A Salt Lake County sheriff's deputy shot a dog that had attacked and killed one dog and injured another Friday evening.

The dog, possibly a chow-husky mix, had attacked a small Pomeranian owned by Fred Pike, 12600 S. 2314 West, a sheriff's spokesman said. The Pomeranian was in its yard when it was attacked."Apparently, the chow picked the small dog up in its mouth, swung it around and bit it several times," said sheriff's Sgt. Fred Smith. The Pomeranian died as a result of its injuries.

Deputy Kerri Geer arrived at the scene about 6:30 p.m. to find Pike "extremely upset" at the death of his dog, Smith said. Riverton animal control was dispatched but did not arrive before the chow attacked another dog on the same street.

Geer attempted to intervene when the chow attacked a passing collie, but backed off when the dog turned "and appeared to threaten her," Smith said.

She shot twice, killing the chow.

When the owner of the chow was notified, Smith said she appeared satisfied that Geer had done the right thing.

Smith said the dog had apparently broken its chain earlier in the day, became aggressive and killed several chickens.

No citations were issued, but Smith said the owner of the chow may have to replace Pike's Pomeranian.
