Screened Door Pet Guard

We needed to pet-proof the screened door. I didn’t like the commercially available RV pet grates because they had poor reviews and appeared flimsy.

I settled on aluminum flattened expanded mesh. None of the local hardware stores had it so I ordered a piece from It was expensive, but they cut to size, so I didn’t have to mess with getting straight edges. The size needed for a Casita door is 20″x18.5″. The panel was $25 plus $20 for shipping. You might be able to find cheaper mesh at your local hardware store.

I painted both sides with Rusoleum Satin Black spray paint. To install the guard, I used #8 x 1/2″ long stainless sheet metal screws and washers after drilling 1/8″ holes in the door frame. It came out great and no more worries about the dog turning the screen into a “doggie door”. It also still lets air through and doesn’t get “smudgy” like plexiglass would.

That sure is a professional looking installation and very functional too.

This is a great idea we need to install for our little pups. What mesh size did you end up going with? 0.5″ or 0.75″?

0.5″ The embedded link takes you to the exact product I used.

His link automatically loads what he bought. I did same thing (from his link and dimensions) and added rubber on edges, works great.

I found the same material at Lowe’s in a 2×8 sheet, I cut it to fit, painted it, finished the edges with the trim used in tub surrounds, just glues on. Then screws on. About $10-$12 and it has been 5 years with a border collie.

Thank you for this. After the dog went through the screen I was wondering how to keep him in.
