Poor guy... I have all I can handle or I would love to take him. I prefer adopting older dogs, they're past the puppy crazies, housebroken and usually are willing to go for a walk or just chill out in the house.
I just hope there's a special place for people who would dump an older dog. We found an elderly brittany wandering down our road years ago. We didn't think she could have walked too far so we picked her up and drove around, stopping at houses to see if someone had lost her. No one had, no lost signs were put up, no one responded to our found signs. Vet said she had to be around 16 - we kept her and she died a few months later. Poor girl...
