On Sunday a puggle — a pug and beagle mix — named Fred was killed by an American Staffordshire terrier named Buster.

Two more serious dog attacks have been reported in recent weeks in Alachua County, where officials passed regulations to strengthen dog laws in the wake of the September fatal attack on a small dog named Bella as she was being walked by her owner.

In both of the recent attacks, the dogs, described as pit bulls, were turned over to Alachua County Animal Services by their owners, Director Ed Williams said.

One has been euthanized. The other is being held under a 10-day rabies quarantine and will then be euthanized.

On Sunday a puggle — a pug and beagle mix — named Fred was killed by an American Staffordshire terrier named Buster.

Fred is owned by Arlene Stewart. Fred was attacked as he was being walked by Stewart’s mother in an Alachua subdivision.

Buster ran out of an unfenced yard and attacked Fred, Alachua police said. Stewart tried unsuccessfully to break up the attack and had bite wounds on both hands.

"My mother was walking Fred. I heard screaming and came running. I went flying and saw the dog pulling my dog and got right between the two dogs," Stewart said. "A lot of it is a blur other than what I did to try to get the other dog to release my dog. It was my Fred, so I got between both of them."

Gretzaly Gonzales-Torres, Buster’s owner, eventually got control of her dog and put it in the house. She told police the dog got out of the house unexpectedly when she was taking trash out the back door.

A video posted to Facebook by Realtor Henry Rabell, who was holding an open house in the neighborhood, shows Gonzales-Torres pulling Buster’s tail to try to get it away while it had the pug in its mouth.

Fred was 7 years old and was adopted by Stewart from Pug Rescue of Florida and had some medical issues that the Stewart family was helping heal. Stewart said Fred was a special dog and was named after Fred Sanford, the irascible but lovable junk man in "Sanford and Son."

"He was witty and sassy and by far the smartest dog I've ever owned. I really believe he understood English," Stewart said. "There was a squeaker toy in the shape of a pizza that he loved so he had eight pieces of pizza floating all over the place. He walked outside with a pizza and left it in the driveway. I said 'You forgot your pizza.' He turned right around, went outside, grabbed it and walked back in."

Meanwhile, on Nov. 28 a dog got out of a house and attacked the 9-year-old son of Chris Blake on Northwest 40th Avenue near Stephen Foster Elementary School. It also killed a cat. Blake said a neighboring home has motion-triggered cameras that recorded the attack.

“He got bit in the face and had a broken tooth. It was pretty bad. Nobody was around when the dog came out. The whole scene was caught on camera and as a :parent that is not something you want to see,” Blake said. “My son doesn’t want to go outside by himself anymore. We have a couple of dogs and a couple of cats that he always played with ... and now he kind of turns away. It’s a shame.”

Blake said the dog has behaved aggressively in the past.

An Animal Services report on the incident said the cat's owner was bitten trying to stop the attack. The cat was taken to a veterinarian but died.

The dog, owned by Justin Hauck, was relinquished to Animal Services and has been euthanized, Williams said. Buster has been turned over for euthanasia.

The outcry over the death of Bella as she was being walked in the Northwood Pines neighborhood by owner Linda Swinburn spurred changes by the Alachua County County Commission. The three dogs that attacked Bella had been reported for other aggressive behavior before Bella’s death but owner Nathaniel Pettiford was able to keep the dogs.

After Bella's attack, they were seized, legally declared dangerous and euthanized.

Under recent changes, Animal Services must now impound a dog that is under investigation for being dangerous unless the officer determines it is safe to leave the dog with the owner.

The fees for animal citations will increase to more closely match the city of Gainesville's. Examples include raising the fine for failing to physically control a dog from $50 to $250, and raising the fine for having a nuisance animal from $75 to $250.

The county also will close a loophole in which animal owners were given multiple first-time citations for equivalent violations.

Also, the county attorney now no longer needs approval from the commission to file a legal action.

“We’ve made all kinds of changes with regard to policy and some modifications to the code,” Williams said. “We’re trying to do a much better job.”
