We purchased a 'mini' bulldog last year and we too thought that he would end up being much smaller. He is a little over a year old and is 59 lbs. Although he doesn't have the typical normal size English Bulldog stature, he isn't a miniature by far. I have also stopped referring to him as a 'mini' because people just look at me like 'there is nothing mini about that dog'.
On the other hand when we received him we took him to the vet the very next day and they said he was very healthy and we haven't had any health issues with him. Elena was very nice when we wanted information and even provided us baby pictures and pictures of the mother. However, when I emailed her a couple of times after we received the puppy about a couple things-no response.
We did our homework before we dropped $2, 500 online so we were aware that Elena was in Florida and that the puppy wasn't. I did ask if we could visit the puppy before we purchased it and she said that that wouldn't be a problem and provided me a phone number of where the puppy was (even though we never did). I think she said that her sister was taking care of the puppies for her and she was in charge of all the paperwork/money stuff in Florida. When I met the puppy deliverer (he was delivered by van) they had numerous different types of puppies with them that they were delivering all over the states. The driver was really nice and when I asked why she was delivering different types of dogs instead of just 'minis' she said that she delivers for many different breeders. I don't really know what really was going on, but that was the story that I got.
Of course I love our dog, but he is definitely not a small dog. The vet says he is healthy and isn't overweight. He gets fed exactly what the vet recommends and runs around plenty in our fenced backyard when the weather is nice.
