Oliver isn't certified yet, have to wait for him to be a year old before he can take the therapy dog institute test, which is basically the same test they give for the Canine Good Citizenship certification. What I did was get onto the AKC's website and clicked the link for CGC testing evaluators and it will give you a name of someone in your area. I was lucky enough that Oliver's instructor for puppy kindergarten was the evaluator. He administered the CGC right at petsmart and it only costs $10. He told me that our local Humane society has an evaluator there for the TDI, so once he's a year (in December) then I'm going to be contacting her about testing him for the TDI. I think therapy dogs are awesome and can't wait until I can start taking him to places so people can love on him as much as he wants since he is a HUGE cuddlebug! Good luck and I hope you have as much fun with it as I am so far.
