Gran Mastin de Borinquen vs Estrela Mountain Dog - Breed Comparison

The Gran Mastín de Borinquen is also referred to as the Puerto Rican Mastiff or the Mastín Borincano and is actually native to Puerto Rico.

The dog seems to have originated long ago already during the 16th century. Its a dog that descends from a number of dogs, and the dog from these crosses became a huge, ferocious dog.

For centuries the Gran Mastin de Borinquen was used to protect the estates of the Spanish nobility. Today the breed is considered rare and it isn't recognized by any major kennel club as a standardized breed.

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 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.

Exercise:

Dogs that have been spayed or neutered as well as senior dogs will require less calories. If you buy commercially manufactured food, check the labels carefully and buy high quality food for a large breed.

Don't just feed your Gran Mastin kibble everyday but alternate it sometimes, mixing in some raw meat into his kibble or mixing in some cooked chicken, rice and vegetables.

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.
