Hi Abby!
I just want to tell you that if Kobi is still wobbly walking, there is probably a disc that is pushing on his spinal cord. The more he moves, the more the disc will push. If you let him keep pushing it, it will most likely rupture and cause him a lot of pain and probably paralysis. You CAN prevent that if you put him on crate rest. He will not like it, but it is worth it in the end if it will help. Layla is now on 8 weeks of crate rest, and another yorkie from this forum is also on 8 weeks with the same problem. A site with a ton of good advice and knowledge of this disease is
Dodgerslist Home Page. They have a mailing list as well that I am a part of and the other member here is also a part of now, and there are hundreds of people there who have gone through the same thing with their dogs and are willing to answer any questions about the disease, pain, drugs, therapy, etc! I would really urge you to join there because they can give you so much more support and advice specific to this disease than I can!
