Second Chance For a Sweet Puppy

Hi everyone. Two days ago I had a boxer mix puppy that came into my work and she needed surgery asap to fix her hip. She would have to undergo a Femoral Head Osteoectomy and a Spay all together along with her first set of vaccinations. The previous owner had her for only one day and stated that the puppy fell from the top of a playground slide..long story short I had bonded with this pup and thought she was going to have surgery only to find out that the owner was going to euthanize this sweet baby because she could not afford the surgery bill. Of course I couldn't let that happen.. I was a wreck when I found out and asked the owner to sign her over to me and thankfully she did. I know I can't save all the animals but with this puppy it was different because she reminds me so much of my 1st fur baby. After Josie was signed over to me she immediately went into surgery which came out to almost 900$. I really didn't have the money to do this and it came up out of the blue. Please anything will help. Josie is recovering well but she has about 6 weeks of recovery to go and will have to undergo physical therapy.
