Although this crate is aesthetically pleasing, I would not recommend it for puppies or small dogs. The spaces between the bars is too big, I could totally see my puppy getting himself stuck in them if he was trying to get out , and honestly I feared he would get his jaw stuck in one of the circles if I left him alone. I bought the large size and chose this one over other wood ones because it came with a divider and my golden retriever could grow into it. Hes 14 wks and so far I have not been able to use this crate for the intended purpose - when I can’t be around to watch him. I had a normal wire crate for my 5 year old  golden and never had these fears. And paid a fraction of the price.
