This happens every so often and we could never figure out what causes Mr. B to go crazy and have a rampage around the house, actually his rampage is really only in this area. We were able to deduce that in some instances he was trying to get a toy out of the toy bin, but his arms are so short that he pushes the toy bin around until it topples over. However, this time, the rug was all pulled up and the sofa was pushed back. After putting everything back and letting the pooches out, we see Ms. M crawling under the sofa for something. She comes out with a kong filled with treats. Apparently Mr. B knocked his treat filled kong under the sofa and he was desperately trying to get at it. Unlike Ms. M, Mr. B has really stubby arms so he couldn't reach under the sofa and fish it out with his tiny paws. Poor Mr. B, after all that work, Ms. M got the treats.What we can't figure out is why Ms. M's crate was moved around.
