I recently adopted a teacup terrier due to him having a stress cough. (It’s an attention thing as he developed it when the previous owners had their baby) anyway he had blood tests and heart scans and there is nothing wrong with him. He just makes these noises like a pig. It’s so loud. Is there anything I can do to help him or stop this behaviour. I hate seeing him do it it sounds painful and I just want him to be a happy pup

Any advice a all?
