Cocker Spaniel Weight: What's Ideal?

What's the ideal Cocker Spaniel weight?

Your pet's health, age, sex and size of his frame can influence on your dog's weight. Bearing this in mind, you can work out much your new Cocker Spaniel puppy should weigh now and what he should weigh when he's all grown up!

What Is The Ideal Cocker Spaniel Weight?

Cockers are gluttons, so owners need to keep a beady eye on their dog's weight. My Cocker isn't motivated by toys, but boy, I can get him to do pretty much anything for a treat!

Then there's what I call 'the Cocker cuteness factor'. Because they're so adorable-looking, friends, family and visitors often sneak him the odd treat.

And as well-intentioned as this often is, it's not good for your Cocker's waistline! I've set out below some idea of your Cocker Spaniel's weight during certain stages in his life.

However, when looking at this chart, you'll need to consider other factors, such as his breed (American, English or working Cocker), size, age, sex, and your dog's health and lifestyle.

The Ideal English Cocker Spaniel Weight and Height

The English Cocker Spaniel Weight

Their recommended weight falls between 12 and 14.5 kg, and because the bitches are usually smaller than the males, they tend to weigh a little less.

Confusing matters, the American Kennel Club suggests slightly different sizes and weights for the English breed. They indicate that male and female dogs should be between 38 and 43 cm tall at the shoulder and weigh 11.75 and 15.5 kg, respectively.

And for males, height at the withers ought to be between 40.5 and 43 cm and for the females, 38 and 40.5 cm.

The American Kennel Club also suggests that the most desirable weight for an English Cocker Spaniel male is between 12.5 and 15.5 kg. Their recommendations for the female Cockers are between 11.75 and 14.5 kg.

The English Cocker Spaniel Height

The ideal height for an English Cocker Spaniel male is between 39 cm and 41 cm; (15-16"), and for the bitch, it should be between 38 cm and 39 cm (15-15.5") tall.

The Ideal American Cocker Spaniel Weight and Height

American Cocker Spaniel Weight

Generally, an adult American male dog should weigh between 11 and 13 kg (24 and 28 lbs), and adult females usually weigh slightly less because they're smaller.

If you'd like more about the American breed standard, you'll find more information here.

American Cocker Spaniel Height

The American Cocker Spaniel is slightly smaller than its English cousin, and in both breeds, the females are somewhat smaller than the males.

Generally, the ideal height for male and female American Cockers range between 35.5 cm (14") and 38 cm (15") at the shoulder, but an allowance of plus or minus 1.26 cm (0.5") is acceptable for both sexes.

Specifically, the ideal height for the male dog is between 37 and 38 cm, and for bitches it ranges between 35.5 and 37 cm.

Cocker Spaniel Weight: Puppy To Adult Weight

Inexperienced, new puppy owners often worry about their pups being too thin or too fat, so it's no surprise that I'm frequently asked questions about the ideal Cocker Spaniel weight.

Questions such as: 

"I think my dog is overweight. He's five years old and fairly active; what's his ideal weight?"

"What is the average weight of dogs?"

"What is the Cocker Spaniel average weight?"

The chart below should give you a general idea of how much your puppy should weigh, but I must stress that this information is for guidance purposes only.

Don't worry if your puppy is a little outside of the guidelines for his age; not all dogs and puppies are the same (just like we humans!).

If you've any real concerns about your puppy's weight or development, please speak to your vet or veterinary nurse for advice.

Cocker Spaniel Weight and Age

Both English and American Cocker Spaniels are prone to obesity, especially as they get older. Hence, it's essential to ensure that they get plenty of exercise (although dogs may no longer be as energetic as they once were when they were younger!).

As our dogs get older, they slow down and don't burn off as many calories as they should, so we must keep an eye on their diet and be careful not to overfeed them.

If your dog is overweight, the chances are he's unhealthy!

Cocker Spaniel Weight And Sex

American and English Cocker Spaniel bitches are usually smaller than the male dogs; consequently, they also weigh less.

Cocker Spaniel Weight And Health

An illness may cause your dog to put on or to lose weight.

So if your dog loses (or gains) weight and there's no apparent reason for this loss or gain, I strongly recommend you take your pet to see his vet and play it safe!

Neutering your dog can also impact your Cocker Spaniel's weight because neutered pets no longer need as many calories.

If your dog is neutered, it's a good idea to reduce his food intake a little, or better still, change over to dog food for neutered pets which is specially formulated to provide fewer calories without compromising on nutrition.

Cocker Spaniel Weight: Summary

All dogs and puppies are different, and several other factors can affect your pet's weight. As we have seen, it's not always as simple as specifying a particular weight according to the dog's age.

It's also difficult to recommend a specific weight according to your pet's height alone because bitches are generally smaller than males, and it also depends upon the dog's frame.

Add the difference in sizes between the American and English Cocker Spaniel and the dog's lifestyle (how much exercise it gets), and you'd be forgiven for feeling confused!

It's best to feed your dog at regular mealtimes and avoid free-feeding your Cocker Spaniel because being the greedy little monsters they are, he just won't know when to stop!

I recommend you use some common sense when determining what's suitable for your dog.

For example, if he's a small dog, say 39 cm, ideally, you could expect him to weigh around 12 kg or just a little over or under that figure.

If the same dog weighed in at the top end of the scale, say 14.5 kg, he would be overweight.

Additionally, although two dogs may be the same height and weight, one may look overweight (or underweight), and the other dog may look just right - again, use your own judgement.

Don't get too hung up on exact weights, and please don't worry too much if your pet is a little over or under the weights shown on this page, especially if he's fit and healthy!

If you don't own a pair of scales, you could visit your vet and use theirs, or you can simply use your eyes and decide for yourself whether or not your dog is overweight - learn how here.

If you're really worried about your Cocker Spaniel's weight, I recommend having a quiet chat with your pet's vet. They will be able to give you all the reassurance you need.
