SAN DIEGO (CBS) — A Chula Vista puppy missing for six years is back with her family on Friday.

KNX 1070′s Tom Reopelle reports a microchip implanted in Cookie the chihuahua helped officials locate the owners.

Officials at the city’s animal services department say Cookie was found just a few miles from her home.

“When they called me, we were happy and crying,” said Maria Pantola, the pup’s owner. “Everybody was happy.”

Daughter Amy never thought she would see Cookie again.

“We had to go look for her through the kennels, and once we saw her, my sister called me over,” Amy said. “We both started crying.”

Cookie isn’t saying where she’s been all these years, but it’s believed she ran away from the Pantola family, was found by another family, and then eventually ran away again.
