Usually a dam doesn't gain much weight until 2-3 weeks before giving birth. We try to stay away from supplements, but tend to increase the amount of food per feeding for momma'.
Yes that is true. But I am still going to to everything in my power to help insure that she has healthy puppies.saddly with two non-health tested dogs there is a good chance the puppies will never be healthy no matter how well you care for the momma. They may suffer from some of the common chihuahua problems, like knee problems.
The vet says shes healthy, and she is up to date on all vaccinations and wormings. She also just had her teeth cleaned.If the momma dog is very underwieght she could be sick have you brought her in for a vet check?
