we just found a basset hound out side are house who allmost got ran over. we went a head and took her in...im not sure how old she is or who her owners are. she was really underfeed, you could see her bones, hip bones too. but her belly is quit big.. now we are worry she is preggo.. we dont want to take her to the vet and spend money to find out becuase we may not have her that long since we are looking for her owner. but since we may have her a few days we dont want to wake up to find puppys lol. so how can i tell if she is preggo. and if she is what do we do?? and if shes not preggo is it ok that her belly is so big and kinda hard?
