What is the "brindle factor?" If it means the brindles get into more trouble I really can't agree. My Riley (fawn) is way more into things than Max (brindle) ever was.
Actually at the time it was a comment made in a joking manner, as she had a brindle pup who was absolutely mischievous like my Spirit and 1 very calm fawn like my Xena. In my family it goes like this...(I prefer the term goofy as opposed to hyper)
myself - 1 calm fawn...1 goofy brindle
mom - 1 calm fawn...1 goofy brindle
brother - 1 calm fawn - 1 goofy brindle
sister - 1 calm fawn - 1 "manic-depressive" fawn...
The comment is just a joke. I know the coloring and markings have no direct result on the boxers personality or temperament.
