Purchasing an English Bulldog can be a stressful process, due to their health problems there is a lot of research that you need to do into your potential puppy to ensure it is going to live a happy and healthy life.

When researching potential problems that an English Bulldog might have, you may think, why do English Bulldogs have an underbite?

An English Bulldog may have an underbite due to their short, squashed faces caused by being a brachycephalic dog breed. Their squashed face will often result in their lower jaw being longer than their top jaw, which causes an underbite.

Not all English Bulldogs will suffer from an underbite, but the majority do, however some cases are very mild and others are more severe.

English Bulldog underbite problems

There are several problems that your English Bulldog may suffer from if they have an underbite, and these range depending on the severity of your dogs underbite.

If your English Bulldog has a very mild underbite which is barely noticeable, then it is likely that they won't suffer from any issues at all, and they will live their life unhindered by their underbite.

If your English Bulldog has a severe underbite, then the biggest problem that they will have is an inability to eat/chew food properly, which can make eating extremely uncomfortable for your bulldog and leaving to it potentially chocking on food it has been unable to chew.

Can you fix an English Bulldogs underbite?

Unless your English Bulldogs underbite is causing it problems, such as an inability to chew, there there is no need to consider fixing its underbite.

If the underbite is severe and is causing your English Bulldog problems, then the first thing you should do is seek professional advice from your vet to see if they believe that an underbite correction is required.
