Puppies are adaptable, for getting to know kids and cats.
Boxers have an odd sense of humour that can keep you guessing, but entertained!
Also voracious eaters, main thing to watch.
I have had a border collie, and a lab mix.
Agree with the above. Border was outrageously intelligent, labmix sweet and devoted.
Differences were in eating - the border only ate what he needef and wasn't at all food anxious.
The lab walked away from aggressive animals where the collie didn't mind...
