Vinny.....I remember when you went through the same heartbreak with your sweet Toby - just about 9 years ago. I'm so sorry this is happening again and so damn soon!
You already know this but I will say it anyway - your focus right now and through his final breath should be 100% Syd's comfort.
I posted here in March when I had to take Billabong to the overnight emergency vet to be put asleep due to lymphoma. She was never in pain - and to this day as hard as it was to make that excruciating decision - I felt I did the right thing - and that brings me peace....as it will you.
You know how to reach me if I can be of any help. Much love to you and your buddy......Baz and Winkipop
