that in mind as you aim for your dog’s healthy weight.

According to the American Kennel Club, the Cocker Spaniel is the smallest of the Sporting breed and stands around 14 to 15 inches. The breed “standard” calls for them to be big enough to be sporty yet compact enough to be portable. So what’s the best weight for your Cocker Spaniel? Here’s everything you need to know and some fun facts and Cocker care tips along the way.

What Is the Ideal Cocker Spaniel Weight?

The ideal weight of a Cocker Spaniel depends on the dog’s body size. In researching this piece, I talked to several reputable breeders. According to long-time Cocker Spaniel breeder-owner-handler, Marlene Ness, “On average, an adult female American Cocker Spaniel should weigh between 18 and 22 pounds, while a male hovers around the 25-pound mark.”

Not all Cockers will fit this weight range, and often as dogs get older, they will either gain or lose weight. If your dog starts gaining or losing weight suddenly, always report this to your veterinarian.

“Most certainly, a purebred Cocker Spaniel should never weigh between 40 and 50 pounds,” Ness told me.

There’s a breed standard, which is what the American Spaniel Club dictates, for Cocker Spaniels. Then there is the ideal weight that consider various factors for your Cocker Spaniel. Is your dog getting daily exercise? A couch potato? Have any medical conditions? Being overfed? Not walked enough?

I’ve been a Cocker Spaniel mom for over 30 years. I’ve encountered thousands of Cocker Spaniels. The average Cocker Spaniel housepet weight ranges anywhere between 18 pounds and 27 pounds for females and 23 to 34 pounds for males.

Some Cockers do not meet the breed standard and might be taller, so they weigh more. Some Cockers are overweight. Others are very obese.

In The Cocker Spaniel Handbook, Caroline Colie, Ph.D., says most fat-looking Cockers are fat because they simply eat more calories than they burn. These dogs need to lose weight. We’ll discuss how to help your Cocker Spaniel lose weight shortly.   

Should I Follow Feeding Instructions On The Dog Food Packaging?

Many times, pet parents believe they are doing right by their dogs in following the feeding instructions on a bag or can of dog food. This can lead to weight gain really fast, and I’ve seen this firsthand.

I’ve worked in the pet industry for nearly 15 years, and I do not recommend most feeding instructions on dog food packages. Dog food labels generally do not include calorie information, so you will need to calculate them yourself. It may seem tricky, but it’s pretty easy to figure out how much food your average non-working dog needs to eat daily.

Each Cocker Spaniel is different. Some Cockers compete in agility and others live a more couch potato life. All dogs should receive some form of physical and mental stimulation each day.

Your dog’s veterinarian or a pet nutritionist can help determine the specific number of calories your dog needs based on many factors. However, if you want a general formula to determine your Cocker’s average daily caloric intake, here’s how:

The Pet Nutrition Alliance put together a calorie calculator for dogs. You’ll need to know your dog’s current body condition score, which you can determine in the chart below:

Plugin your dog’s weight, if he is spayed or neutered, and a few other fields. You’ll be given an estimated ideal weight, if he is overweight and by what percentage, and how many estimated daily calories he should receive.

Insider Tip: I’ve spoken to many pet food representatives over the years who admit their feeding instructions aren’t ideal for many dogs. They are trying to sell pet food, so the more you feed your dog, the more they sell. The food might be awesome and considered a balanced diet, but use caution in feeding amounts.

When Do Cocker Spaniels Stop Growing?

Cocker Spaniels are generally fully grown between nine and 12 months of age. Most Cockers will reach full maturity between 18 and 24 months even though their bodies stop growing.

Like people, Cocker Spaniels develop at different rates. One 8-month-old Cocker Spaniel puppy weighs 16 pounds while another weighs 21 pounds. Dogs develop at their own pace and there are many factors that contribute to development and weight gain.

Female Cocker Spaniels are smaller than their male American counterparts, both English and American.

How Do I Know If My Cocker Spaniel is Underweight?

Most people talk about overweight dogs, but some Cocker Spaniels can be underweight. A dog mom once wrote me in complete distress. Her veterinarian informed her that her female Cocker was underweight.

“I had no idea my dog didn’t weigh enough. Am I a bad person?” she asked.

