Summer, how much did you pay for your doggy pen (if you don't mind me asking). There are a lot of options and I'm not sure how much I need to spend to ensure she can't just knock it down
If I remember correctly, I got it in the sale at pets at home and it was reduced from ÂĢ70. It's the big one though, rather than the one for smaller breeds, but I wanted her to have the most space possible. My friend borrowed it when her dog had 7 puppies and it held firm, it was pretty heavy.
It might be worth checking gum tree/eBay because a lot of people get rid of quality stuff after very little use. I paid full price for a crate, then bought a second hand one exactly the same for ÂĢ15! I kept one at work and one at home
