My dog was sick, now won't eat or drink. Is it just the heat?

Pet's info: Dog | Pug | Male | unneutered | 1 year and 5 months old | 12 lbs

My dog had diarrhoea two days ago and was vomiting. He isn't being sick anymore or having diarrhoea but he isn't eating or drinking any water right now. It's very warm right now (22 degrees celsius) and I was wondering If it's just because of the heat or is there something wrong? (He's a pug by the way)

While extreme heat can cause heat stroke or heat exhaustion that could result in vomiting or diarrhea that doesn't sound like the case for Oskar. Heat stroke also causes weakness and difficulty breathing, and animals do not typically recover without intervention. Something else may have triggered the vomiting and diarrhea - it's possible that Oskar ate something he shouldn't, or that he has one of the other numerous diseases that can cause these signs. If he still is not eating or drinking I'd recommend seeing a veterinarian. Some of the tests they may recommend to determine what is causing Oskar's illness include blood work, abdominal x-rays or a fecal analysis. They might also recommend symptomatic treatment for his lack of appetite.
