Average weight for 5 month old cavalier king charles spaniel

The Association for Pet Obesity says that over half of the dogs in the United States are overweight. That number is the same in the United Kingdom, and it’s a growing problem in other parts of the world as well. This means that there is a good chance your Cavalier King Charles is overweight. There are many things that could be contributing to the extra weight gain, including health issues, lack of exercise, and/or too much food. First though, you need to determine if you think your Spaniel is overweight. If so, take her to the vet to have her checked for medical conditions and to decide on a diet and exercise plan to get her back to her svelte self. The following are three signs your King Charles Spaniel is overweight.

#1 – No Definition

Cavalier King Charles Spaniels should have a chest and rib cage that tucks up to a smaller “waist” at their hip bones. If you can’t feel those ribs or tell where his rib cage ends and his hips begin, it’s probably time to diet. Dr. Sophia Yin’s website has a great, easy to follow guide for checking this.

#2 – Unable To Reach That Itch

Does your Cavalier try to scratch her ear and just can’t reach? Or maybe it’s impossible for her to bite herself. She should be able to groom herself without a struggle. If they are overly round, grooming becomes impossible. If that’s the case with your King Charles, it’s time to diet.

#3 – Easily Overexerted

Do you walk a few steps and your Cavalier is already panting and wanting to stop? Barring hot weather, this is a sign that he is out of shape and probably overweight. It’s time to talk to the vet about a diet and exercise regimen that will slowly get him back on track. Be careful about pushing your King Charles Spaniel to exercise more than their body can handle – that can cause other issues.

History of Cavalier King Charles Spaniels

The history of the cavalier King Charles spaniel dates back to Renaissance times when toy spaniels were kept by European nobility. King Charles I and Charles II had toy spaniels in the 17th century in Britain, and these dogs were prized by the monarchs. The toy spaniels were bred with Asian toy dogs, such as pugs and Japanese chin. This created what was known as the English toy spaniel, which had a flatter face and domed skull than the modern cavalier King Charles spaniel.

However, in the 1920s, there was some interest in reviving the old-world-style of toy spaniels, and a wealthy American named Roswell Eldridge offered money to British breeders to recreate this type of dog. The result of this breeding was today’s cavalier King Charles spaniel. There are four color patterns of these dogs that make them distinctive: rich red, black with tan markings, black markings on white, and chestnut markings on white.

The American Kennel Club started officially recognizing this breed in 1995. But the dogs made their appearance in America starting in the 1940s and 1950s.
