The ball traction toy
This tutorial very easy to do, will delight your four-legged companion.
You will need
a sleeve or trouser leg (I took a jeans because it is more resistant)
a tennis ball (prefer dog adapted ball, they will be better for their teeth)
How to do
Open the sleeve (or trouser leg)
Tie a knot at one end
Place the ball in the center and close the fabric. Then made a knot close to the ball to avoid having it get out. If you have enough fabric, you can repeat the operation and add 2 or 3 balls.
It is ready! Have fun!!
