Though generally healthy, the American Bulldog is prone to a few problems.
This is a serious issue in many breeds of dogs and is especially prevalent with the American Bull Dog. This may seem ironic in such a short legged dog but it is unfortunately very common. It is a genetic disorder that causes the bones in the joint to separate and causes the dog much pain and lameness.
Due to skin folds you need to be care and watch for irritation and infection in the folds. They are also prone to ear infections.
The American Bulldog is prone to overeating and all the health issues that presents. With short legs and a genetic predisposition to arthritis and hip dysplasia, obesity is a real health risk for your bulldog.
The Korean Jindo dog is looked upon as a generally healthy dog breed with no serious genetic problems to talk about. Look out for eye diseases and dental decay as well as hypothyroidism, a common disease in dogs where you notice deterioration with the coat – thinning, dry and dull.
The dog’s skin also becomes flaky and you’ll notice that your once energetic pet is now gaining weight and is lethargic. Get him to the vet. Hypothyroidism can be treated simply by your vet to get your pet healthy once again.
The Jindo has a double coat and this sheds heavily about twice a year, so certainly during these shedding periods you will need to brush his coat twice a week to keep it free from loose hair.
Never just assume that your dog is healthy and happy. When you brush him, check him over for ticks and fleas, check him for any unusual lumps, make sure his nose is wet and that his eyes are bright. Look at the condition of his fur, check his teeth and inside his ears – there are lots of tell-tale signs that can indicate that all is not well with your pet and then you need to get him to the vet.
As a medium-sized breed, if you feed your dog commercially manufactured food, he will require a high quality food that has been formulated for a dog of his size and his activity levels. Mix some home-made cooked chicken, brown rice or pasta as well as vegetables into his kibble and try to include some raw meat in occasionally too. He needs to always have access to fresh, clean water.
The Jindo is a high energy dog, and with his bright face you can tell that he is always ready for action. Long ago he was bred to perform hunting and retrieving type jobs, and with their stamina, they require having a busy day.
They certainly require a significant amount of exercise and mental stimulation, so you will need to include him in your daily walks and give him exciting ball games.
