I just adopted this rescue dog. He's a sweet and timid little dachshund missing one leg. He's precious.
That is so sweet.  How did he lose his leg?
He was found with a wire in it because he got caught in it.  It was too infected to save.  It doesn't seem to bother him not having it.
I've heard that it doesn't bother them to lose one limb.  I watch Dr. Jeff on Animal Planet a lot and that is what he says.
