Why is my dog panting so much, even when she's not hot or active?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | unspayed | 1 year and 5 months old | 20 lbs

My one year old girl dog, lhasa apso-pomeranian, Leona, has been panting a lot, more than normal. She started before the temperature went up in Chicago. I had assumed she was panting a lot because she was in her time of "needs". I also have a shih tzu, Tootsie, and she never panted as much as Leona. Last night I turned on the air conditioning to see if she got better and also groomed her because she had a lot of hair, all to try to figure out what could be wrong with her.

I can understand your concern about Leona's increased panting. As you know, dogs can pant for a ton of different reasons. Some of these can include behavioral issues, such as anxiety, or medical problems, such as heart or lung diseases, heat stroke (unlikely in this case, I understand), or pain from an injury or arthritis. I'm glad that you've tried to actively cool Leona by using the air conditioner and by grooming her. Since it doesn't sound like that's changed her panting, I think it would be best to take her to the vet for a full physical exam. Your vet will be able to listen to her heart and lungs, and check her for sources of pain. It's really important to rule out any medical causes of this excessive panting, as some can be quite serious. If medical issues have been ruled out, your vet will be able to discuss possible causes and treatments of anxiety. I hope this helps and that all goes well!
