Welcome! My name is***** am a UC Davis graduate, and currently, a Medical Director of a veterinary hospital.
I am sorry to hear about this concern.
Excessive panting can be caused by:
- endocrine diseases including
(low thyroid hormone and very common in older pets)
2. Cushing’s disease
(where the body is producing excessive amounts of its own steroids from the adrenal glands and also quite common)
- A primary problem with the lungs like bronchitis, pneumonia, asthma
So, particularly high on the list would be nausea or pain. So, if unresponsive to a drug like valium, which would be used for pets with suspect seizures
, you need to get in to an emergency vet for a recheck evaluation and different medical management. Unfortunately, panting all day is definitely of higher urgency, and we don't have a good over the counter therapy in this situation.
Well worth the ER visit. Good Luck! Dr. Andy
