St Bernard Panting

My 4 yo 125 lb none nurtured Bernard has been panting for a few weeks steadily. This is the second time this year this has happened. The first time the vets couldn’t figure out what the problem was. I have videos if needed.

Hello - panting usually looks the same whatever's causing it, but it can be sign of pain, overexertion, heat stroke, anxiety, heart and lung problems, thirst or breathlessness.  Any of these things can affect any breed of dog, but St Bernards are prone to certain heart problems and also certain causes of pain, so it's well worth checking out early. Your vet may listen to the heart and lungs as a starting point.
