Pet Crate (Large, folding, double-door with divider) - $50

This folding crate is perfect for potty training because it comes with a divider. Our trainer suggested it and our puppy was potty trained very quickly. As our puppy grew, we would adjust the divider accordingly until he no longer needed it. We also used it to crate train him, which came in handy in certain situations (e.g., glass broke in the kitchen and he went to his crate). With a comfortable mat, the pups can use it to den whenever they feel like getting away from the family (we leave his door open). It is relatively easy to collapse, fold, and take along or store.
