Fran, she rarely gets that wild now, but she came to us used to having dozens of play partners to just Arwen, who wouldn't play with her yet, and us. Now that Arwen works her energy off, she is much calmer. But when she does play, her mouth is very soft.
Leora doesn't let her play bite her at all now, but she still likes to hold her arm or hand in her mouth and rub with her tongueโฆ almost a nursing behavior. Since Leora is a bit germaphobic, it is an act of love on both sides.
My response was to the poster on Youtube though. I agree people should do what they are comfortable with. I happen to think learning superior bite inhibition comes from play biting and keeping that mouth loose no matter how excited. And I think it is important lesson that simply "no bite" doesn't always cover.
Although... omg been so long I almost forgot! When we got Sayblee, I would squeal OWWIE and she bit more. I called the breeder laughing and said I just recognized a big difference between my Rotties, and in fact MOST dogs I had worked with, and Basenji. Squeak with other dogs, they get "that hurt, don't do it." Squeak with a Basenji and they think "Cool, do it again!" LOL.
