Please do not feed yougurt or milk to your puppy. Even post recovery, pups remain nauseous due to the strong medications that were given to them. You can start by given them fluids through droppers or syringes (http://www.dogspot.in/heres-h
ow-you-can-administer-medicine s-to-your-dog/). Your vet will be in a better position to help you with the schedule of feeding liquids. Gradually you can proceed to boiled liquid food.
Do connect with your vet for a complete understanding of what fluids can be given to your pup. If your pup has developed signs of pnuemonia, we would suggest complete medical care for your pooch. Please do not administer food or medicine without consulting a veterinarian.
We wish your pup a speedy recovery!
