I Spent President’s Day Looking for My Dog — Do Identity Chips Work?

I went to visit my mom in Spokane this weekend, and I lost her dog.

My mom's dog, "Precious," is really old and is completely blind. I let her out to go pee and she got lost!

I was panicked because there was NO WAY I was climbing to the top of Idaho Hill to yell, "PRECIOUS! COME HERE PRECIOUS! WHERE ARE YOU PRECIOUS?"

Finally I found the blind dog running past the house and it was all OK.

What is the best way to find a lost dog?
