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