My mini schnauzer had a lot of energy when he was younger! He also used to get bored a lot if we didnt play a lot and get a lot of exercise. He would chew up rugs, the wood on the corners of walls, the kids clothes, socks, kleenexes! For a while it was like having a third kid - only he was the naughty one!!! Lol!!
As he got older it got a lot better and he could actually be left at home without worry that he would wreck the place!
Now that he is an "old man" he mostly sleeps. We noticed that he is starting to lose his hearing - doesn't hear the doorbell anymore. He was diagnosed with diabetes a year ago and he really seemed to age after that. He gets insulin 2 x a day and I think it makes him tired.
