I’m Lisa Beach, the proud human companion of Mack. He literally showed up at my front door about 7 years ago. He had most likely been dumped - he had a collar (but no tags) and he wasn’t chipped. I did all the things one does to find previous owners but to no avail. I was overjoyed to “unofficially“ adopt him after a few weeks of looking. He’s a good buddy!
Mack sometimes has leash aggression issues (we’ve worked with a trainer) so if we avoid you when out walking, it’s because I can tell he’s feeling fearful.
He has done well off leash with other dogs - but he tends to mind his own business and isn’t very playful. I’d be happy to give a play date a try and see how he does.
