Good With Dogs:⬛⬛⬛⬛⬛⬛⬜
Every dog, just like every human is different. Some can easily digest a high-protein food while for others it is too rich for them. The best thing to do is to put your puppy on a Large Breed Puppy dog food, it is specially formulated for your puppy to help slow his/her growing so that they have the most amount of time for their bones to grow adequately for their body mass. Then putting your dog on a large breed adult formula once they are a year old for at least another year is perfect. Afterwards you can put your dog on a regular adult formula and there shouldn't be any problem. Please note that your dog will do much better on a grain-free dog food than one that has grains and corn. Dogs were designed by nature and humans to be carnivores first. Corn is very high in vegetable protein, and so it is put into the mix in cheaper dog foods since there is no sub category for vegetable protein and animal protein.
The Olde English Bulldogge was not meant to be a "dog park" dog. They are prone to dog on dog aggression and unless well socialized can end up with behavioral problems such as the one your dog already displays. If she does not do well with other adult dogs, it would be hard to say if she would like a nippy, jumpy, pushy puppy around. Especially on her territory, since she was there first. Talk to your breeder, where you got her and if at all possible, ask a friend or family member that has a puppy to bring their pup over. If you got another OEB, remember that they are going to both be showing the same behavioral traits.

Welcome to having a Bulldogge. They are known for their gas, haha. But there are things you can do to help minimize the gas. Putting your dog on a high quality, grain-free dog food will give your dog the best nutrition as well as help with the gas. I would also suggest a 'ball bowl' or another type of bowl that makes a dog slow down to eat. Dogs that eat quickly take in too much air, that causes them to have more gas in the first place.
Olde English Bulldogges are not known for their swimming capabilities or actually wanting to swim. If you want to show your dog that she does not have to be afraid of the water, get a small kiddy-pool and fill it with clean, cool water about 2 inches in depth. Then take some hot dogs, cut them into smaller pieces and put them in the pool. Your dog will realize that water is fun because there is food in there! As she becomes more comfortable with the water, make the depth of the kiddy-pool more so she has to put more and more of her face under water to get the hot dogs.
