My dog says he is disgusted that Jon and Kate (of Jon and Kate Plus 8 fame) are dumping their dogs because they're too much work. Dogs are a LIFETIME commitment, not some thing to be discarded if your life changes.
However, based on what Jon has said in the past about his kids being rough with the dogs, maybe Shoka and Nala will find a better home the second time around. Dogs can be a wonderful addition to a family with children, but the kids must be taught to interact with them in a kind and loving manner.
Good luck, Shoka and Nala. Here's hoping your new family is better.
P.S. Don't breed or buy while homeless animals die. Adopt your companion animals from the shelter!
