On initial review I stated “Upfront I have not opened the item as of yet. I bought as I’m getting a puppy soon and want o be prepared. I did a lot of research and the “pen” was the best for my situation at an excellent price. It was delivered quickly and it Is well boxed and I was able to move it to my basement easily for storage. Can’t wait to set up initially for indoor use and later in my yard, you don’t even need a yard to set up outside. Puppy/small to large did will be grateful.” Having used it indoors through the winter to secure my dog when in my home trying to get something done it worked a treat, now he much bigger and better behaved in the house. Moved it outside and it’s fantastic as it secures my yard (other three areas are fenced) and he can be outside alone. Best dog sitter ever, just need regular check ins to ensure he’s not tearing the garden up.
