Thanks for the positive words everyone! She is still doing great, but now I am worried her incision site is infected! The site swollen...I just sent a picture over to my vet. She is on antibiotics, so wouldn't that stop an infection? What happens if it is infected?

Here is a picture:

Update: It has been two weeks since Beesly's surgery and she is doing great! She can easily get up and down on her own, she is eating normally. She does seem to get tired but I think figuring out life on three legs can be exhausting. She definitely has her personality back; she stands by the front door wanting to go on walk, she sits in the kitchen while we cook, and barks at any delivery being put at our door. She gets so excited to see any family that visits. We keep her down and calm, but it is hard to hold her back when you were dying to see her personality come back. The stitches come out tomorrow so we are excited to really get more walks in!

The vet said her biopsy came back inconclusive, but they think it is osteosarcoma. There were no signs of the cancer spreading so the vet said she may live a few more years! So we are just going to enjoy having her here, however long that may be. We are just happy she is pain free and able to get around so easily.
