I have a lab mix with something unknown (was sold to us with fake purebred papers) and she is the absolute perfect dog.. Aside from the copious amounts of hair that she magically sheds daily. I'm talking if we didn't sweep/dry mop our floor 4 times a day we'd have tumble weeds of her hair if we had breeze.

She never barks at family or on her own (honestly we thought she couldn't for the first week we had her), only if strangers are at the front door/come over. Only ever shat once inside, after negative enforcement she's never done it inside again. Always "asks" (looks up and waits for someone to say something) before she eats food, even her regular meals.

She's the only dog that I 100% trust never to bite me in any situation. Can't say that about the previous dogs that were apart of my life.

TLDR: The hair and effort is worth it. It's not even a question for the perfect dog.
