Coughing

I, too, thought at first there may be something stuck. I've had a look but couldn't see anything and it seems to start more after initial exertion (rather than sustained running - didn't cough at all when out for a walk). Will keep an eye and thought if not improved in 48hrs will go to vet. He's one of Strider and Summer's June 07 litter (litter sister of Stella) so interesting that Strider is also very lean. It might prove to just be his build. He also seems to be shedding his winter/puppyish coat and developing a sleeker look all round! A lean, mean, non-stop running machine!!!!!!
