We have a lurcher who we don't allow upstairs, mainly because I don't want her in my bed but also to keep her away from various toilets with bleach etc and to stop her from chewing the do togs.
When we are home she doesn't even try to go upstairs but when we leave her home alone she always manages it. We have an extra high pet gate but she can seemingly jump this (we haven't caught her red handed but she messed up our bed and ate some Xmas chocolates hidden in a wardrobe today). Training wouldn't work as she never does it when we are home!
The gate is too high to fit at the bottom of the stairs and only just fits on the second step down so an even taller gate wouldn't work. It's semi open plan upstairs so it has to fit across the top of the stairs or at a right angle next to the top post.
Does anyone have any ideas of something I can do to increase the height of the gate to act as a deterrent? I thought of plastic trellis but worried she might try to jump over and trap her legs.
Fwiw she has a crate and access to a carpeted room with her bed etc in it downstairs so there shouldn't be any need to go upstairs. I'm only ever out for a couple of hours so hopefully she's not bored- she just sleeps all day when I am home anyway!
