Hi everyone. I'm sorry I didn't respond sooner. I've just been very busy. I did take my Yorkie to the Vet but they were unable to find what was wrong with him, they did however rule out liver shunt. He is still walking the same way but doesn't appear to be in any pain as of now. He has also gained his personality back and is acting as he normally would. The vet told us that he may possibly have a displaced hip because he is only 3 pounds and likes to jump alot. We have another appointment for him next week at an animal clinic in Orange County that deals with both orthopedic and a neurological problems. I will keep everyone updated as soon as I learn more. Thank you all for you responses.
