Tom Vick and his wife Diane own six dogs. When one of them, a boxer, attacked a smaller cocker spaniel the couple jumped in to stop it.
That’s when the boxer turned on the couple and began attacking them.
Diane was able to call 911 after the incident but Tom died at a hospital. Diane survived but had significant injuries.
Bullhead City Arizona Mayor Jack Hakim told AZCentral.com "we've had dog bites before but never something like this."
He also pointed out the couple is well known and respected in the town.
"It's very sad for us in Bullhead City. She was former mayor and he was a prominent high school teacher at Mohave High School. We’re just grateful that at least one of them was able to survive."
ABC 15 in Phoenix reports the dogs are in the custody of animal control.
