Sad news, this really caught us by surprise.
Our younger dog, Linus, has an inoperable tumor on his spine, and will have to be euthanized tomorrow.
He is 10, is a rescue, and we have had him since he was 2. He is 65 lbs of solid muscle, and fast as the wind. He is very friendly and listens well. He loves to play fetch and tug, and has a fierce "allegator shake", but the only thing I ever saw him hurt was the raccoon that tried to rip through the screen and get into our house (Linus did not have a scratch on him, but the raccoon did not survive).
He also loves to go for walks, hikes, and ride shotgun. Kids and adults alike love to pet him.
We had him DNA tested. He is equal parts of Pit and Boxer, with a little Australian Shepard, Grate Dane and Nova Scota Duck Tolling Retriever.
My wife and I are devastated, and my eyes are not dry as I write this.
