Our Dog is Limping

We rushed our dog, Buddy to the vet hospital two weeks ago. It was the day before we went out of town when we noticed he's limping. We have no idea how he hurt his leg but it seems to be causing him a lot of discomfort. We supposed to take him with us, but due to his condition he needed to be on leash for at least two weeks. 

 He's still limping his rear left leg at the moment. I hope he gets better or else he'll be wearing one of those dog leg braces. Surgery will cost us $1700, and we don't have money for that.

We went back to the hospital yesterday for follow ups, and the doctor gave us a few prescription meds. I'm glad he's not weak and still has appetite to eat.
