I rescued a 4 month old puppy from a street person - looked very sick. Vet tested for distemper. Results were negative. 3 days after negative results, puppy started having tremors - not able to stand w/out bobbing, head bobbing, still with gooey eyes, nose. Back to vet - he's pretty sure it's distemper (negative results in late stages are common). New antibiotics, valium. I give lactated ringers sub-Q. ANY HOPE?
