mine are resource guarders but they respect each others food and even when they do guard they never hurt either other because their bite inhibition is good. plus usually a little growl is enough to get the other to back off.

I feed brock in a bowl whether alki is around or not, but I always feed alki in her crate. I either toss the kibble in loose for her to scavenge, or feed her in a tricky treat ball or other work-to-eat toy. when using those I have to seperate her otherwise Brock will eat the loose kibble that falls out.
