Our rescue brought back 21 dogs in total over the past two days. All of them were well fed, dirty, matted, friendly but undisciplined, and outwardly in good health.
They appear to be pure GSDs except for one chihuahua (also saved by our rescue). They may have been mistaken for mixes due to their unkempt condition.
They will go to the vet for checkups and spay/neuter after their cleanup.
I saw from the pic some were long coats and some appeared to have the panda coloration which may be why they were assumed to be mixes? Do they know why the breeder just left the dogs?
