Dog Tennis Ball Toy. This is a fun simple project for you and your friend. I'm not sure, but could be encouraged to beleive that maybe, just maybe, with the right inflection in your voice, your best friend may stick around to see the making of his or her toy. Just saying. A toy, collar and leash could be made in matching colors. As with almost all dog toys they are not made to be eaten. You do not want your dog to eat paracord. Discard the toy, ball or both if damaged, frayed or likely to be eaten by your pet. Same would go for leashes.
