I make sure that Pippin gets gaurdian time with his bunnies a few times a week...Last night we added Sheba to the mix...All did well except when Sheba got a little too sniffy with Jack Bunny, then Pippin gave her a definite BACK OFF!!...We don't allow Sam with Pippin anywhere near the bunnies...That is always a fight...Sam has really shown little interest in gaurding anything but the doors in the house & the babygate so Sam's fine with this.
edited to add I LOVE the 3rd & 4th pic...It looks like Pippin is saying, "O.k..That's MY bunny Sheba but you can sniff it a little...JUST a little!"
