My dog died recently, what's the best way to move on?

My childhood dog, one I grew up with, trained, and made a part of my life died last week. He lived at my father’s house and I believe my father’s fed him some food that got him sick. I still cry almost every day, and I’m afraid of losing my other dog (who is only 1½). I just can’t seem to move on, what are some ways that have helped you move past the death of a beloved pet?
