What Makes A Dog Door Heavy Duty, Strong or Chew Proof?
Heavy duty and strong dog doors are usually made of stronger metal materials like a heavier metal frame, instead of for example a plastic or thinner frame that might come with regular pet doors.
Chew proof dog doors will come with a flap that is hard, and therefore chewers will be discouraged to try chew it.
Softer vinyl flaps might be easier for chewing dogs to get a hold of.
