Tinkerbelle died of mammary gland cancer. She gave up her strong fight on July 18th, 2008, 10 days short of her 12th birthday. My tinker was blind for 3 years due to glaucoma/cataracts, but was just as happy and playful. Tinker is now whole again in heaven, and is happy again. To all dog owners, please check your pets for lumps and any growth and request removal at once from a competent vet. From my experience, it is even possible that vaccination not be done too often after 8 years of age as this could contribute to cancer as some vets may suggest.
I still miss her terribly. Thank you tinker for the 12 years of joy and happiness that you have given me. You have taught me many things about life and death, and you were and are my guardian angel. Tinkerbelle, RIP and god bless.
