Hello, my dog has been on heat twice since we've got her a year ago. the first time she had a phantom. milk produced, swelling of stomach, tired all the time. this was in September.in December we got a puppy ( from another bitch), and this pup would try to suckle off her. now shes just had another heat and shes producing milk again. could this be because her body thinks that its her puppy? or is there another health problem i should be aware of? she couldn't possibly be pregnant either.
thanks in advance !
