I think Murphy is happy to be home. He missed his sister and they are now inseparable yet again. (Note: when they are not happily napping together they are usually beating each other up.) Also, while he was gone, Murphy had to stay in a kennel for several months. I think he is happy to get his soft spot on the bed back. He keeps wanting to snuggle on our bed instead of stay in his dog bed. At this rate, we may need to upgrade our queen to a king! :)
He's pretty much been his normal self - destroying the backyard, wanting to retrieve anything, and eating up a storm. When he was gone we hardly spent any money on dog food. Now the expense is back as he will eat 8 or more cups of high performance dog food daily.
