What would cause this? We adopted this dog a week ago and he still pants excessively and constantly except when asleep. This happens even when at rest and when the indoor temperature is cool.
I figured at first that he was just stressed about being with us (and he is, I know ---he has a fear of being abandoned outdoors, or behind any closed door). We are working on his fears by never leaving him outside unless we are with him, etc. but this panting doesn't seem to be getting any better.
Could it be something else?
