I'm working on this actually. I had a dog for 12 years and she really kept me going. Saved me. But she died a couple years ago, literally the day after one of my parents, and it's been tough. But I'm really thinking about getting another dog; I really want to get another dog.
Get another dog. I would if I had a little garden for them. It sounds like you already know you should/want to.
Go get it man, they are the best.
