Ugh that is so sad.... It just breaks my heart.

Something very similar just happened to my cousin's Papillon, Cosmo. My cousin is in a wheelchair because she was born with this muscular disease, and she went out to take the dogs for a walk, and two of their neighbor's dogs ran over and attacked Cosmo and he didn't even make it to the pet hospital... All my cousin could do was yell, watch her little dog get beaten up, and hope that the dogs finally stop attacking it and that Cosmo lives...
