He looks full grown but is only 5 1/2 months old..65 pounds. When I am outside with him I hook him up so he can't go running off with the other dog. Loves to explore. Loves that ball! Don lets him run free..he comes back to him better, I don't want to worry about it :-) Thinks he is still a baby..jumps up in our lap! Loves to just jump up on the bed..even though he gets scolded. My paddle is a fly swatter..he minds when I just pick it up..ouch that hurts! Left the kitchen and had the freshly made cornbread pushed back on back of counter..you guessed it. He was chowing down when I checked on him..left one piece. Luckily we had just got ours. Oooooo did he get a scolding and swat. Have to just keep him out of the kitchen! But, he loves us so much, and, we love him.
