I just got a 1 yr old English Bulldog last Tuesday and took her to the vet over the weekend for a checkup. Her previous owners assured me she was healthy, but after a $250 vet bill due to a yeast infection in both ears and a bladder infection, I was quite upset. What on earth causes these types of infections? I don't want this poor little girl to have to go through anything like that again. She is on 3 types of meds and a special food for her her bladder.
