I would probably recommend getting a taller crate as Boston Terriers get somewhat bigger than yorkies. I really like our expen. We kept Hot Rod's crate, food, water and pad in there. It was really a relief for me since I was working irregular hours. I knew that he had everything he needed if I didn't get home right away.
Hubby purchased the expen so I don't know what brand it is but I think that it might be the one you are looking at. It is gold mesh. Mine is 2' by 2' and there are 8 panels. I can add to it also. Good luck.
