When you see dog agility contests you know that you want to do that with your dog. You can by dog agility sets like this one from amazon: http://www.amazon.com/Kyjen-DG40100-Dog-Agility-Starter-Kit/dp/B000AAM0GW/ref=sr_1_1?ie=UTF8&qid=1378135030&sr=8-1&keywords=dog+agility
But this kit is 40 dollars and does not contain all that I wanted. This is how I decided to make a dog agility hurdle.
1. 8 nails with a big head.
2. 4 large screws.
3. 3 3/4 inch dowels.
4. Spray on gloss.
3. Yard Stick
Step 1: Measuring!
To start get 2 dowels, 8 nails, and a yard stick. Grab The dowels and put them side by side on a table where the tips are at the exact same place. Get a marker and draw a dot on both dowels that is six inches from the bottom of the dowel. Then draw three more dots on each of the dowels at 11 inches, 16 inches, and 21 inches. Make the dots in a strait line so that if you drew a line connecting them it would be completely strait.
