Well, stepped out the house this morning, and the dog was laying in the garage in his normal spot. All seemed well, except he didn't get up. When he did try, he couldn't. Fooled with him, and he didn't seem sore to the touch. Seemed out in has back end. I couldn't tell if it was his spine, hips, or hocks. Took him to the vet. They kept him all day. $294.70 later, they said it was growing pains. Didn't know dogs got that. Anyway, he's 99% now. Part of me suspicions, that it was for attention. Idk. Ever heard of that?
