Why is my 5-month-old puppy drooling? Is it teething or vet visit?

Updated on September 23rd, 2025

Pet's info: Dog | Australian Shepherd | Male | unneutered | 5 months and 8 days old

My Australian Shepherd is 5 months old. He is drooling excessively and it's thick. He hasn't been coughing or anything, but this drooling just came on today. It is a clear mucus. He doesn't seem to be acting any differently. Should I take him to a vet? He is curious and likes to occasionally eat things he shouldn't, but he hasn't got into anything that I know of for it to cause the drooling. Should I take him to a vet, or could it be because he is teething with 2 teeth cutting through?

If Hoyt does have two teeth cutting through at the moment, then the drooling certainly can be caused by that. Without seeing him person, however, I can't say that for certain. Given that he isn't acting any differently, I would monitor him for tonight, and if the excessive drooling continues through until tomorrow, then I would have him seen by a vet for a health check. Should he start act differently and shows other signs such a vomiting and lethargy, then I would take him into a vet ASAP.
