How Much Should a Cocker Spaniel Weigh?

When you think about the ideal weight of your cocker spaniel, don’t make the mistake of comparing it to other dogs. Each dog is unique and your dog’s ideal weight could be over or under another dog’s ideal weight. Consider the breed (American or English), size, age, sex, health status and lifestyle of your dog to calculate their ideal weight.

Do cocker spaniels change weight with age?

Due to their large appetites, cocker spaniels are prone to obesity as they grow older. You need to keep exercising your canine as much as possible as they age, even if their energy levels drop.

Observe their diet because they do not burn as many calories as they did when they were young, energetic pups. You might also get tempted to overfeed them because cocker spaniels are always hungry. Don’t. Instead, observe their meal times and serve them balanced meals in the right portions.

How Healthy Is Your Cocker Spaniel?

Your canine’s health has a direct impact on their weight. If your dog suddenly loses or adds weight, consult your veterinarian and get them checked. Most of the time, a spike in weight for your cocker spaniel indicates obesity or overfeeding, while a drop in the weight indicates that your cocker spaniel might have an underlying condition.
