How much bigger will my French Bulldog get?

French Bulldogs usually reach their full height when they are between nine and twelve months old. As short dogs, French Bulldogs barely double in height from three months of age to 1 year old.

You can also reach out to your French Bulldog’s breeder for a precise estimate of your pup’s full size or take a look at your dog’s paws. If their paws look oversized next to their legs and body, this is a telltale sign that they are still growing!

How do I make sure my French Bulldog is healthy?

As a purebred dog breed, French Bulldogs are more prone to genetic health problems. In particular, French Bulldogs are predisposed to skin problems, ear infections, diarrhea, eye problems, spinal injury and respiratory distress caused by their brachycephalic syndrome. Brachycephalic syndrome causes them to have a flat nose and shorter esophagus, creating a heightened risk of breathing problems.

The Journal of Veterinary Internal Medicine found that about half of French Bulldogs have significant breathing problems and 66.7% have stenotic nares, which are overly tight nostrils that restrict their breathing. In addition to this, French Bulldogs are prone to obesity, which can lead to type 2 diabetes, osteoarthritis, disc disease, high blood pressure, heart disease, and further respiratory issues.

Keeping your French Bulldog at a healthy weight is one of the best things that you can do for them.

According to the Veterinary Centers of America, French Bulldogs require minimal, but daily exercise. Most French Bulldogs do well with a leisurely walk or active playtime. Be careful with taking your French Bulldog out in hot weather though as their brachycephalic syndrome makes them prone to overheating and heat stroke. As a general rule temperatures over 80 degrees should be avoided for French Bulldogs.

In addition to a healthy diet and daily exercise, regular veterinarian appointments are critical to your French Bulldog’s long-term wellbeing. A veterinary professional can run regular tests to assess your French Bulldog for health problems, treat your French Bulldog, and give you personalized recommendations for your pup’s health.

As loving pet parents, we never want to think the worst could happen to our furbaby. However, we must prepare for both everyday costs, like vaccinations and veterinarian appointments, and emergencies. Dog Insurance is here to help you with emergency costs, as well as expected costs like veterinarian care (see the wellness options many pet insurance plans offer).

Only 19.44% of pet owners say they’d be able to cover a $5,000 expense out of pocket, which leaves many pet parents in a pinch should their French Bulldog need emergency care. Pet insurance can help you provide your pup with quality routine and emergency care. Dog insurance gives you peace of mind knowing that when the worst happens, all of your decisions will be based on your pup’s needs instead of financial restrictions.


Key Takeaways

  • On average, French Bulldogs weigh between 17-28 pounds at age one, with 11-13 inches in height.
