Frequently asked
When is heavy panting an emergency?
If it comes with heat exposure, drooling, weakness, collapse, a bloated belly, or pale/blue gums, treat it as an emergency — heatstroke and bloat are life-threatening.
Why is my dog panting at rest?
Panting with no obvious heat or exercise can indicate pain, stress, or a heart/respiratory problem. If it's persistent or your dog seems unwell, see a vet.
