If you're concerned that your Bulldog may be gaining too much weight, the best thing you can do for him is to consult a vet. Your vet may recommend changes to his diet and may suggest more exercise for your pet. Don't worry too much if you've been told to switch to weight-loss Bulldog food — there are many options available. You may also want to look at our dog food calculator to re-assess whether you might be overfeeding your puppy or dog.
