I really know how ya feel .My best friend was with me for 16 years his name was Hobo.He had the big C and when I was at the whcm in June my family had him put to sleep.he is out in my back yard next to my shop .I could not do it so i dug his grave built his box and put his fav toy in it .still brakes my heart.best friend I have ever had.he was a German Shepard and at one time he weighed 143 lbs.when they put him down he was down to 97lbs and could not walk on his back legs .I wanted to keep him but I knew it was best for him to be put down.Even if I could not do it.And no there will never be another like him.I know because I have two more of them but they can"t take his place.
