What a lovely girl. I teared up when I read about her osteosarcoma. I lost my much loved old gal almost a year ago to that dreaded disease. She too was a byb dog but she made it almost to 10. We opted not to do the amputation because of her age. I loved that girl so much but have never regretted letting her go when we did. It was her time and the last gift we could give her for all of the joy she brought us.
I'm so sorry for your loss. They leave a big hole when they go but when the time is right you will honour her with another lovey.
I'm sorry for your loss. It's an awful, unforgiving cancer.
We had a lovely 120 days and, then, a few quiet ones and a very sleepy,weak day that let me know it was time. She really never told when enough was enough (eating, playing, muzzle-punching to the end) but, as you say, it was my last gift to set her free from that body.
