Kai Ken vs Estrela Mountain Dog - 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 Kai Ken dog hails from Japan and is both an ancient and rare dog. In fact the dog was discovered in 1929 in the Kai province near Mount Fuji. The dog has the nickname Tora Inu in Japan which means 'Tiger Dog'. Maybe its got to do with the brindle striped coat or his bravery.

He falls into the working class category. In 1931, the Kai Ken Aigokai registry was formed to preserve the dog. In fact in this year Dasuke Adachi discovered these dogs and in 1934 was actually designated a Natural Monument in Japan and also protected by law.

The Estrela Mountain Dog can live to be between 10 and 14 years of age, but as with any large dog, he will have a tendency to suffer from hip- and elbow dysplasia.

Dilated cardiomyopathy is another common heart failure disease found particularly in large-breed dogs. The Estrela is prone to this disease and you’ll notice he has shortness of breath, abdominal swelling and coughing. The disease may not be curable, but there are certainly treatments for it.

With a lifespan of 14 to 16 years, and given the genetic purity of the Kai Ken, you aren't likely to battle with congenital health problems with your dog, but it is always good to be aware of certain minor health issues that he could succumb to.

He can suffer from a few common dog diseases such as progressive retinal atrophy or hip dysplasia.

Progressive Retinal Atrophy:

This is a disease of the eye where there is wasting of certain parts, and in this case the cells of the retina develop abnormally. This can eventually lead to blindness. It’s an inherited disease that can occur in pure- and mixed breeds, and dogs with PRA shouldn’t be used for breeding.

It isn’t a painful condition, and the first symptom usually noticed in a dog is night blindness where you may notice him bumping into things at night and being reluctant to walk around in the dark.

Diet:

The Estrela Mountain Dog is a large dog and thankfully, when it comes to feeding him, experts in dog feeding have come up with commercially manufactured dog feeds that particularly cater for a dog’s age, his size and any illnesses he may have.

As a large dog, your Estrela Mountain Dog can suffer with joint problems such as hip dysplasia. For hip dysplasia you want to be looking at a dog food for large dogs which contains joint-health ingredients. An ingredient in the dog food such as glucosamine can work to reduce the damage brought about by hip dysplasia.

Mix in some cooked brown rice, vegetables and chicken into his kibble from time to time. You want your pet to live a long, healthy life and raw meat added in occasionally can increase your pets energy levels, reduce the risk of joint disease and ensure a shiny, soft coat. Raw meat can provide iron, zinc, vitamins, minerals and potassium.

Grooming:

The Estrela isn’t a huge shedder, but his beautiful, thick coat will require brushing twice a week. 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.

Even though the coat is thick, the Kai Ken will require basic canine care, so a brush twice a week will be enough to keep the coat free of loose hair. He sheds more heavily a couple of times a year and then he will require more brushing.

He has always been used to hunt so he is a dog that will require regular exercise such as walks, hikes, swimming and ball games.

The nails of the dog should be trimmed regularly once they become long as long nails can be hazardous and can hook onto things, causing injury to the nail area.

The ears of the dog should be checked regularly for fleas and ticks, and teeth should also be brushed with canine toothbrush and toothpaste.
