Tucker seems to really dislike being on a leash and collar. Iím just trying to see if a harness makes a difference, but he really doesnít understand and pulls away from me with both the collar and the harness. Itís a lot easier to quickly put on his snap collar when I need to take him out to use the bathroom than it is to put on the harness so Iíd really like for him to like his collar. Any helpful hints? Thanks so much!
