OOHH poor thing all of my female dogs have severe phantom pregnancies, My oldest ibizan hound is having one right now, and they all produce milk OUr youngest basenji Lio kept on being in her phantom pregnancy and there was only one way out left…. last tuesday we got her spayed, it is better for her, that was my last breeding female , she only had one litter, but well health first !!! we love her to death anyway :)back to the topic: raspberry leafs??? that is only to make the pregnancy and delivery more easy for dogs, I have never heard of giving it in their seasons...... what is it supposed to do for a female in season?
anyway the vet here prescribes Lactafal or galastop to treat severe phantom pregnancies, and it works usually very well ( with the exception of Lio this time..... )
Maybe you can consider to spay her? as it is not healthy for females to get these phantom pregnancies all the time and I even heard that it might increase the chance of milkgladtumors..... anyway my oldest ibizan will be spayed for this reason soon too ( as soon as she gets out of this phantom pregnancy )
I dont think the females are very happy when having these severe false pregnancies, and the rest of my pack neither as she is not very nice to them in this period as well
