Breeayne, I'm so very sorry that you have had to make such a difficult decision. I had to make that decision a few months back with my sweet little Gigi and I truly understand all the doubts you are feeling. Did I do everything I could, should I get a second opinion, maybe there's just one more medicine out there...The list of questions and self doubts were endless.
But Breeayne, I trusted our family vet implicitly and I knew when he told me it was time, it was time. I couldn't live with myself knowing that her sweet little body was in pain and that there was nothing more that could be done. So, we do the unthinkable because we love them and only want what's best for them. For me, I knew I had to accept the pain of her physical absence so she wouldn't have to suffer the pain on this earth. You sound like a remarkable pet momma and your little beautiful collie mix will forever be with you. My sincerest sympathies.
My warmest regards, Carmen's and Gigi's mom - alicia
