Get Your Dog Care Questions Answered by Experts
I'm sorry to hear that your Nessa is not feeling well. The heavy breathing has be concerned and may signal pain or an inability to properly oxygenate her tissues resulting in an increased respiratory rate and/or effort. Are her gums pale or white? Is she lethargic or painful? What kind of dog is she?
If she is pale or painful, I recommend taking her to the nearest emergency vet as she may be seriously ill or at the least in need of pain medication to help ease her discomfort. If she is nice and pink and not painful, and the only thing different is her appetite then I recommend taking her to your vet tomorrow to be evaluated. I recommend a chemistry panel and CBC be performed to look for causes decreased appetite.
I hope this answers your question tonight. If you have further concerns I can address, please let me know.
I'm glad that she seems comfortable. depending on how pale she is she may be normal or there may be an issue. If she is otherwise comfortable and able to rest, then she is likely not in distress and you can make an appointment to see your veterinarian this week. if she is unable to get comfortable, seems lethargic, appears to be concentrating on her breathing, is breathing fast with her mouth closed (so not just regular panting but actually working to move air) or becomes more pale than she is now, she should ideally be evaluated by an emergency veterinarian tonight.
Lots of things can cause panting and loss of appetite and the two may or may not be related but only a hands on exam with a veterinarian can determine if additional intervention or diagnostics are necessary.
