Wikiwandering, I came on a piece about Pete the Pup who was originally a Staffordshire Bull terrier. The ring around his eye was almost perfect, and was completed by hollywood makeup artist Max Factor. Yes, that Max Factor. Later Pete was replaced by a pit bull- you’ll notice the dogs circled eye moves from left to right in episodes- and was eventually snagged by Target to be their mascot.

Weird, some of these connections.
