Poor Gypsy. This could be due several things like a respiratory problem, eating something she shouldn't, all the hormones, a bacterial/viral infection, parasites and much more. Since she is pregnant, we have to be careful what medicines she gets put on. I would have your vet take a look at her to ensure all of the puppies are still okay. They will also be able to determine the problem and get her on the safest medications for her and the puppies. I hope this helps!

    Hello. This is not normal behavior for a late term pregnant dog. I am a bit concerned about the stuffed toy she is vomiting up. She may have eaten more than you realize, or she ate the toy because she is not feeling well. You do want to be careful with pregnancies so having Gracie evaluated by your veterinarian would be a very good idea. You do not want her to go too long as it is important that she not lose too much weight & condition during her pregnancy. I hope she is feeling better soon & thanks for using Petco Pet Education Center, formerly Petcoach.