No, she isn’t a bad person. She had no idea. If your dog is underweight, talk to your veterinarian about any underlying health conditions. She might need more calories. If she’s a high-performing dog, she could be burning more calories than she is taking in.

What is the Average Cocker Spaniel Height?

According to the American Spaniel Club, the official breed standard lists the ideal height for female American Cocker Spaniels at 14 inches versus 15 inches for males. Remember, this is the standard for conformation. Female English Cockers are around 15 to 16 inches, with English males around 16 to 17 inches.

From a dog show standpoint, a male whose height is less than 14-1/2 inches and a female whose height is less than 13-1/2 inches are penalized in the dog show ring.

From a house dog standpoint, Cockers range in height from 14 to 16 inches, although I’ve seen many taller Cockers who are not in the show ring.

Cocker Spaniel Puppy Weight Chart

The following weight chart represents the average weight by month for Cocker Spaniel puppies. If your Cocker is not gaining weight or appears to be gaining weight too fast, seek veterinary attention.

According to Woelwater Spaniels, all Cockers attain their maximum height until they reach 12 months of age, but their body muscles continue to develop until they are two years old. This is their estimation of the average Cocker Spaniel puppy’s weight progress in their first year:

1 MONTH2.13 LBS (1.3 KG)
2 MONTHS6.10 LBS (3.0 KG)
3 MONTHS14.5 LBS (6.5 KG)
4 MONTHS17.10 LBS (8.0 KG)
5 MONTHS22 LBS (10 KG)
6 MONTHS 25.5 LBS (11.5 KG)
7 MONTHS27.8 LBS (12.5 KG)
8 MONTHS29.3 LBS (13.25 KG)
9 MONTHS29.12 LBS (13.5 KG)
10 MONTHS29.15 LBS (13.6 KG)
11 MONTHS30.3 LBS (13.7 KG)

At 6 months of age, the average female Cocker Spaniel puppy weighs between 20 pounds for smaller-statured Cockers and 25 pounds 6 ounces for larger-statured Cockers. When she reaches a year old, most female Cockers are between 26 pounds and 32 pounds for larger-statured dogs.

At 6 months of age, the average male Cocker Spaniel puppy weighs between 22 pounds for smaller-statured Cockers and 26 pounds 4 ounces for larger-statured Cockers. When he reaches a year old, most female Cockers are between 28 pounds and 34 pounds for larger-statured dogs.

Weight fluctuations are normal depending on the Cocker’s size and gender, American or English, feedings, exercise, and veterinary recommendations. I highly recommend you monitor your dog’s growth and weight with a Cocker Spaniel growth chart you can track in the DogMinder for under $10 bucks.

Do All Adult Cockers Weigh the Same Amount?

No, all adult Cocker Spaniels do not weigh the same amount. In my Club Cocker: Wigglebutts Worldwide, someone recently posed this question:

Is 50 pounds too much for my male Cocker Spaniel?

The answer is yes, that is way too much. This particular dog takes steroids for an immune system disease he battled called IMHA. Steroids do not make a dog overweight; they do, however, make a dog hungry among other things.

The Association for Pet Obesity Prevention reveals that 57.9% of cats and 52.7% of dogs are overweight or obese. That’s astounding. Many veterinarians don’t approach this sensitive topic with their clients because they fear repercussions in the form of losing a client.

Here are a few comments from Cocker Spaniel owners I interviewed for this piece:

Kim K says, “I’ve always had to watch Poppy’s weight because of her disk disease. At her heaviest, at age three, she was 24 lbs. She’s been at 470 calories a day for many years and has been 21 to 22 pounds.

She has had muscle loss since she’s 13 and I’ve had to lower her phosphorus to protect her kidneys. I’ve had to lower her fat intake too. Protein 42%, fat 23%, and carbs 35% of calories. She has more carbs than a typical raw fed dog to make up for her phosphorus and fat to be reduced.”

Nicole T. says, “Mine are all in a healthy weight. Beryl and Brooke are about 18 pounds, Aurora 20 pounds, Amelia is 21 pounds, and Chadwick is 25.5 pounds. I am a raw feeder, so they eat really well. Nobody is overweight at all. They are on the leaner side. They love their food, nobody is picky at all.”

