Ckeuhl -- we always have a lot of people here with heartfelt advise who share their different experiences, etc. But, your little guy is seriously ill, and I'm glad you are getting professional care for him.

With my experience in medicine, I certainly also suspect that only fluid retention could cause that much weight gain in such a short period of time.

And - there are so many different conditions that can cause this.

Please keep going to your vet, take his advise, and follow his treatment plan religiously. Getting more than one opinion is certainly worth doing when you are dealing with a seriously ill little pet.

I hope your puppy has something that can be treated - and does get better.

I wish you the best of luck. Please keep us informed about what you learn.
