I have a chihuahua mix rescue, I am not sure of her age but she seems to be young about 2-3 years old, seems to have come from a home as she was spoiled but dirty. She is pregnant, I am not sure how far along but my vet estimated 4 weeks, nipples are long and her stomach is large and hard. She acts very oddly as she does not finish her meals, shes very clingy. I have never taken care of a pregnant dog so I am not sure if this is normal. My only question is does the fact that she was a stray for the first month of her pregnancy have a neg. affect on the puppies health? I know there isn't a yes or no answer but is there any hope of the puppies being okay even if her nutrition wasn't great or maybe even there? She does not finish her meals, shes pretty picky and although her stomach is large I feel her spine from touching her back and I see her hip bones but the belly seems to keep growing. My vet gave me liquid vitamins and told me to feed her boiled chicken and rice, no raw. I have but she eats only 1/2 of what I serve her all the other dogs try to munch down the plate. I also leave her kibble and she eats one kibble at a time, I want to feed her more but I cannot force her.
