Great Dane and Papillion owner

I've got a harlequin Great Dane that was a rescue at 5 months old named Shiva. The breeder wanted to put her down because he only sold show dogs, and she was an overmarked Harley with one blue eye and one brown eye, and I think she's the most beautiful dog I've ever seen. She's now 2.5 years old. Ive also got a papillion named Indra, who is turning 2 July 16th. She's always grown up around big dogs, so she has kind of a big dog mentality. She's very smart, when her sister and two lab retreiver cousins played tug of war with a chew toy, she'd wait for them to fight about it, run below them, grab the chew toy, and run under a car!
