MAGNOLIA, Texas – A dog survives an attack by a pack of coyotes thanks to a neighbor’s dog. Now, both dog owners talked about the dangerous situation and the bond between their dogs, even before the attack. As far as neighborhood pals are concerned, Bella and the 8-year-old border collie, Tasa, are positively inseparable. “If she sees her out in the yard she is whining to go play with her,” said Bella’s owner, Michael Cobb. But on Thanksgiving Day, Bella became more than a friend, she turned into a guard dog.
