Puppy bak please help! :(

our puppy Blaze is at the mt shasta animal hospital and they won't give him back to us without paying $380.00 we paid them $250.00 deposit for the stay for parvo but he is doing better and they did'nt tell us we had to pay the rest of the payment to get him back as we were making payments on this account allready for his broken leg which happened when a mean lady kicked him for going in her yard, they are charging us $40.00 for each night he is in there and we are on very limited income we work very hard but barely scrape by to survive, any donations would be much appreciated little Blaze has been through so much this last month and we just want our puppy back anyone who can help God Bless!
