PetSafe Gentle Leader Headcollar, No-Pull Dog Collar, Small Up to 25 Lb., Black

I have used a gentle leader on several dogs over the years. To me, they are the most logical and humane collars for our .canine companions. When my dog pulls to chase a squirrel or see a friendly pup, a little tug turns the dog's nose — like a horse halter. It redirects their attention. Instead of tugging on a dog's neck and damaging the esophagus. And, of course, halters are only a good choice for petite, miniature dogs — unless you are training horses to pull a plow or cart. Of course, halters teach animals to pull. So, looking at the options for dogs — the Gentle leader is a sound, intelligent choice. I do recommend putting it on your dog while eating (follow directions for fit) and giving treats so the pup can adjust to the feel of the new collar. Again, it is the nicest thing you can do to your canine companion.
