I bought l-theanine from a local natural food store. Just be sure not to buy chewables, which usually contain Xylitol.
This is the lactium I bought for Toby. I gave him 1 per day.

In some areas you can get Zylkene, which is specifically for dogs, but its literally 3 times the cost. 1 month work is $80.00! Its available in the UK as well as Canada, not sure about the US though.
If you do a little research you'll see that Zylkene and Lactium are the same thing.
