It's a shock for anyone young or old to lose a loved pet, but in time it will get better for you and maybe you can get another one to love and care for. Everything dies, that's just part of the circle of life. You should apologize to your brother for saying you hate him, because you really didn't mean it.He will miss your pet too. He probably dug the grave open out of curosity, not anything mean in that. I had a dog and had it put to sleep because he couldn't come up and down stairs without hurting.I have another dog now and I love him dearly. We have a feeling in our heart to love more than once, so don't put off getting another one.He was probably sick and God needed him in heaven,you will be with him again one day. Be happy he died peaceful.Love and peace to you.
