So, I've been planning on making Bentley a pen but I've noticed lately that he can jump pretty high.
How tall do you think would be safe through adulthood so that he can't jump over it?
Yeah. Bentley can jump even higher. For being less than 4 months old and around 10 lbs (we'll find out exactly at his vet visit this Saturday) he can jump close to 4' vertically. But I'm not sure about a forward leap.
I'm thinking I'm going to have to have some type of removal or netting for when I'm not home. I plan to build a new "crate" attached to a pen for a total of a little over 28 square feet of room for him in an L shape (6.5 of that is actual "crate" which will just be a sectioned off area with a bed). So he has room to move when no one is home.
We had to build a 6' wall out of wood to contain Uma, and she still escaped all the time. I wasn't even mad, it was very impressive. Wally just ran through the baby gate when he got big enough, he's like the Koolaid Man.
