I've written before about how a mountain lion looking at a house cat only sees lunch. But a large dog looking at a tiny dog only sees a pal.
We were in The City a week ago, walking along Post near Union Square, when we saw two puppies playing inside a hair salon.
Turns out they were both 4 months old. One was a Great Dane, maybe 65 pounds already. The other was a Chorgi, a Chihuahua-Corgi mix, maybe 2 pounds.
The Chorgi was up on a table, and the Dane stuck his head over the table's edge. The Chorgi jumped around on the Dane's head, nipped at the Dane's nose and ears, and acted as if he'd just discovered the best new ride at Disneyland. The Dane endured the assault, wagging the entire time.
It was a classic example of how dogs recognize their brothers, and it was great entertainment to watch.
