I have an 11 1/2 yr old German Shepherd that is not wanting to eat, when I let him out to go potty this morning, he seemed like both of his back hips (or legs) hurt, he then went into the dog pen, walking gingerly, and layed down and drank from the water bowl, then refused to get up and go potty or even go back into the house. He has been getting skinnier over the past few months but eating fine until just about 2-3 days ago. My daughter and I were able to get him to come back into the house, but he seemed so weak to walk up the stairs of the deck, then didn't seem too excited about coming back into the house, and it's raining, which he doesn't like rain. He has been on a diet of Blue Buffalo Life Protection Formula for several months and doing fine. He is just laying on the floor, not wanting to get up. I have another dog who is just fine. What should I do, what could be wrong??? I do not want to spend hundreds or thousands of dollars for a vet if it is inevitable that he is dieing... I love this dog... but just cannot afford this right now... don't want to seem heartless.
Thanks
