This is a link to a 26 page guide to constructing successful "Pet Friendly ordinances".
It is well done and much needed. If you find your local community thinking about changing any of the local pet ordinances- then you need to print this out and go meet with your local folks.

These are some useful tools. GOOD LUCK
