Is The American Bulldog A Healthy Dog Breed?
It seems unlikely that the robust American bulldog has any health problems when one looks at him. A dog may greatly benefit from a nutritious diet and enough activity to preserve his excellent health, and yet every dog, regardless of breed, has possible health hazards.
These problems for the American bulldog that may affect its growth involve hip dysplasia and thyroid problems.
The lifespan of the American Bulldog usually ranges from 10 to 15 years of age. That means, for a large dog breed, that they are a healthy one.
Hip dysplasia, being one of the most prevalent skeletal diseases in dogs, only affects a small percentage of large breed dogs, including the American bulldog. Your dog will have difficulty moving if the hip points in his hips didn’t grow regularly over time.
If the disease is hereditary, you’ll probably notice symptoms before the pup turns one. But what does hip dysplasia have to do with the growth of the American Bulldog?
Well, to cut it short: thanks to hip dysplasia being as it is, it can affect the dog’s growth. For instance, while having hip dysplasia, the pup can have slower growth, because of the painful hip joint which doesn’t let the pup move around, therefore preventing it from getting muscle mass and developing properly.
Reduced activity, particularly when it involves sprinting, leaping, or climbing stairs, a wobbling stride, soreness in the hip joints, decrease of thigh muscle mass, rear legs that are abnormally tight together, and strengthened shoulder muscles to assist support the dog’s burden, are also symptoms.
The diagnosis of hip dysplasia must be confirmed by radiographs, and the course of therapy will depend on the size, age, and severity of the disease in your dog. While some elderly dogs need joint replacements, young pups might benefit from hip rotation surgery.
Anti-inflammatory drugs and painkillers are helpful in treating the problem, and weight control is essential to lessen the strain on your pet’s hips.
The thyroid is an endocrine gland that dictates the functions of an organism. Many veterinarians say that the thyroid gland is the CEO of the whole organism, because it dictates the speed and the volume of the way things function in the body.
The genetic condition of hypothyroidism, which is caused by a deficit in the thyroid hormone, is common among medium and large breed dogs. His metabolism is slowed down because his thyroid gland isn’t producing sufficient amounts of the hormones triiodothyronine (T3) and thyroxine (T4).
Having hypothyroidism and generally a slower metabolism means that there is a possibility that the dog will grow shorter than it should.
The front of the chest and neck, sides of the body, sides of the thighs, and tail are among the areas that experience weight increase and hair loss as symptoms. Another symptom of hypothyroidism is a slower heartbeat, cold sensitivity, tiredness, and dry, thick, swollen skin.
Though the illness is irreversible, it can be managed with an artificial hormone treatment given twice daily. A blood test aids in diagnosis.
However, Fear Not, Because…
…The mere fact that a dog is susceptible to a condition does not guarantee that the dog will develop that health issue. Knowing everything your American bulldog could be susceptible to, can help you stay alert and keep an eye out for any symptoms of an illness he might be developing.
Additionally, if you’re looking for something like an American bulldog, choose a trustworthy breeder who is familiar with the history of his canines and can give you documentation of their genetic and medical histories. Dogs who have a record of hip dysplasia, for instance, won’t be bred by a responsible breeder.
Therefore, choosing a reputable breeder who takes great care of the litters as well of the parent dogs, will do the job.
Your American Bulldog size, and general well-being, both physical and emotional are determined by those initial two months that it spends with the breeder. Choose your breeder wisely!
Note that, when your female American Bulldog is in a heat cycle, it can be more sensitive, therefore more prone to catch a cold. Please take special care of her when in this phase.
The things that you can do are provide your dog with the best dog food and take very good care that the dog doesn’t go much over the average weight, in order to minimize any kinds of health illnesses that may go with obesity.
American Bulldogs take pleasure in using their many natural athletic talents, which include agility, weightlifting, hunting, and agricultural labor. Even if you don’t support hunting or live on a farm, taking lots of regular walks will still be effective.
Growing young, American Bulldogs may either be exceedingly amiable or distant and even hostile. How much socializing they receive as puppies greatly influences how amiable they are.
Unfortunately, bulldogs are sometimes grouped with the misunderstood Pitbull, giving this lovable and charming dog a terrible reputation for no good reason. Your dog may need extra attention and training to become a living illustration of how absurd these assumptions may be.
An American Bulldog growth chart is presented, in order for you to take a closer look while your pup is growing up. There are some differences between male dogs and female dogs, but that is almost obligatory between littermates.
