Can I purchase a replacement for the magnet. My dog has destroyed three so far. The flap is good, but magnet no more.

Thank you for your question! Regrettably, the magnet for the flap is not available for individual purchase as it is partially molded into the flap itself. Replacing the magnet would mean the entire flap needs to be replaced. If your pup has a tendency to chew on the flap, we recommend applying a bitter spray or powder to the flap to help deter future damage.
