I have a german shepherd and she won't eat and is limping but, will drink and all she wants to do is lay around. We just brought her in the house a week ago, she has been outside for a year now. What could be wrong with her PLEASE HELP?? She keeps licking her vaginal area and panting. What could be wrong? And is there a home remedy?? We don't have the money to go to a vet :0(
