I am thinking of getting Roo a harness. I have walked him in his Clix car one before but its not especially helpful. I think I want one which looks friendly, ie. it doesn't look like my golden retriever is wearing a harness because he needs to be restrained/is aggressive. And I think I'd like one which I can grab the top of easily if he is being a pully brat instead of holding his collar for a few seconds. I'm looking at the Julius K9 as I know they have handles etc etc on the top but I don't really know much about other harnesses. I want to be able to hold him by the top of it if I want to and to look OK in terms of not restricting movement at all... What do you use and why please?!
