About LOGAN
Who is Joshua Horwitz?
A couple years ago , he got lucky and landed an apprenticeship at Art of the Dog Canine Academy in Denver . Over time he went from apprentice to lead trainer, helping lead the team every day and helping other trainers get better at what they do. Now he’s at Sit Happens.
Joshua is pretty good at reading both dogs and people, so he can usually tell what’s going on and adjust without making it complicated. He doesn’t try to sound like an expert he just keeps things consistent and focuses on what actually works and makes owners lives easier.
When he’s not training he rides his motorcycle through the mountains, does kickboxing, hikes, works with his own dogs, and cooks.
