Look at Sandy.  She is smiling that she gave birth to NINE pups.  All black.  Dad is unknown.  Sandy is approx 3 yo, and a lab mix.  She walks with a limp.  Her leg must have been broken at one time and was not set right.  Our vet does not think she is in pain, and it does not affect her getting around.
If you are interested in adopting her, please do an application, which can be found on our website www.careofdc.org
