Hi everyone! I'm new here and signed up because my 3 year old, deaf cattle dog, whilst adorable, is proving difficult to teach any manners. He is absolutely addicted to fetch and constantly begs to be played with, placing his slobbery ball in your lap whenever going outside. I have a few hand signals to tell him no, drop it, stay, etc. However it can be difficult to communicate with him when he's not looking. Does anyone have any tips to get his attention?
