My French Bulldog Started Having Heavy Panting Spells. He Pants Very Heavy With His Ears Back, Heart Rate Is Very Fast, Like He Just Ran For 10 Minutes. Not Overly Warm, Looks Very Uncomfortable. Then Seems O.k For A While, Episodes This Evening?

Is it hot in the house? Any airway problems diagnosed? An heart problems diagnosed? I'd probably see if I could get him in and checked out today just in case. They can have so many issues and can be surprisingly sensitive. Is your vet a Frenchie/Bully vet? That can help tremendously. :-)
