My Daschund Has Problems Walking With Rear Legs. While Walking Right Leg Collapses But Recovers. He Still Wiggles His Body And Tail Wags While Walking. And He Had An Engorged Penis. What Is Wrong With Him?

He probably has joint problems you should take him to the vet and as for the penis that could be caused by testosterone and you may need to get him fixed if it becomes a problem it is better on a dog to get fixed they are not as hyper and they don't hutch on everything. Hope this helps!
