We purchased this for our Havapoo who is 10 weeks old and now 3lbs  1.4 Kg. It’s a nice concept with the adjustable panels however this play pen is not worth the money at all. It has thin plastic sheet panels with a wire frame and plastic 4 way hooks. It is not sturdy and our 3 pound puppy can easily move push it out of place. Don’t recommend this at all for your fur babies.
