My Maltese Finn came to live with me as a puppy last winter. Since we weren’t taking long walks and mainly going outside to use the bathroom, I started out with a regular leash. As he got older and we started walking more, I got him a nice harness. It seems to fit well, but he doesn’t come to me when I get it out. If I grab the old leash, he comes right away and I can switch to the harness. Has anyone else experienced this? He does seem to know the harness is for going out.
