When I first rescued Gizmo at nine weeks, and for the first couple months, if he played too hard he would cough for a second. I was freaked out because I had a friend that had a yorkie die from CT, so I took him to the vet and they did X-rays and everything of his trachea, which came out looking perfect. The vet explained to me that with Yorkie puppies they have very small lungs, so if they over play its harder for them to breathe as their lungs can only hold so much air, and as they get older, their. Lungs grow and they eventually grow out of it. Sure enough, where as when Gizmo was younger he did it a lot the more he would run and play, but now at 7 months old he only does it occasionally. So with a pup that young this could also be causing the problem, small lungs that just need to grow and get more used to taking in more air the more he plays. |
