The dogs - Maise is an Australian shepherd and Keller is a Great Dane - have a condition called double merle. A genetic abnormality, double merle dogs have two copies of the same gene. It's often the result of being overbred.
It's no surprise then that both of these dogs came from breeders - an industry focused on producing as many puppies as possible for sale.
Maise was just 4 weeks old when the North Carolina family who bought her realized she was deaf and blind - a fact the breeder failed to mention.
"The family quickly realized something was wrong so they put her on a Facebook yard sale site as free to a good home," Woodward explains.
The thing is, when Woodward saw the ad she wasn't so sure Maise would find that "good home."
Besides, unlike Maise's first family, Woodward knew all about deaf and blind dogs. After all, she had one of her own in Keller.
