Oh I'm sorry...just remember that small dogs will get adopted before those "large black dogs"
You are probably right, it's those cute cute Christmas puppies that are being sent to the shelter....Little dogs can be more of a handful sometimes than the bigger ones and many people don't realize that.
I will never understand why anyone feels that dropping off a dog at a shelter/SPCA/Humane Society is an acceptable solution....
Hang in there. Little dogs stand a better chance than bigger ones in the world of adoption statistically(did I spell that right?) Just be prepared to see some of them again You're a saint for volunteering and caring.
