I think the pens are good for young puppies to play with their litter mates in - but for me, I prefer a crate.

We've had our for years and have had so much use out of it. All my dogs have loved their crate and classed it as a den, a place they feel safe in.

Lola always gets put in there to settle down for a nap after she's been fed. She goes in the corner on her vet bed and is asleep almost immediately (giving it welly with her snores )