Carol B (me) says, “Both my female and male American Cocker Spaniels were pretty much on target with weight gain as indicated in the puppy weight chart above. At 3-1/2 months, my female was about 12 pounds and my first male was 13.4 pounds.”

How Do I Know If My Cocker Spaniel is Overweight?

First, feel around your Cocker’s ribs and spine; you should be able to locate both, with only a thin layer of fat separating the skin from bones. Your veterinarian can show you how to do this so you can ensure your Cocker gets proper care and is at the right weight.

If you are unable to find the ribcage, your dog is likely overweight. Viewing your Cocker Spaniel from above, you should be able to see a moderate narrowing at the waist just past his ribcage.

A large and drooping abdomen is another sign that your pooch is overweight. A bulging line from the ribcage to the hips may indicate an overweight dog. Ask your veterinarian to evaluate your dog’s size at every visit.

Once your canine has reached maturity, ask for his optimal weight. The following chart can help:

How Can I Help My Cocker Spaniel Lose Weight?

I helped my Cocker Spaniel lose weight. It’s a longer process for a dog to lose weight because they have to take it off slower than a person.

My veterinarian advises to reduce the amount of food and treats you feed gradually rather than making drastic changes all at once. If you cut back on the amount of food too dramatically, it will abruptly change your dog’s metabolism.

This makes it more difficult to lose weight and easier to gain it back. Keep in mind that slow and steady weight loss is more likely to result in long-term results and success.

According to the experts at Whole Dog Journal, weigh your dog frequently, especially when first starting a weight-loss program. Aim for weight loss of 3 to 5 percent of body weight per month or one percent per week. A 50-pound dog should lose about half a pound per week or 2 pounds per month.

When I talked to our dog’s veterinarian about weight loss for my second Cocker Spaniel (Dexter), she told me I could cut how much I feed him each meal by 20 percent. I also changed his food formula but stayed in Dr. Harvey’s family of dog foods.

Weigh your dog. You can stand on the scale for your weight, hold your Cocker and then subtract your weight. It is best to do this in the morning before your dog eats or drinks but after she pees and poops.

Determine if your dog is overweight and how many pounds he or she needs to lose. Record the data in our DogMinder Canine Health and Wellness Journal.

Here’s how I helped my Cocker Spaniel lose weight.

Are Cocker Spaniels Prone To Weight Gain?

I agree with Dr. Coile who says two of your Cocker’s favorite things are eating and exercising. Yes, Cockers are foodies and because of this, they may gain weight. If your dog gets too much food or treats, it will likely show up on the scale.

Some health disorders, such as heart disease, Cushing’s disease, early-stage diabetes, and hypothyroidism can all make a dog appear to be overweight. A dog with a large abdomen should always be a warning, as this could indicate a health crisis. Dogs or puppies with a bloated belly may be affected by worms.

How To Maintain A Senior Cocker’s Weight

As a Cocker Spaniel ages, he may lose muscle mass. If your senior Cocker is overweight, it may be harder to lose those extra pounds. A few things most experts recommend to help a senior Cocker Spaniel drop extra pounds include:

  1. Increase her protein intake
  2. Replace carbs with fats safely
  3. Switch to lower calorie or less frequent treats
  4. Try a treat ball that you can fill with treats
  5. Slower, shorter, more frequent walks
  6. Exercise safely indoors. Here are 101 things you can do with your dog indoors. Many of them apply to senior dogs.
  7. Consider adding fiber to your dog’s diet.

Pro Tip: It’s a good idea for dog owners to check their Cocker’s weight weekly. Stand on your scale, get the weight, and hold your dog still in your arms. Subtract your weight and log the dog’s weight into the DogMinder. This is the best way to see weight changes at a glance. Ask your veterinarian about the minimum and maximum weight range for your dog.

Kidney disease is common in aging dogs and may lead to weight loss. Always work in tandem with your veterinarian to determine why your dog is gaining or losing weight at any stage of her life.

  1. Oscar is 3-he will be 4 in November. He is a BIG cocker, very athletic, purebred American Cocker but looks English. This boy is 37 pounds and not an ounce of fat on him. He is fast in play and loves a good bird chase. He is the biggest cocker that I have ever had. My others were 21 to 28 pounds, which is more the breed standard.
