Hey there, I think a pen like this is fine for a dog and dog training - just be sure pup can't jump out!
They are sold at most pet stores, or you can find second hand ones in your area I'm sure - but I can't provide much more help than this! Hope you find one!
I just want to clarify that puporse of play pens are different from that of crates. I just visited Petco website and they have collapsable pens and more sturdy ones as well. Can be used both indoor and outdoor.
The collapsable ones are good to confine your pup when you are gone but only when he is very small. When he gets like 4-5 month old, he can push it around or jump over it.
If you really want to "crate" train him, you will need to find a plastic or wire crate.
You can find pens and crates by googling "dog play pen" or "dog crate".
This link just shows some typical choices of crates and kennels and carriers. Its hard for anyone to point you where to go specifically because we're not where you are, and we don't know whats around!
