Ever since Tuesday night, Sidney has been "off his feed". He's usually wanting to come after whatever we are eating and is eager for treats, but not lately. On Wednesday he was really lethargic and simply looked miserable. On Thursday his energy seemed a little better and we took a nice long walk. But he's still not interested in eating, even the sliced turkey we bought for training.
He's peeing normally. I've seen him poop once, it was just a little bit but it was not loose. No vomiting. He'll get up and bark if something alerts him.
I understand he might have eaten something that did not agree with him (maybe he visited the litter box...ewww), but how long can I expect this to last before I go from worried to REALLY worried? Is 5 days too long?
