Hello, we specialize in leather products, but we also carry products made from other materials. We currently are selling leather dog collars and leashes, including English Bridle leather, adult, plus size and children leather belts which include English Bridle as well. Our collars can fit small dogs up to extra large ones. Martingale is also offered from our store. We offer spikes and spots on some of our collars- we have pictures of these in our store. Also, we sell nylon horse and dog leads/ leashes. Cat collars are also sold in our store at a reasonable price. Most of our products come with a free brass tag and all products include free embossing.
