Attended a dog social under a trainer recently with our rescue to see if he wanted to make doggy friends in a controlled environment (i.e. fenced, off-lead paddock). As we thought, he's basically indifferent and more interested in toys, humans and food, ignoring the other dogs, so it confirmed that for us helpfully. However, I was surprised that the other dogs that turned up (it was a very small group) all had dog-to-dog issues and were all there to train in regards to being able to cope with even being in proximity with another dog. None of them were capable of simply having a relaxed, happy play with another dog. Half of the dogs were let off the lead to wander round and the other half had to be kept on the lead in the secure space as their owners said they had history of chasing other dogs. I had this assumption that a social would be a playful, enjoyable event. I see clearly now it's not going to be a positive experience for our dog to be in an enclosed space with reactive dogs. Would you not expect friendly, not dog-reactive dogs, at a dog social??!
