Note: it is never wrong to suggest that a person go to a vet. Just because one pup was ok with voice loss, does not mean the other is exactly the same. I understand that you say you will go to a vet if it persists, but it always bothers me when someone posts that in their first post. Why would it offend you if someone suggested you go to a vet?
