I wrote under the post "The Cough" about the weird noises and odd breathing that Mugsy had been making. I have discovered that it was from his greenies. This mystery was solved purely by accident. He had not had his greenie for a while and the noises stopped. I didn't relate it to the greenies until I gave him one and the hacking and noises began again. I think the little pieces must get caught in his airways. He eventually gets it all down, but it's not a pretty sight and it can take days ! I had been giving them to him quite often ever since we got him at 10 weeks. I think I will only give him one again on rare occasion for a special treat.
