My bun goes nuts over these weird colored loofah chews I found at Petco, but everything else I get for him (aside from spare cardboard I toss into his pen, which he seems to decide on a whim whether he likes or not) gets totally ignored, especially wood chews. Go figure. I think he's attracted to colorful chew toys, because he does seem to like the wooden chew toys that are brightly colored. I feel like there's no way all that coloring is good for him but he likes it. Any other picky chewers out there? Recommendations? Thoughts?
