Why is my new puppy grinding his teeth and coughing? Is it normal?

Updated On September 23rd, 2025

Pet's info: Dog | Soft Coated Wheaten Terrier | Male | unneutered | 3 months and 17 days old | 9 lbs

Hello! I am a first time puppy owner and have a couple questions. He is a Wheaten Terrier and was born on March 18th! 1. When he closes his mouth every so often, he makes a sound like his teeth are grinding against themselves. Is that normal for a puppy? 2. He has a slight cough. One that sound like there may be something like mucus in his lungs. Is that something to be concerned about? Thank you so much for easing my concerns :)

Congratulations on your new puppy Sully! At his age, he should be starting to lose his puppy teeth so that may be where the grinding sound is coming from. Open his mouth and look very thoroughly just to make sure you don't see anything stuck in between his teeth, in his cheeks or the roof of his mouth. The coughing I would be a little more concerned about. Pets do get minor viruses and allergies. If he is completely normal otherwise, you may watch the coughing to see if it clears up on its own. If it is getting worse, take him in to see the vet. He's a cutie!
