Im sorry for your loss, I lost 3 pigs that way. My solution was get rid of the dogs and keep the pigs. But hey thats just me. I even had my pigs in my room and baby gate at the bottom of the stairs and the dog still got into the room... So if the dog wants in its getting in! If you want to use a wood frame just have the frame on the outside of the grids that way the pig cant chew, pee wont soak in. Is there a way you can have it on a table? What kind of dog do you have just curois. Mine were husky mixes GONE NOW and im never getting northern breeds again!
now I have a rottweiler. The best dog I have ever had in my whole life!
