There's one at Farnell, just outside Brechin. On a Tuesday night, I think. I'll need to check it out for myself in the new year, so may see you there! There used to be one in Arbroath, but can't remember where. They were either a Wednesday or a Thursday.
I have always gone to one in Dundee, but this is because I knew the people who ran it, and was on the committee for a while. It also helped train the pup to behave in the car on longish journeys. :D
Edited to add: just noticed in your profile that you are in Dundee. There are 2. One in Broughty Ferry, at the Castle Green on a Tuesday night. And one in the Lochee area on a Monday night. This one is in a church hall, could take you there, but don't ask me the name of the street it's on

ChristineW will be better able to tell you when she comes on. ;)
