How long can your dog play before he gets breathless? My Buddy seems to pant after only aobut 10.... or maybe 15 minutes, of off and on running...not continous running, just off and on short bursts will get Mr. Buddy breathless........sometimes, 10 minutes of even in-the-house romping does it. (well, sometimes even that is kinda vigorous at times..) Buddy does kinda go over to his bed or some kinda slightly 'away' area, like indicating he wants to rest....then, catches his breath after a while, and then, sometimes he is right back at it again. Othertimes, he kinda takes a nap then... ...is this normal? An Australian shepherd that i dog-sit is very much the same way, about 10 minutes, maybe 15 minutes......the Australian does not stop though, and will keep running around til i really worry about him and make him stop...that dog's vet says the dog is perfectly fine. My Buddy's vet says same thing about Buddy.... SO HOW LONG CAN YOUR DOG PLAY/RUN AROUND BEFORE HE/SHE IS WINDED?
