I'm at my wits end and need some ideas for a solution. I have two PetSafe pet doors size large. One is a single flap in a storm door leaving an enclosed porch and the other is a weather insulated model in an exterior door accessing the enclosed porch.The problem I have is the dogs keep getting the magnets off the bottom of the flaps and the magnets are not sold separately from replacement flaps. Eventually they chew the corners on the flaps too. I have yet to catch them in the act, just the aftermath.Replacement flaps are $42 each at Lowes, a bit cheaper on Amazon. I bit the bullet and ordered a couple off-brand flaps at the bargain price of $27 each. I bought some of that stop-nail-bite polish and coated the bottoms/magnets on each. 4 hours later, the magnet is missing and the flap won't seal shut.My porch gets a good bit of wind from the north and cold air blows right through both dog doors and into the house when the magnets aren't there to engage. I tried adding some silicone door sweep with adhesive to go around the door but that impedes the flap opening and closing properly.I need some ideas guys. I can't keep throwing away money on these flaps.This is the pet door on the exterior entry door. https://ift.tt/2Vx2qus storm door takes the exact same flap part number. via /r/DIY https://ift.tt/3coBMdo
