my boy Dobby he is a very calm Jack russel doesnt chew anything but his own toys we got him from a rescue he was hit by a car and the owners didnt want to pay the vet bill
the one thing he does is for about 1 hours time everyday he goes nuts wont let me do anything but play with him LOL
I have taken some video of him during that time here are some samples..
WATCH DOBBY PLAY SOCCER We found he will do this for hours and has good enough control of the ball to move it anywhere he wants it to go
WATCH DOBBY AND HIS BALL He is really fun to play with the about as tall as a street curb LOL wieghts in at 15 ponds and even though he looks like he is pissed he is just playing and will not bite even if you stick your hands in his mouth he just doesnt clamp down on anything that isnt a ball or bone LOL
