Two neutered boys here.
Milo was nearly two when Remy came to us. Remy was 8 months.
They started playing the minute I walked in with Remy.
Over the next few days, Milo gave him a couple warning snips to set rank and they have been brothers ever since.
Remy BTW, is bigger than Milo, but that doesn't seem to matter in the pecking order.
