So...my older daughter (15) and my hubby are super excited about wrestling with the girls when they get older (only 8 weeks now). However we have another daughter and son who I know want no part in wrestling/being tackled by the dogs. And another son who is indifferent. Can we teach them that only some people like to roll around? Or will this become a free for all and should be avoided ie not ok behavior at any time. Thoughts?
