other reasons for dog panting besides heat?
my dog will randomly, out of nowhere just start to pant heavily, his tongue will fold, back slightly arched and ears back. This is never associated to heat. We could be hanging out in the evening and all of a sudden he will start this panting. I don't think it's stress because I don't see why he would be stressed, bored maybe, but not stressed. I have heard that heavy panting can be related to heart problems, could this be it? any other ideas?
btw: please don't just tell me to bring my dog to the vet, I am looking for an informative answer and if I can avoid the costs involved in getting tests done left and right by the vet, I would rather get smart feedback first. thank you
my dog is a 3yr old Boston Terrier - and again, this is NOT related to heat, I am quite aware of the body temp on dogs vs humans. This usually happens in the evening time.
