Holly Marie Combs is mourning a one-of-a-kind friend.
"Lost my favoritest Dog ever today. Thunder …there will never be another like you. Ever," the actress Tweeted
Sunday, sharing a photo of Thunder's worn leather collar.
The former Charmed
star rescued the pooch over a decade ago from Austin's Town Lake Animal Center
"Thank you TLAC for the best dog that ever picked me," she wrote
. "He gave me the best thirteen years a girl could get."
The actress's Twitter followers, including actress Julie Benz, left comforting messages for Combs after hearing the news – and one fan reminded her that she needs to update her last will and testament. In January, she Tweeted
that she was leaving everything to Thunder.
"If anything should happen to me, tell the authorities it was the black horse. And my estate goes to my dog Thunder. Thank u much," she wrote.
