I am having a litter of puppies any day now. I already feed dog fod all natural large breed puppy food she has 24 hour access to it. She gets a vitamin daily and was at a healthy wieght before she was bred. She is just shy of 2 and is carrying her pups very well. This is her first litter but i have raised two other littlers from another female. I am looking for ways to help her maintain her weight after the pups are born. I have taken all the steps done lots of research and made sure both dogs were healthy pior to breeding. I am just looking for su ggestions to di.suss with my vet. Thank you for the help.
