Dog Peeing in Kennel Since Death of Other Dog?

Our older dog passed away last Sunday and now our younger dog is peeing and pooping in his kennel when we leave him. We have only left him for a few hours each time and we put him outside prior. He still pees in the kennel. He is a nervous dog that we rescued at the same time as rescuing my older dog so they have been together for five years. He is eating and drinking, but not as he did prior. He is quieter than usual. We know he is mourning, but want to stem the peeing in kennel thing as he was difficult to crate train in the first place. Any ideas?
