Keep busy with all the cool stuff you are doing out in the country. I know its not the same, but I had to give my German Shepherd the needle a couple years ago and I was miserable for several months. Shepherds are very smart and very loyal. My dog went everywhere with me in the back of my truck. She was so big that once she was gone there was a very noticable void in our home.
Hang in there. Every living thing I have ever loved and lost always made me feel like I would never be the same again...but without exception the passing of time eventually eased the pain of my loss. I can even look at pictures of my dog again without crying like school girl. lol.
