Took Sampson to the vet yesterday because he was chewing on his paw. The hair in his paw was red so we thought he had injured it. Turns out that the red hair is from saliva stains due t his licking it so much. The vet told me in essence he is a thumb sucker. So it appears that every male under the age of five sucks their thumb in this house. Maybe we can get a picture of them all doing it at once. Too funny. Didn’t know dogs had the equivalent of sucking their thumbs.
