Awww.
sorry about your Rott having to go.


but are you sure that an ACD mix is a good idea?
ACDS were bred to herd... when they see something moving fast. the job that they were bred to do,, kicks in.. and the dog will try to herd it,, by chaseing it and nipping at it. would you like this to be your daughter?

when i was around 10 or something years old,, i was running around with my little cusion.. and the dog woudlnt leave us alone(she was an ADC) she tripped us,, and nipped us. she didnt 'bite us' just nipped us.. but it was hard enough to leave a huge bruses on my leg. but the at the time when she nipped me.. it didnt really hurt,, but the bruse itself hurt quite a bit.

but since your thinking of a mix bred dog... the herding instints may be tamed somewhat..
whatever choise you make. the best of luck to both you and your kid.
