there is only one pup left fat city, antg, the foster bitch is cleaning and toileting them, thanks lads for all your help. the sick bitch was taken to the vet a day or 2 after the pups were born, he thought her womb hadnt closed and had got infected, he checked incase a dead pup was stuck in her but there wasnt.he gave her an injection and a course of tablets. then at the weekend she was still bad so we took her to a different vet, he thinks it could be parvo, he said sometimes after a bitch has pups it can happen even tho she was vaccinated as a puppy.so he gave us stuff for her.
