From what we understand Joel was from a breeder who was using her to breed puppies when received her her back legs were not functioning now she’s able to walk jump run she’s still a little wonky when she walks but she is high energy and playful extremely quiet we have not heard her bark one time in the three weeks we’ve had her or wine she’s potty trained very well behaved very good around people and other dogs or animals we don’t know her background we just know that she’s a sweetest dog we’ve ever rescued
