Simply put: the best there is. I know that’s just my opinion, but I have had dogs in all the big cities in California for the past 15+ years — and I have hired *lots* of dog walkers. I’ve only had bad experiences with a few — and the rest have been really good. But Mt Tam takes it to another level. Erin and Dave set the bar really high — and it shows in all the amazing walkers they hire. They simply treat every dog like it’s their own dog — and it shows every day in everything they do. You can’t put a price tag on that (and by the way, their prices are totally reasonable, too!).
