This would be due to a lack of pigmentation however, this trait is highly undesirable and, in fact, a disqualifying factor in the show ring.
all bulldogs have stubby short tails unless they are deformed...
Some English Bulldogs like to swim, but typically, Bulldogs can not swim. They are heavily built dogs who just can't keep themselves afloat. When they are near water, they need to wear life vests for their safety. Some English Bulldogs do like to swim, others do not, as with any breed of dog. Bulldogs have short muzzles and a dog life jacket is essential to keep the muzzle and head above water, for bouyancy protection and to stop the dog swallowing too much seawater.
Some dogs noses are pink or get pink especially the light haired breeds, like a white husky etc. It can also be pink from rubbing it on the floor, but you should see signs of a brush burn on his nose.
Some popular names for female English Bulldogs are Lulu, Roxi, Nana, and Lucy.
Your dog's growth similar to a mole pink in color on the top of his nose should be checked out. This could be cancer.
I have a English bulldog myself, and they have it because every dog needs a tail, that is just a part of the way they are. My dog does in fact have a curly tail, but when i see some other English bulldogs, sometimes they are not curly they are just stumps.
Because, my dear, cat noses are just like the rest of their body and have different colours. If the cat is black it will probably have a black nose, if its orange it will probably have a pink nose. It's like eye or hair color, not everyone is the same. :)
Usely the tail are dock some owners keep the tail and yes sometimes they do curl.
The American Bulldog is a bigger dog standing 20-28 inches at the shoulder (compaired to the Boxer breed's standard of just 21-25 inches at the shoulder) and weighing 60-120 lbs (avg. weight of boxer only 50-80 lbs).
All bulldogs are domestic breeds of dogs and thus there are no native wild bulldogs. However there may be some examples of pet bulldogs that have gone feral.
Some american bulldogs have webbed feet because it is an adaptation that only got to some parts of the breed.
gray horses have gray or black skin but may have some pink skin around their mouth and nose.
