Help save my dogs from Broward County dog law!

A neighbor claims my 2 dogs "Chopper and Chuleta" attacked and killed his cat off both our properties. No one else besides him claims to have seen the dogs attacking the cats, and he supposedly buried the cat the next day at his job 20 miles away. He called broward county animal control a week later with his story. With no witness, no cat, picture of cat, proof of existence of cat, vet examination of a cat, etc.. the county took my dogs and are trying to euthanize them under the "Dangerous Dog Law". Please help by signing the petition as the county and Tim Keller (lead investigator at animal control) are out of control and have a desire to euthanize any and all dogs. Murderers get fair trials, but the county is saying guilty until dead for the dogs!!!!! Lets stop them!!!!
