u know, i wondered whether he was having you at it regarding the coughing etc, as iv heard it several times before. my grey,poppy," got kennel cough" at the same time as my dogs a couple of years back,which my vet found hysterical when he saw it on facebook

.
i take it he has just had a ho at his old injury again? its hard to know what to do cos the collar will let it heal, but then hes going thru the stress of it which isnt easy either.
bless that little guy hes been thru the mill hasnt he.
