You should take her to the vet. These symtoms sound like a UTI (infection). If you cannot afford a vet check, you can take a urine sample to the vet, and they can give antibiotics if that is the problem. But I strongly suggest taking the dog down there and get checked out. It is always better to be more safe than sorry.
Good luck, I hope she turns out OK.
Animals, what animals? My children just have alot of hair!
My chow chow is turning 13 years old and I have noticed that he is also leaking urine. When he is outside, rather than lifting up his legs to pee he is just spraying his urine along the pavement. :( I am not sure what I should do about this. He is not neutered.
I experienced this exact same issue with my last Chow when she was about 14. She had Cushing's Disease for 5 years and it had just taken a hard toll on her body. Please get your beloved Chow Chow checked out, perhaps the vet can help. With my poor baby girl, she finally let me know it was time for her to jump the rainbow, and I let her go. It was one of the hardest things to do, but as we sat on the front porch with her (the vet came to my home to put her to sleep) I could sense peace for her when she was gone. I wish you both nothing but the best, and hope that the vet can find an answer. As I'm sure you know 12-14 is a long life for a Chow Chow, but only you and your dog can tell when it's time to let go. The 'panting' if it seems to be for no reason, your dog is mostly likely in pain. Chows never really let you know how much pain they can bare, but panting is a indication that they are uncomfortabel.
