We remember celebrities because we see them on TV and in movies so frequently.  Here are some celebrities who resemble equally famous dogs.

Barbra Streisand / Barsoi. With her long nose and sharp features she can easily be taken as a cousin of the Barsoi.

Brad Pitt / Schnauzer
Brad Pitt with his trade mark beard and looks can well belong to the Schnauzer family.

Larry King / French Bulldog
We often see this French Bulldog on the TV.

Janet Jackson / Toy Poodle
Janet Jackson borrowed her hair-do from this poodle.

Dom DeLuise / English Bulldog
We see this English Bulldog so often.

And this great celebrity.  No prizes for guessing how he looks like.
