TPLO For Dag (Rescued Pitbull)

Some of these pictures are hard to look at but I wanted you to see the progress. This is my princess and her name is Dag. I use to live in Flint and I found her locked in a cage and obviously wasn't fed or given water for quite some time. She was covered in fleas and her own bodily fluids. I took her in about 4 years ago and she means the world to me (even though I wasn't really financially ready for a dog). She spent the first 2 days crawling because she didn't have the strength to walk yet. After weeks of feeding her half cups of food (if i fed her anymore she would puke it right back up) she started looking better. Her head was covered in blood and fresh cuts (my guess is she was a bait dog for dog fights). I then got all her shots and even though I got her to a healthy weight she was stunted due to being malnourished so she's fully grown but small. She's always kind of had a limp on her front right leg making it hard for her to jump off of the bed/car/couch things like that. She now has a torn ACL and the surgery is going to cost about 1500 plus all the extra care afterwards. I truly wish I could just pay myself but I need the help and I can't fathom having to put her down because of this. Every penny will help and i will post pictures and videos of the progress I've never had to use gofund me and I wish I didn't have to but I'm out of options and this is my baby I would do anything for her. I know there are a lot of other things that are more important to donate to but I'm asking for help because it kills me to see her in this pain. Thank you to anybody that helps in anyway. I don't know how to add additional photos but if you want to see how much she was progressed I will gladly send them to you.
