Congratulations on your puppy! Good job getting him out of that situation, 5 weeks is too young to leave the mother but I am glad you got him away from that bad breeder.
If I were you I would report that breeder…sounds like the animals she still has are in an abusive situation.
What a sweet face! Thank you for taking her in, she needs a forever home.
As Pat indicated, unless you have info on the parents being clear, or at least one clear, she should be tested for Fanconi asap.
Her name is Mattie and she is a real sweetie. My son brought her home from a mission trip in Appalachia. She has become my shadow and we just can't imagine not having her around.
