go to another veterinarian. if there aren't any specific tests to do, he/she can at least give some other type of medicine to help your poor puppy

Typically Antibiotics treat the symptoms, but may not address the core problems causing the symptoms. I would encourage you to look into researching Vaccines and the side effects they can have on many dogs. In addition...what sort of poisons may your dog be routinely exposed to? Are you using Frontline, Advantage, or other toxic flea and tick treatments? Does your dog receive a monthly heartworm medication. Heartworms ARE bad, they can kill, but the poison that many dogs ingest monthly to insure they do not get Heartworms is not all that great either! (It's a real, challenging situation...especially if you live in an area that commonly has problems with Heartworms!) There ARE alternative treatments for Fleas and Ticks that are NOT poison...such as Neems Oil. This you can find at Whole Foods...many other health food stores or on line by running a Google for it. It comes in oil form, which you can apply drops..once a week and rub in. Shampoo, and bar soap as well, plus you can make your own spray with about 8 drops added to water in a small hand spray bottle. Neems was approved by my neighbor's OBGYN while she was pregnant for keep the skitters off of her during summer. It can be used by humans, dogs, cats, horses or other live stock. It repels skitters, fleas, ticks and flies! IT IS NOT POISON and can be used on children and baby animals. Other toxins your dog may be exposed to include lawn and garden treatments, household cleaning supplies.... And the aforementioned Vaccines, which often cause skin, eye, stomach, ear and behavioral challenges. Just to cover your bases, I'd suggest you look for a Holistic Vet...and that this problem to them...they are often better at looking for obscure reasons over the "typical...run of the mill" possibilities...and so can help develop a cure, or figure out alternative ways to protect and treat our companion animals with fewer toxins. Best of luck to you and the pup, I hope a positive solution can be found soon!

Thanks.The vet gave him a shampoo and he's doing better.
