So I have not been posting in a while BUT everything is fabulous... sorta.
Last week, Chase was out with another family member and slipped his collar. Of course he was also pulling and I did not want that happeneing again so I bought a gentle leader! It is amazing and immediately stopped/reduced his pulling. Especially with all this ice I could slip on!
(The color of it is fawn!)
So to sum it all up, the gentle leader is a great safe way to prevent your dog from pulling. It does not limit the use of their mouth as you can tell in the pictures.
