Query: Best item for an energetic puppy!

This pen is the best investment I have made for my puppy! I have a puggle and she is VERY energetic, so I felt bad leaving her in her crate while I went to work. So I bought this pen and she can now stay in it all day long! It is very sturdy and can go inside and out (it has stakes for outside). Also you can fold it up so that it's about 5 inches wide and take it anywhere. I have recommended this to everyone I know getting a puppy and I would recommend it to you too!**Keep in mind that this is only 24" tall, but you can get the same pen in taller heights. I have a 4 month old Puggle who it is perfect for, but keep in mind the breed you have because the bigger the dog the taller you will need!
