He gathered the best dogs he could find throughout the rural South and bred them back into popularity among his family and other rural families. His father bred the American Bulldog before John did and they have bred them longer than any other in any part of the world.

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 Collie is a healthy dog breed generally, but just like with all other dogs, they are also prone to certain health conditions. It’s not to say that your Collie will get these diseases, but it can be beneficial to you and your pet’s health to be aware of them if you’re looking at the Collie as a pet.
This is a condition where the skin of the nose peels and oozes and left untreated, it can be painful for your pet and could even lead to cancer.
This is an inherited eye disease that can actually lead to blindness. When certain parts of the eye don't develop properly it can lead to CEA - a genetic disease found in Collies as well as other dog breeds. The disease is also known as Choroidal Hypoplasia and brings about changes and abnormalities in the eye.
This is an abnormal formation of the hip socket and certainly dogs with hip dysplasia should never be bred as it can lead to pain and lameness.
The Collie will need grooming because of his long hair, and you will need to brush it at least twice a week to rid it of loose hairs and to keep it free from tangles. This is especially important if you live in the country and he leads an active lifestyle running through fields.
Keep a constant check on your Collie’s ears because dirt build-up can lead to an ear infection. Your vet can advise you on how to clean your dog’s ears. Make sure you have your Collie’s nails trimmed.
To cater for your Collie’s size and activity levels, make sure to feed him good food that meets his nutritional needs. Protein is the most important nutritional need for dogs, and apart from feeding your dog quality kibble, protein should also come from raw, animal-based sources such as meat, fish and poultry.
