It's called the Bully Blockade, and it's aimed at keeping the pit bull population under control in Chattanooga.
"We take in over eight thousand four hundred animals a year, and 42 percent of the animals being pit bulls is a really significant number. Our goal is not to do anything like banning that breed in our community but to rather to offer spay and neuter to the public so that we can reduce the number that enter the center," says Karen Walsh, McKamey Center Executive Director.
Walsh says pit bulls are often a breed that is mis-characterized because of their size.
"Chihuahuas actually bite people an awful lot more than pit bulls do but people don't usually report those kinds of bites because there usually isn't a significant damage."
She says it's up to owners to raise their dog properly.
"Pit Bulls are a strong minded breed, so they do need a firm hand and they need people to take them and have them properly trained Often times animals bite not just out of an aggressive tendency but out of bad manners and don't know better, they haven't been taught better."
The surgery costs nothing, but time is running out to take advantage of the bully blockade.
"The Bully Block will go until we have done a thousand pit bulls and pit bull mixes in the community and right now we are right around 800. The surgery is free. We do require that you have a rabies vaccination. If you have not already had your pet vaccinated for rabies, you can do it here for ten dollars."
If you'd like to sign your pit bull up for the free procedure, you can call the McKamey appointment hotline at 305-6502. Surgeries are scheduled at the Center Wednesday through Saturday
