Yo Sammy - as much as I really hate saying this - he may be getting near the end of his run.

No way am I telling you what to do. I'm no expert on canine health - your vet would be that person as well as a few on here (Siberian for one).

Huge respect to you for giving your all to your companion, as he has done for you all of his life.

Please give your buddy a belly rub and head scritch from my 2 girls.

Praying for you both.....
