the pitbull is 11 weeks. Presumably this behavior will escalate as the Rott matures and grows in strength and confidence unless serious intervention from a trainer happens right away. I hope that the Pit bull is being reared correctly. If not I can only imagine the situation of the two of them together once they are both mature.
