If the hardware wire is well applied, even sandwiched between boards would be better, it should do just fine. I've had more simple hardware wire construction rabbit cages get knocked down and torn open by a 35 lb dog before...they just pounce on them over and over, crushing the cage until the wire pulls apart at a seam or metal rings open up along those seams and they can get a nose in there to snatch a rabbit.
Someone told me once that the best way to test a pen (chicken, rabbit, etc) was to feed your dog a hotdog - then let him see you put the hotdog in the pen. Lock it and walk away. Come back half hour later, if the hotdog is still in the pen, it's 'generally' predator proof.
Right! And even if the hutch proved to be dog-proof, you'll be left with a less than attractive pen for your rabbit.
