Hi, a 1 & 1/2 yr old dog to be quiet something is WRONG, is your vet a really good vet?? sometimes there’s better vets then others, like human Dr’s sometimes there’s just better Dr’s, ask vet or new vet to test for “SLE Lupus” or ask vet could it be Canine Lupus & see what the vet says? I know Lupus is hard to detect, first signs are white blood cells are elevated…
also have you joined any GSH groups?? sometimes you’ll get more answers from other GSH owners as they have the same breed also was he brought from a breeder? if yes contact the breeder & ask if his parents or grandparent have any illnesses??….
It’s sad when they are un well & they can’t speak either..
With his food what was he eating when he became ill???
We have had 2 Australian foods in Australia that have caused bad health problems in cats & dogs…..I don’t think it’s the waterchestnut… with the blood test did they test for Pancreatis??
