I know you said you answered this question, but I have looked on the general site and the dog site and cannot find the answer.
My bulldog had pups in January and was due to go in heat in June. She has yet to come into
Sorry about any confussion and I will look into the problem. Anyhow, I would not be terribly concerned if your pet did not go into heat when scheduled. Some dogs go into heat 1-2 x yearly. I would have your vet look at her to be on the sfe side but I am willing to bet that she is healthy. Good luck, vetcare
