When I brought Max back in the late afternoon, Sam immediately behaved as though Max was a stranger, without even getting close enough to sniff him.
Two days later, he's still spitting at Max and even making attack runs towards him. I don't think any blood has been drawn but who knows what goes on during the night when they are on their own.
I just hope this isn't going to take another 3 months to resolve. It's just too distressing for us.

Forgive me for sounding over enthusiastic on your stressful times.
I find adorable Max trying to conquest Sam's friendship again, and Sam's expressing his upsetting over the brother's disappearing/reappearing act. Maybe it will keep Max from wandering too far from home.
