Cavalier King Charles Spaniel vs American Hairless Terrier - Breed Comparison

Derived from the Rat Terrier, the American Hairless Terrier was born in a litter of Rat Terriers in 1972.

The evolution of this breed is very different from other hairless breeds. The American Hairless Terrier was independently developed when a hairless pup was produced in a litter of normal Rat Terriers. The owners of this pup, Edwin and Willie Scott attempted to breed her to other Rat terriers but were not successful in having another hairless pup until years later. Then they had a litter with one male and one female hairless puppy.

From that point on they worked with a veterinarian and a geneticist to develop the breed until it was accepted as a separate breed from the Rat Terrier in 2004 and accepted into the AKC in 2016.

The breed is very rare and with hairless dogs breeding only produces about two thirds of the litter as hairless and one third as coated. If a hairless is bred to a coated terrier, the chances of getting hairless puppies are 50% hairless and 50% coated. It is very rare to get a hairless when breed two coated terriers. The difference between the American Hairless Terrier and other hairless breeds is that the hairless gene in most breed is a lethal dominant gene, but in the AHT it is a recessive gene.

The origin of the Cavalier King Charles Spaniel goes back many centuries. It was in 1928 that this spaniel breed was separated from the smaller King Charles and these were particularly popular with royalty in England.

In fact, Mary, Queen of Scots had one of these spaniels who accompanied her to her beheading. It was her grandsons who gave their name to the breed, and King Charles II, who reigned from 1660 to 1685 kept these dogs. After Charles II's death, the dog’s popularity waned somewhat. The dog was later bred with pugs giving them the familiar features they have today, such as the domed head and the shorter nose.

Interest in the breed revived, and a breed -club was established, drawing up a breed standard. Finally, in 1945, the Cavalier King Charles Spaniel was recognized as a separate breed.

There are not many health problems bothering this sturdy little dog.

The skin must be cleaned regularly often daily with soap and water. This is especially true if sunscreen is used as they are open to skin infections.

Hip dysplasia is also a common issue for this small breed.

Cavaliers are generally fairly healthy dogs but they are prone to mitral valve disease which can lead to heart failure. The heart as 4 chambers and each chamber has a one-way valve to keep blood from flowing backward. One of these is the mitral valve and it can leak over time resulting in a heart murmur. Dogs as young as 4 years of age can develop a murmur from a leaking mitral valve.

Congestive heart failure develops, your dog has a chronic cough and lacks stamina. A veterinary cardiologist may need to be called in to recommend some kind of medical intervention. The vet will evaluate your pet's condition and lifestyle before making a recommendation.

Other health problems which the Cavalier might have to contend with will be luxating patella as well as eye issues.

This condition affects toy breeds, occuring when the kneecaps slip out of place. It can be severe enough to cause lameness in the dogs leg, but fortunately it can be managed with an anti-inflammatory or even surgery.

They need to be fed at least 3-4 times a day in small amounts as puppies and twice a day as adult. Be sure to avoid overeating and obesity. Puppies need about 400 calories a day whether you feed four times or two times. The adult American Hairless Terrier needs about 500-600 calories per day. This might be half a cup to a cup per day.

Brushing:

The Cavalier Spaniel’s long silky coat will require brushing at least twice a week to remove loose hairs and to keep it healthy and shiny. This is one spaniel however, that won’t require trimming. However, because he loves to be playing outdoors, some owners do trim the dog’s feathers around the legs and paws.

Ear Checks:

As a dog with floppy ears, it will become essential to check his ears for wax build-up and moisture within the ears combined with dirt. This can lead to ear infections. Also the silky ears can be prone to matting. You can wash them gently with dog shampoo.

Dental Disease:

Smaller dogs like the Cavalier Spaniel are more likely to develop dental problems because of the structure of their skulls and jaws which are more compressed. Brush your dogs teeth 2 or 3 times a week with special canine tooth-paste and toothbrush.
