Here is a video clip of one of my dogs, Tovah and Clover meeting last weekend. This is from my facebook site.
The dogs and Clover see each other through the gates everyday and are rewarded. The dogs are taught downs. We've been doing this for a few months. I knew Tovah would be fine with her, so I had her on leash and will for some time when she is with Clover, mostly because she wants to play--has pawed Clover's head, play bowed etc. Tovah is used to playing with dogs of all sizes--some as small as "snorkies" and dachshunds, and she is gentle. As you can see Clover decides she wants to she wants to check my shoe out, the leash, etc. LOL
Anyway, it's all a gradual process.
Please ignore the taping. I'm still getting used to this handycam.
