PARKER COUNTY -- Tips from outraged citizens led deputies to the owner of a dog that was found shot dead by the side of a rural Parker County road early Wednesday morning.

Tammy Green Douglas, who celebrated her 44th birthday on Friday, was jailed early Sunday morning on charges of animal cruelty. An affidavit said Douglas confessed to the crime.

She was freed after posting $3,000 bond Sunday afternoon.

The dead dog, described in legal documents as a four-year-old brown Heeler/Shepherd mix named Aowa, was found in a cage along Raley Road six miles southeast of Springtown with 10 newborn puppies covered in their mother's blood suckling for milk.

Aowa had been shot in the head with a 9 mm handgun.

Investigators were led to Douglas by a tipster who showed them a text message in which she allegedly boasted about the shooting. 'I did what I did and I would do it again if need be.'

It was a school bus filled with Springtown students that came across the dead dog and puppies Wednesday morning.

Shelby Honeycut, 15, said he was on board that bus.

'I've never really seen something like that before,' he said. 'Why would you do something to a poor dog like this?'

According to an affidavit filed in connection with the case, Douglas acted out of revenge because Aowa had killed another dog that got too close to her litter.

'To a normal, caring human, this is an incomprehensible act,' Sheriff Larry Fowler said in a written statement. 'I can't imagine what the suspect thought these puppies did in order to warrant her actions. Animal cruelty can never be justified.'

A $7,000 reward was established for the arrest and conviction of the person responsible for Aowa's violent death.

The surviving puppies were taken in by the Angels and Outlaws Second Chance Bully Ranch in Hico, where they were accepted by two other nursing dogs.
