Hmmm - My first instinct would be to ask my vet for suggestions.
My second instinct would be to ask people I knew at pet stores etc.
My third instinct might be to place an ad on a local site (for a dog playdate) in your area or craigslist - kijiji etc in your area. If I did choose this option....I'd probably want to meet the owner and dog WITHOUT my dog the first time in a public place like a park. These internet encounters do have some risks so if you are female I might request a female dog owner.(since some men are creeps, lol)
Hope that may help.
