Sealyham Terrier vs Estrela Mountain Dog - Breed Comparison

The Sealyham Terrier is a rare dog breed originating in Wales. The dog was developed in the 19th century by Captain John Edwardes at Sealyham House. The Sealy has been associated with members of the British Royal Family, but its numbers declined to such an extent that it was listed as a vulnerable native breed by the Kennel Club.

The Sealyham Terrier club was created in 1908 and the dog breed was officially recognised by the Kennel Club in 1911. This dog is now recognized by all the major kennel clubs. The American Sealyham Terrier Club was founded in 1913.

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.

This is a hardy dog breed and you don’t hear of many health problems associated with him. It seems as though you might have to watch out for an eye condition known as lens luxation. It's an eye condition with dogs where the lens slips out of position because of weakening of the fibers that hold it in place.

There is a lack of fluid in the eye causing optic nerve damage and this can lead to blindness.

Retinal Dysplasia is another eye problem . This is a developmental malformation of the retina that the dog is born with. Symptoms in dogs are a reluctance to jump off things such as the bed or he may even bump into things.

Atopic Dermatitis is something the Sealyham is more prone to. Its an allergic skin disease which drives a dog mad with its itchiness. Your pet will certainly need treatment from the vet to relieve it.

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.

Provide your Sealy with his own warm, dry bed.

Brush the long, weather-resistant coat at least twice a week. Hand-stripping of the coat will maintain the wiry, hard texture, but because this method can be quite a laborious process, many Sealy owners rather have their dog professionally clipped.

Check inside his mouth for bad teeth as well as inside the ears for signs of infection. His eyes should also be clear and free of discharge.

His nails will also need to be trimmed.

The Sealyham doesn’t require a lot of exercise but he must at least be given a walk every day.

Ensure the vaccines are up to date. They start when your pet is just a puppy. Remember to get your dog to the vet when you suspect that he is ill.

Feed your Sealyham with good food. Make sure you’re feeding your pet a high quality food as this promotes health and longevity. Provide your Santal Hound with top quality food to ensure his health.

Always choose the quality commercially manufactured foods on the market – those that have natural, good ingredients in them. Try to include some home-made food for him which can be simply mixed into the dry kibble twice a week.

There is no need to offer your dog a host of different foods. Dogs want simplicity and consistency. Boiled chicken, brown rice or pasta and spinach, sweet potatoes and carrots is super tasty and nutritious. If you can, also try and include a little bit of raw meat to his diet occasionally as this can go towards ensuring he doesn’t get skin diseases.

Make sure that a constant supply of fresh, cool water is available to your dog.

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.
