Genetics & Gender

Genetics and gender are two of the biggest factors that determine your Olde English Bulldogge’s size. They will be genetically more inclined to being larger or smaller, depending on the size of their parents.

Usually looking at the parents’ size will help give you a clue as to what you can really expect size-wise. Also, male Olde English Bulldogges are going to be generally larger in size than female Olde English Bulldogges are.


In general, nutrition is not likely to affect the growth of your Olde English Bulldogge as far as size goes. Even undernourished dogs will still maintain the height that they would have had.

The issue is that they might not be getting enough nutrients, which could make their bones weaker or could be the source of future health issues. It might not impact their size, but it will for sure impact their health.

Physical Activity & Health

Physical activity and overall health can also affect the dog’s growth, but it might not be the way that you expect. Good physical activity can help keep your dog the appropriate weight for his size, which can prevent future health issues.

Overweight dogs will still be the same height regardless, but they will not be as healthy or mobile.

If your dog already has health issues, it could cause stunted growth, but is more likely to just shorten the dog’s lifespan.

What If My Olde English Bulldogge Is Not The Right Weight 

If you are looking at the Olde English Bulldogge growth chart and thinking that your dog is not the right weight, there are a few considerations to think about.

The first, and most important, is where is your dog on his growth curve? The growth curve is the natural curve that dogs will gain weight using.

Every dog will have his own growth curve, so as long has he is gaining weight at the appropriate pace and has consistently done so, there is nothing to worry about.

If you are noticing that your dog is looking more overweight or you can see his ribs, then you might need to consider other options. For a dog that appears underweight, the first step is to increase his food slightly.

If his appetite is healthy, he should eat it. If your dog is overweight or is off his growth curve, it is best to confer with the vet to see what you should do.

What Is The Life Expectancy Of Olde English Bulldogges?

Dogs who are fed well, exercised well, and who are well-loved have a longer lifespan than dogs who are not well taken care of.

Their lives can also be cut short if they are not well watched and make mistakes that cause an early death.

Olde English Bulldogge Genetics And Common Health Problems 

While the Olde English Bulldogge is a classic breed that has been recreated, it is really a specific kind of mix of breeds that are working together to result in a set combination.

As a result, Olde English Bulldogges have fewer health issues that other purebred dogs do. This is a common situation with mixed breeds as well. Still, there are a few common health issues, including:

  • Hip dysplasia: This is a condition where the hip joints have not grown correctly, causing mobility issues as the dog ages.
  • Entropion: This is a common, but fixable, genetic condition where the dog has too much eyelid, so the eyelashes roll inward. This causes abrasions and pain, but it is correctable by surgery.
  • Bloat: This can be a fatal condition; it is where the dog’s stomach fills with food or gas and then twists, causing a major blockage. This progresses quickly and can be fatal.
  • Dermatitis: This just means a skin irritation and is controlled through diet most of the time.

Final Words 

While the Olde English Bulldogge breed was once considered extinct, the breed is back and makes for a charming pet.

Just remember that when you are looking at the dogs expected weight that you need to think about how quickly he is growing and whether he is staying on his own growth curve.

Feed your dog with good quality food at least twice a day and make sure that you can see the dog’s waist, but you should not be able to count his ribs with your eyes. If you do become concerned about your dog’s growth, always ask your vet for guidance.
