Amoxicillin causing excessive thirst in dogs?

Anon_168982 posted:
My neutered Aussie/Chow mix is 9 years old; he recently developed a UTI, and is on 500mg Amoxicillin capsules. Before he was on the antibiotic, he did not drink excessively, nor did he really have a decrease or increase in urine production. The reason we discovered he had a UTI is because he had blood in his urine. Took him to the vet, and all of his vitals were perfect, and so he's just got a bit of a UTI. Ever since starting the Amoxicillin he's been drinking a lot more water (even with the additional water I've been adding to his food just to keep him hydrated). Nothing else is unusual about his behavior, in fact he seems to be getting over the UTI. I've looked online and seen that others have had the same experience with their dog being on Amoxicillin, but not really from a trustworthy source. I've called the vet, and they say that it's unlikely that the antibiotic would cause that. I'm not overly concerned because he seems to be improving, and he's going back to the vet in a week for a check up anyway; but I was just curious if anyone on here has experienced this side-effect with their dogs after taking Amoxicillin?

There may be a medical reason for this, but I wonder if it is because of a bad taste in his mouth? I ask because when I take antibiotics I get a terrible taste in my mouth and consequently drink a lot of water. It's hard to ask a dog, I know, but I wonder if that might be the cause.
