I have a mesh playpen for when I bring my pup home on the 14th...it seems pretty sturdy but it hasn't been properly tested yet. Lol The pen is built just like the ones lovespandp has links to zippered cover and all and is "hooked" to her crate.
if you decide to get one of those definitely shop around I got mine at Burlington's for $30 when it retails between $60-$70 elsewhere.
Or check out ebay/amazon pricing is way better for the same products you would buy from a pet store plus free shipping!
