Anyone know whereto get a chew-proof crate pad and/or Crate Cover? The poodles like to pull stuff into their crates, or chew on the drywall which usually ends up with me pulling the crates into the middle of the room before I leave for the day. Was wondering is anyone has ideas on crate covers that could go around but be chew-proof? Also chew-proof pad to put into Lincolns crate. Thank you!
