my beagle sometimes starts breathing/gasping quickly almost as if he was choking or gasping for air from asthma. this doesn't happen all the time but it happens occasionally. we used to live in a basement apartment and i thought that the air was the reason that he was choking. we have moved to a second floor apartment since then and i thought it was over but he started gasping again today and he was shivering afterwards. i was told by a friend that some dogs have "backwards breathing", where they breathe through the bottom of their mouths. does anyone have any information about this? i would really appreciate it. thanks.
