Deb,
What a sad story and they can't even keep one of them, preferably the female? - as it sounds like she is easier going around the toddler; oh that's right, no dogs in the M-I-L suite
Our Humane society here in town says "moving and can't take the dog, and Allergies" are the top excuses for relinquishing pets. Too bad she didn't think twice about aquiring the second dog when she was planning a family in the near future.
Very sad for the dogs
and hopefully they will be found an appropriate home.
