Pat, mom, and I took Harley to the vet today. Like we thought, he was diagnosed with diabetes. We made a very tough decision after a few hours and decided it was best if we put him to sleep. It was the worst feeling in the world. I didn't want to leave him and it hurt so bad. I miss him so much. He was a really good and loyal dog and he will never be replaced. I hope he's in doggy heaven surrounded by raw-hides, looking down on us. Harley, you will never be missed and one day we will meet again.
