You may choose to wean your dog from needing a crate in the future. If that happens, you could donate or sell the crate to BC rescue or Seattle Purebred Dog Rescue - we always need crates. Purchasing secondhand from ads in the newspaper is a good possibility, as well. You probably can borrow one from Border Collie Rescue, if needed. A little added canned dog food may add interest for a dog with discriminating tastes and poor appetite.
Every dog needs a properly fitting collar and a quality leash.
Once strongly bonded, the risk of escape is minimized. Your leash should have a strong, spring-loaded snap. Leather is nicer on your hands than nylon, especially for any dog that pulls a lot. Flexi-Leads are wonderful, too. Choose one at least 26' in length and with an appropriate weight allowance.
