We have a very large dog crate for sale. Measures 48 inches deep, 32 inches tall and 30 inches wide. Kong brand, comes with plastic liner, and a separator for inside.
We purchased used, but it's bigger than we need, so we purchased a smaller one. It's in very good shape (couple of slightly bent bars), folds for travel or storage.
$40 obo (just trying to recover the cost of buying the smaller)
