Query: This product cannot completely prevent pets from passing through.

"This product cannot completely prevent pets from passing through." This is not only my opinion, but a quote directly from the instruction manual. My 20# dog pushed it out of his way in a short time. It was mounted on a tile floor.I tried adjusting the length so the dog could not move it but as long as the dog had access to the sides, he could move it. The only way that I could contain my dog with this gate would be to anchor it to the woodwork.Amazon and the manufacturer need to make this ("This product cannot completely prevent pets from passing through") known on the product description page BEFORE you order it.
