Tosa vs Greek Sheepdog - Breed Comparison | Petzlover

Known as the Olympus Dog or even simply as the Greek Shepherd, the Greek Sheepdog is a large to giant molosser dog from Greece. His purpose has always been to guard flocks and livestock from predators and he has been around for hundreds of years, looking much like the Great Pyrenees.

Some diseases to look out for include -

Dilated cardiomyopathy:

This is a disease of the heart muscle. The heart is enlarged and unable to have the right heart rhythm. The distended muscle isn't able to push the blood through the heart chambers to where it is needed. Cause for this dilated heart can be genetic, nutritional, infectious or metabolic.

Because taurine and carnitine are involved in good heart function, and low levels of these amino acids can cause symptoms of dilated cardiomyopathy, supplementation is useful, especially if you feel your dog isn't getting in the right kind of food.

Lyme Disease:

Borreliosis, a bacterial infection, causes Lyme disease, transmitted by the Ixodes tick. The tick bites the dog and the toxins gets into the dog's bloodstream, with the bacteria travelling to different parts of the body.

Typical symptoms in a dog includes loss of appetite, fever, no energy, swelling of joints and lameness, but symptoms can progress to kidney failure too or cardiac problems. Treatment will include antibiotics.

The Tosa is a formidable looking molossoid, but even so, this big, calm dog can succumb to illness. Some of these diseases you need to be looking out for include bloat,hip dyslasia and eye conditions.

Bloat for this dog can be life-threatening, and can often be because the dog is too hungry and he gobbles up his food quickly. Bloat is when gas can't escape, the stomach swells and twists – very dangerous. Rather give your dog two smaller meals – one in the morning and one in the evening, or even give several smaller portions throughout the day.

To help with eliminating health issues always choose a reputable Tosa breeder. You’re not likely to find one of these dogs in a dog shelter.

Grooming:

The coat of the Greek Shepherd is fairly long so it will need to be brushed at least twice a week to keep it free from matting and tangling. He is an average shedder and the brushing will remove all loose hairs, keeping the coat sleek and shiny.

Diet:

Feeding your Greek Sheepdog requires giving him top quality food as this will ensure he is healthy and can ward off common dog illnesses. If you're going to be feeding him kibble, make sure to go for the top quality brands, and as a treat for your pet you can add in some brown rice, pasta, brown bread, cooked chicken and vegetables.

Invest in the best quality ones that have nutritious minerals and vitamins. Try and give your dog some home-prepared food too – boiled chicken, brown rice or pasta, spinach, sweet-potatoes and carrots.

Never feed your dog things such as chocolates, peanuts, crisps, grapes, onion and food with spicy flavorings. This will just ensure digestive problems and having to get your dog to the vet.

Cool, fresh water should be available at all times.

The Tosa’s short coat isn’t going to require too much attention. A good brush twice a week will keep it free from loose hair and keep its shine and gleam. It’s why the dog is looked upon as being low maintenance.

Exercise:

These dogs are calm and fairly low-energy. Nonetheless, to maintain good health, he will need to be exercised. Ball games outside are always a good idea as well as nice long walks. Hikes into the countryside will be wonderful for this big dog.
