My Chihuahua is about 5 years old. We got him when he was 6 months old and he has always made this like snorting sound when he gets excited. I asked my vet when he was a puppy and he said that most of them grow out of it but he never did. What do you think is wrong with him?
It sounds like your pet has a collapsing trachea which is very common in small breed dogs. There is no effective treatment for this. You can help control the symptoms with anti-coungh medication. A chest x-ray will help with a diagnosis. Vetcare
