MARTINEZ (CBS SF) — A Chihuahua that was rescued from atop a median barrier on Interstate 680 in Walnut Creek by a California Highway Patrol Officer Friday will have a few more days of tests before possibly being put up for adoption.

A spokeswoman for the Contra Costa Animal Services shelter in Martinez said the 2-year-old female Chihuahua was given an initial examination which determined she was relatively healthy.

The dog did have some fleas and was found to be very timid, according to Heather at the Martinez shelter. The Chihuahua also was growling and biting during the exam, said Heather.

The dog, which some have some dubbed ‘Freeway,’ had no tags and was not micro-chipped, according to the shelter.

On Thursday, the Chihuahua will have a review by the shelter manager which will include a temperament test to see if the dog is eligible for adoption.

Once the dog is cleared for adoption, interested parties can indicate their interest with the shelter beginning at 11 a.m. on the 15th.

The shelter spokeswoman said an unidentified person who the spokeswoman said was the first to spot the dog on the freeway has already indicated interest and will have priority if the rightful owner does not come forward.

The officer who stopped to rescue the dog after the CHP received calls about the dog running in traffic, Officer Alex Edmon, told the L.A. Times his wife asked if they could adopt the dog, but he said they own 2 100-pound dogs already so it would not happen.
