These easy to make colorful rope toys are great for any size dog. Just scale up or down the diameter of the rope to fit your dog, 1/4" for small dogs or 3/8" for large dogs. Directions given are for a basic toss/tug toy pictured below. Pictured are several variations based on the basic knot that can be created with a little practice and creativity.
Step 1: Finding center of two lengths of rope
Start with two equal lengths of rope, I recommend no shorter than 5' each length. Find the middle of each length by folding the rope in half and lining up the cut ends.
