We took an into agility class at BARK in Newton (on the Mount Ida College campus, near their veterinary school). It was great but it's outside, so they only offer classes in the late Spring/Summer/early Fall.

I've checked with the New England Dog Training Club at the Armory in Cambridge and they don't offer agility or any dog sports.

Unfortunately, I haven't found anything closer. There has been some talk of bringing some basic agility equipment to Fort Washington on Saturdays, though- if you're interested in that, email us at info@cambridgedog.org and we can start putting together a list of people who want to help make it happen. Of course, we'd need to look into any necessary permits/liability/buying equipment/etc.
