Boxer puppy need new home

Our female boxer puppy will need a new home. She's almost eight weeks old, had her first shots as well as first round dewormed. I've got vet papers to confirm. She did very well in the crate, and through the night too, very playful and caring. She's a very nice puppy but not the best match for us. Rehoming her for $300 but for the right case, we'll take less.
