Dog panting, vomiting, sad after AC broke. Is it heat stroke?

Updated On September 23rd, 2025

Pet's info: Dog | Miniature Schnauzer | Male | neutered | 8 years and 2 months old | 24 lbs

Our a/c has been broken, and my 8 year old mini schnauzer became short of breath (panting rapidly), and then vomited undigested food. I finally got hydroxyzine down him (he takes for allergies, but gave it for nausea). And late he kept a small bit of dry food down. Today, he's still been acting out of character, and "sad"? He's had solid bowel movement and now the a/c is fixed. Should I be worried that he isn't himself? My lil mutt gave me sad eyes, and I had to put her down that day. =(

Yes, I would be worried Blitz hasn't been himself. Heat stroke is a deadly disease in dogs that occurs when they become overheated, and that can lead to the rapid panting and vomiting. The scary part of heat stroke is that there is a lot of internal damage done to the organs from heat stroke, such as death of liver cells, rapid heartbeat, acute kidney failure, irregular heartbeat, and blood clotting disorders among many others. I think given that he was panting rapidly and vomiting yesterday and now is acting out of character that a vet visit would be best. Just to check him over to make sure he is ok. Please take him into an ER vet: if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. I hope this helps!
