Why would our 2 yr old + rotti cough very loudly, like a child with a chest cold,
when she ran for a stick this morning? It was a hard, fast run. She coughed twice, then it subsided. She has not done this before. She was breathing hard. She has a short snout, and our vet told us when she was 4 mos old that there could be some breathing issues, although nothing major expected.
I have read everything from 'don't worry about it', to 'lung cancer'.
