POSITIVE REINFORCEMENT: Tethers get your dog out of his crate and with you while still under control as she learns how to behave! A dog tether is not a punishment. It is a training tool for safety and management in the home. When tethering is used with positive reinforcement, it can be very effective in the success of your dog training program. 4 FEET OR 6 FEET, WHICH TO GET It depends on where you plan to tether your pup and how much you want them to roam. Can they get tangled around something nearby Does she need more length to see you or less length to keep her from wandering It's up to you. GOOD AND BAD TETHERING OPTIONS: Generally, it should be sturdy, durable, and stationary without anything nearby to get tangled in. The foot of a bed or table (if they can't get scratched) are good. Lamps and chairs can fall over, so they're bad. If you need to get creative, a roll of duct tape, packing tape, or toilet paper on one side of a closed door with the tether going underneath works well. SUPERVISION HIGHLY RECOMMENDED: A short tether used as a tie out can be scary and even dangerous for a dog without supervision.
