Hermann recently lost his 10-year-old Beagle Sam.
"As sweet a dog as you ever met, I never even heard him growl at another creature," he said.
Hermann had hired a dog walker to take Sam on his daily walks while he was out of the country.
One day he received an urgent message from the dog walker letting him know Sam had been killed.
"They were on Sam," said Hermann, "She said she barely had anytime to react and the one dog killed Sam right there."
The dog walker explained to Hermann she was locking up the house to take Sam on his morning walk, when two large dogs attacked him.
"It was an empty house when I got home," said Hermann.
He said after talking to witnesses he quickly realized which dog had killed Sam.
"I realized that the dog that had killed Sam, I had had a confrontation with a couple of months ago," said Hermann.
He said he was taking Sam on their nightly walk and the same dog snarled at Sam and launched at his neck.
"I knew what house the dog had come from," he said, "I banged on the front door and I said, 'Is this your dog? It just attacked my dog."
"Of course these low-lifes had no apology, no nothing."
We spoke with the Lubbock Animal Shelter who said it's always best to report an aggressive dog.
"Pick up what we call a 'dangerous dog affidavit' fill it out, get it notarized, get it back to us and then within 10 days we will set the hearing date."
Even though witnesses are filling out these affidavits for Sam, Hermann said it's too late.
"Because I didn't take care of business that night, my little buddy's gone," said Hermann.
The upcoming trial will determine whether or not the dog that killed Sam is in fact aggressive.
If it is determine to be so, then there are a number of options from euthanizing the aggressive animal to requiring its owners to keep it in a special shelter, to having to keep the dog muzzled.
