I have 2 dogs and am bringing home a new puppy in a month. The puppy will, of course, get dewormings. My dogs are on Trifexis. A new vet says we should have our current dogs' stools tested for parasites before the puppy comes home. Is this overkill given that they are on Trifexis and the puppy will get dewormed?

Personally I would be satisfied that things are well under control with your use of trifexis. I think if you are giving it every month it is unlikely your dogs will have an issue. Maybe your vet is worried about resistance and wants to super safe. At the end if the day it is completely up to you what gets done, but it sounds like you are already a very responsible owner.
