Our girl, Belle, 8 Yrs old. just gave us a mighty scare. She became very rigid, tongue hanging out and blue, trying to breath and snorting. This went on for about a minute, then she calmed down and is just breathing heavily. I witnessed a mild version of this in the past four days-becoming rigid and staring. We are very worried and will check with vet as soon as possible. Can you give us some clue as to what we are dealing with. We have another bully, but have never seen this behavior. Many thanks.
