So my babies, they are HORRIBLE when it comes to walking on a leash. Absolutely horrid! They jump, pull, bite the leash, they do anything but walk on the leash the right way. Yes, yes, these are bad pictures. They had just got back from a walk and I couldn't get them to sit still for two seconds.
So I invested in one of these. They are $25 each but so worth the money for me. The "Coastal Halti Headcollar" from Pet Co. It is connected around their snout, so when they start acting up, tug on the leash a little, it pulls their snout to one side, and they dont like it. They start acting good then :)
