Dental surgery for Daizy

Daizy is a thirteen year old toy poodle. She was a birthday gift to me when I was nine years old, and she's probably the most important thing in my life. She's a senior doggy now, and dental issues are common with toy poodles, but we never brushed her teeth because we didn't know we had to. The vet told us that  her teeth are so rotten that some of them are only hanging on by the tartar. Over half of her teeth need to be removed and if they are not then it could lead to heart or kidney issues. Daizy may be an old dog, but she still acts like she's a puppy and she's so full of life. It would mean so much to me if she were to get this surgery. Her teeth wouldn't hurt her anymore, she could eat again, and it would lengthen her life and improve the overall quality.
