hi all just a quick question,
my girl had her last season in february but yesterday started to bleed again, have had her the vets and he says she has no infection she is 100 % healthy etc just looks like she come back into season early

She has always had a 6 month cycle until now, Is it possible for a bitch to go from a regular 6 month cycle to 4 months ? My girl is 4 n 1/2 and had a litter of healthy pups 8 months ago. im just really confused by this so any advice much appreciated, i have seperated her from my male anyway just as a precaution as we not ready for any more puppies just yet
thankyou KwackerZ9
