Of course I do not leave all three yorkies in the tent. The size is perfect for them to keep their bed in for overnight trips or visits to friends' homes where we might be outside and the tent screening helps them from being bitten alive by insects. And if I happen to set up the tent, like I did this evening, they choose to go in there so obviously they find it very suitable and lots of fun.
We also own the playpen you have -- we used to keep our two yorkies in there for overnight trips. With a third dog who likes to jump, I had to find something larger and a maybe one with a cover. I also would not keep one yorkie in the playpen all day long -- therefore, in my opinion, the tent would be a better option for Buddy.
I posted the video to help the lady decide if it were right for Buddy -- she had concerns about the security of the tent. I put the other items inside the tent so she would get an idea of the size of the tent for her one dog Buddy.
And to the poster who called me thoughtful - thank you - I did come home and set the tent up and place those items inside before even taking my shoes off from work in order to help the OP decide if the product was right for Buddy
as I said that I would last night when I initially responded.
