Matilida is a two year old female English Bulldog. She finished a heat less than two months ago, and seemed to be on an approximate 6 month cycle based on prior cycles. She is now acting very anxious, whiney, and exibits an odd behavior- standing high in her cage and "humping", something she's never done before. Could it be she's in heat again? We have two other dogs-both fixed, male and female Westies; the female fixed two weeks ago.

Usually Bulldogs come into heat every 6 months, just like most breeds do. The best heat to breed them is actually their 3rd heat or thereafter.

Ok, just as I thought. Now I have to figure out this strange behavior of hers.
