King Charles Spaniel vs Boston Terrier - Breed Comparison

Classified as a toy breed, the King Charles Spaniel is a small, pure breed dog that originated in the United Kingdom. The dog was named after King Charles II of Britain.

The dog actually has quite a long, illustrious history. People mistake them for the Cavalier King Charles Spaniel, but they are 2 different breeds, just sharing the same coat colors.The King Charles Spaniel was crossbred with the Pug early in the 19th century to shorten the length of the dog's nose.

With a face similar to that of the Pug, it is thought that these toy spaniels may have originated in the Far East.The earliest recorded pictures of toy spaniels in England were in paintings of Queen Mary 1 and King Philip.

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.

The King Charles Spaniel is a medium sized dog that stands at roughly 23 – 28cm and weighs anything from 3 to 8kg. He is smaller than the Cavalier King Charles.

He has a long coat which can be white, black and tan or a reddish-brown color. He has a domed head with a short, turned up nose and 'squashed' face similar to the pug. The eyes are large and dark and also protruding. The ears are set low and are long and floppy and the tail, once docked, is now left long and feathery.

Eye Problems:

The eye problems that you might need to know about with a King Charles Spaniel are entropian, cataracts and corneal dystrophy.

Heart Conditions:

Heart conditions could include mitral valve disease where the blood flows backwards through the chambers of the heart, leading to congestive heart failure.

Breathing Problems:

The King Charles Spaniel is a brachycephalic breed and these dogs can have upper airway problems. Breathing difficulties can also occur because of an abnormally small windpipe which is a characteristic common to brachycephalic breeds. You may notice rapid breathing with your dog , snoring, frequent panting, coughing and difficulty with swallowing.

Vet Checks:

As a dog owner, you have a responsibility to your pet. He will need to visit the veterinarian for all his puppy vaccinations as well as other vaccinations as an adult dog. He will also need to be de-wormed.

If you don’t want him or her becoming a parent, make sure your pet is neutered or spayed. If your pet is showing signs of an illness that he doesn’t get over quickly, get him immediately to the vet.

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.

Your King Charles Spaniel has a long, silky coat that will require brushing twice a week to control shedding and keep his coat free of matting.

His nails will also require regular trimming to ensure they don’t hook on anything. His long ears are also prone to ear infection, so be sure to check them inside and out for ticks and fleas and to also remove excess wax and dirt.

Teeth should also be regularly brushed with canine toothbrush and toothpaste.

Be sure to keep your King Charles Spaniel content and healthy by ensuring he goes on a long walk and that you play with him to build a strong bond between you and to ensure he doesn’t become bored.

Excellent, quality food is important for your spaniel. The best dog food manufacturers have age- and breed-specific formulas and there is the perfect one for your King Charles Spaniel. Homemade food is also excellent for this dog and you can add some cooked chicken, brown rice and vegetables into his kibble as a nutritious treat.

Make sure your spaniel has a warm, dry, peaceful place to sleep and wash the bedding regularly to keep him healthy and happy.

Ensure he always has a cool, fresh bowl of drinking water nearby.

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.
