Estrela Mountain Dog vs Cavalier King Charles Spaniel - Breed Comparison

Also known as the Cao da Serra de Estrela, the large Estrela Mountain Dog from Portugal is an ancient breed, having been used for centuries to guard homesteads and livestock.

The Estrela, as a herding dog, has been developed over a long period of time because shepherds particularly wanted a dog that could survive in the mountains and be strong enough to guard livestock from predators.

The first official recorded breed standard was published in 1933, with an attempt to make the Estrela a distinct breed with a hooked tail and double dew claws.

Today the Estrela is a dog which can be found in other countries beyond Portugal, and in fact in 1973 pairs of the dogs were imported to the United States.

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.

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:

It’s your chance to check him over for fleas and ticks as well, and the entire grooming process – checking his ears, nails and teeth – is an excellent bonding experience for you and your canine friend.

Exercise:

The Estrela may be large, but he is fairly calm. He’ll love to join you on your daily walks or for a ball game in the garden. He can adapt to life in the city or the country, but his big size will mean he isn’t suited to a tiny property.

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.
