Cavalier King Charles Spaniel vs Boston Terrier - Breed Comparison

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.

Nicknamed the American Gentleman, the Boston Terrier is the result of crossing the British Bulldog with the white English Terrier. At first the Boston Terrier was bred to be a fighting dog, but since then, undesirable characteristics have been bred out and today the Boston Terrier is regarded as an indoor dog that doesn’t tolerate extreme weather conditions.

The breed emerged in the 1870s when Robert Hooper from Boston bought a dog thought to be a mix of a Terrier and Bull type lineage. A specialist breed club was formed in 1891 and in 1979 the commonwealth of Massachusetts named the Boston Terrier the Official State Dog. By the 20th century, the breed’s color and patterns were standard and an essential feature.

Your Boston can be your Best Friend

Your Boston is a Terrier and that means he is full of life and will require being exercised by you. He can’t just be left outdoors day after day because this is one particular breed that can’t adapt to changing weather conditions. He likes being inside where the temperature is more even. Look after your Boston, because if you do, you’ll be rewarded by having one of the best friends you’ve ever had.

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.

Patellar Luxation:

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.

Boston Terriers are generally healthy, feisty little dogs but it is always wise to know that you may well come across some health conditions that can affect your pet.

Eye Problems

Your Boston may well have to contend with cataracts, and in the dog world, this isn’t only an ailment for old dogs. Juvenile cataracts can develop in young puppies already. Cherry Eye is another eye problem with a prolapse of the gland of the third eyelid. It is also an eye disease than can be found in young dog of less than a year old.

Deafness

Boston Terriers actually have a fairly high incidence of deafness in one or both ears. White Bostons tend to produce more puppies with deafness.

Brachycephalic Syndrome

The Boston Terrier is a brachycephalic dog and therefore more predisposed to Brachyphalic Syndrome where the dog battles to breathe because of too much soft tissue which forms in the airways.

To avoid many dog diseases with your Boston, buy your puppy from a reputable dog breeder who screens dogs used in a breeding program as this prevents puppies inheriting genetic disorders.

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.

Exercise

The Boston Terrier is a lively dog, and even though he doesn't have any extreme exercise requirements, he will still require you exercising him by taking him on walks, or having ball games with him. As an essentially indoor dog, he can even enjoy some quieter indoor games.

Feeding

You’ll be able to gauge how much your pet requires in terms of high quality food, but by the time he is an adult, he usually has one or two bowls of food a day. Size and age play an important role in determining his eating habits. Home made foods made up of rice, meat and vegetables are always welcome for your pet and these can be added into his top quality commercially produced dog food. For a healthy dog who is free of skin problems include some raw meat in the diet from time to time. Always make sure that there is a bowl of fresh, cool water which is available 24/7.

Grooming

With his short coat, the Boston Terrier isn’t a heavy shedder and is low maintenance in terms of keeping his coat groomed. Brush him at least twice a week to remove loose hairs and to also prevent flea and tick infestations. Brush his teeth 2 or 3 times a week to ensure no plaque build-up which can damage the teeth. Never use human toothpaste, but invest in special toothpaste and -brush for dogs. If he is essentially an indoor dog, you may have to get the vet to trim his nails too.
