What about pit lab mixes? A niece now has one and he is 60 # and a lap dog. Long nose half up ears and he points at rabbits. He worries me because he rarely barks.
We have a similar situation; my wife found a 10-week-old pit/lab mix, lost and injured on the side of the road, and brought it home. I was really wary about it, but he’s turned out to be a good dog. He now weighs 88 pounds, but we have a Chihuahua, a sheltie, and a miniature dachshund, and he’s never bothered any of them.
I have trouble with him while recovering from a hip replacement - and being 72 years old - but, he minds pretty well unless the sheltie is in heat.
If he gets to rowdy, the Chihuahua (the alpha dog) puts him in his place, and he tucks-tail and cows down.
He has floppy ears, one golden-brown eye, and one moon eye...and the loves water.
