Hi, and sorry to respond so late. I am sorry your puppy is sick

My answer to you would be to seek good veterinary care. We are not veterinarians here and I would be afraid to give out any advice to anybody on how to treat sick dogs or cats because I am not qualified to treat sick animals. That is for a professional vet to decide. Besides, if you have any very sick animal, it's always best to take it to the vet. They're trained in treating sick animals, we're not.
I really wish I could somehow help you quickly, but you know I am not a vet! Sorry

I really do hope that your puppy gets better. Best of luck to you. Like I said: SEEK GOOD VETERINARY CARE as soon as possible.
