This situation is different than the typical animal attack incident.

Authorities are going to evaluate the animal after it reportedly attacked another dog two days ago.   Yakima officials say the dog WAS a registered service animal that was exempt from the city pit bull ban.

Code enforcement officials say the dog escaped from it's home, attacked another dog, then bit three people who tried to fend it off.    Officials don't know how badly the people were bitten, but the animal will be quarantined until it can be determined if it's a threat.

The owner could lose custody of the animal if it's judged to be dangerous.   Yakima recently passed a new law allowing the breed to be used as a registered therapy or other service type of dog.  Otherwise, pit bulls are banned inside Yakima city limits.
