My Max has this...He goes into a breathing attacks...The vet says it is like asthma in humans...He seems to get them more often when he gets excited or if the weather is really cold/hot. The vet said to keep his weight down and make sure he gets enough excersise. He will be 3 in May, he has had these attacks since the day I brought him home. Other than the occasional attack he is very healthy.
I would talk to your vet they can explain it alot better than I can. |
