Without a doubt, the toughest thing I've ever had to do.

Was up all night with my buddy Nacoma. His health and age(16) finally was too much for him and me to handle. His arthritis in his hips has been getting progressively worse the past couple of months. Last night was a nightmare. He was just in too much pain. Kept falling over. Called the emergency vet this morning, me and my wife took him in.
After talking it over we decided it would be the best thing for him. After crying hysterically for 10 mins I gave the vet the ok. Me and my wife spent some time alone with him. Then I laid on the blanket with him while the vet did what he had to.
The worst part was walking in the house and not seeing him there and his empty dog bed. Thats when it really hit me. Been cryin uncontrollably all day.
Rest in peace buddy, I will miss you greatly
