We lost three pets, two cats and a dog, within 18 months. Our "chiweenie" was the hardest - he was almost 14 - we left on a Hawaii trip, thinking he was all right. Got a call from our petsitter who told us he needed to be put to sleep. Fortunately, the petsitter had been around him most of his life and loved him as much as we. Still, it wasn't easy. Definitely, the downside of owning a pet!
