Angus, our mastador, adopted from the humane society at 4 months now 10.5 months old, is driving me crazy! He’s extremely loving yet incredibly destructive. Never went through this with our other dog (4 yrs.). Angus destoys an average of 3 things before noon each and every day. And yes, I try to watch him but I do have to attend to basic chores and shower ya know?! We’ve supplied him with plenty of kongs, hard rubber chew toys, tons of stuffed animals – which he is rapidly de-stuffing, a special cuddle/comfort blanket to drag around. We live on a beautiful 1/2 acre of land with a creek along the back property line, and a view of a river and a mountain. When we built our split rail 4′fence it was able to contain our other 2 dogs, but Angus continues to either jump over it on through it.
