thanks Ellen. we have a ywo yr old mini schnauzer that suffered an spinal injury (we/vets are assuming) while playing yesterday and can't move her back legs at all, nor can she pee on her own. Tomorrow she gets an MRI and hopefully we'll know for sure what hapoened and if she can be treated. Your video is a great comparison and gives us a reminder how a human design may (or not) be attractive to a dog. hopefully we won't have to buy one at all.
