Leonberger vs Cavalier King Charles Spaniel - 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.

Hailing from Germany, and more specifically the city of Leonberg, the Leonberger is a giant dog breed.

A resident of Leonberg, Germany, was looking to develop a dog that resembled a lion and in 1846 it was announced that such a dog had been developed by crossing a Newfoundland, Saint Bernard and Pyrenean Mountain dog.

It was after 2010, when the Leonberger Club of America joined the American Kennel Club, that the strict breeding rules were no longer mandatory for all Leonbergers.

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.

Leonbergers are strong, generally healthy dogs. It is said that very large dogs like this don’t live as long as smaller dogs and they also face more health issues. Orthopedic issues such as hip dysplasia are more common with large breeds.

Hip Dysplasia:

An orthopedic problem like this is a misalignment of a joint. This large dog also tends to develop elbow dysplasia too. Fortunately today, hip- and elbow dysplasia is controlled because of efforts of breeders to have their Leonbergers screened.

Nonetheless it is important to know about this ailment. The word ‘Dysplasia’ is referring to an abnormality of development. With both hip- and elbow dysplasia, there is abnormal development of the joints, and osteoarthritis can build up, causing lameness for your giant canine.

Cancer:

Cancer is sadly a leading cause of death in dogs over the age of 10 years. Lymphoma is a blood-related cancer – a tumor of the lymph nodes. Dogs can develop different forms of lymphoma. The warning signs are a lump or a wound that won’t heal, swelling in the bone and abnormal bleeding.

Luckily cancer is very treatable in dogs, but you need to get your dog to the vet as soon as possible.

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.

That long coat of the Leonberger is going to require some brushing at least twice a week. He is also a moderate shedder and you want to get rid of all that loose hair and to keep him looking well groomed.

Diet:

A proper, nutritious diet is an essential part of having healthy, happy dogs and if you’re unsure about how to feed your giant pet, speak to your veterinarian.

The best diet for dogs is always very debatable, but essentially it needs to be kept simple. Try and invest in the very best commercially manufactured dog food for large breeds. Every dog wants a tasty home-made morsel from time to time. Add in cooked chicken, brown rice as well as cooked or raw vegetables. Raw meat can also be added in from time to time.

You want to avoid feeding the Leonberger puppy a high protein diet as this encourages rapid growth and you want to avoid that.
