I just had a black lab pass.I had him since he was 6 weeks old.He was put to sleep at 12.I finally had to put him down due to cancer.It was a horrible expierence.I had him in my arms while he was being inserted intravenuously.He was licking me,and looking me in the eyes,as if to tell me he was going to be ok.Im tearing up now,just thinking about it.I guess im just a big puss!
