[SWHouston]

I can't let My Male Sneakers play. He's quite aggressive/dominant, and is somewhat aloof until another Dog approaches him. That's when it hits the fan. I do, in hopes, that there will be at some point, one/others which he will get along with, but so far, nada.

On the other hand, both My Female Becca and male puppy Ichabod will get along with other Dogs quite well.

I try to be very conscious of my guys personalities, and think that's the key to associations/play. It's just a trial an error issue, you have to permit or not, according to the individual.
