I went to visit my son Terry and a chance to visit with Brownie.
All Terry has say is "Get the squirrel"...and she is up the tree.
No squirrel in sight, but she doesn't care.
(And Coleen, this is a grand old oak.)

Note from Brownie's "Mom", Terri:

Brownie's "Mom" here: Terry taught her to do this from a pup on. We joke that she is half cat. She is fearless and will jump down from 7 feet up! She's nine now and doesn't do all this as often though. She trees anything and everything that climbs a tree - squirrels, cats, opossums, raccoons, etc. (But she leaves our chickens alone!) She's a Blue Lacy - the official state dog of Texas - the best dog there is!
