Hi Everyone. So my 5 month old is doing pretty well with housebreaking. He's being crate trained now, has stopped peeing in the crate and he definitely "gets it". This past week he has seemingly regressed....he's starting to lift his leg all over the house, and just minutes after he's gone outside.
Is he starting to mark???? I do have two older large dogs both are neutered and they get along great. If this is the beginning of marking, is it too early to have him neutered now instead of waiting till he's six months old????
