There are a million to choose from. We mostly use our dog's kibble saving the "good stuff" for more challenging moments or for rewarding our dog's increased efforts. You can spend hundreds on rewards, but nothing beats this. Slice the dog lengthwise (twice for the jumbo franks), then chop down. Perfect size, reliably delicious to the dog, available basically everywhere and easy.
We do prefer solid crates instead of wire. They keep in the hair, the mess and most importantly they keep in the dog. Wire crates...well they don't. What they ARE good for though is ventilation. Have a dog that is breaking out of everything? Get a Ruffland Kennel. They are more more expensive than your run of the mill plastic crate BUT they will contain your dog. They are also our top choice when it comes to having a safe crate to transport your dog in the vehicle. You can order them online or purchase them at Cabela's.
If you are looking for a slip lead, this is your leash. It's versatile and can be used as a regular leash as well as a comfortable and effective slip lead. This is the only leash that we have found that is a leash and a slip lead all in one. We LOVE them!
