MaryKay,I was reading all the posts and wondering if I should respond,so here goes.I have 3 doggies ;one is 5 doxie next one is 9 mos yorky and the youngest is 5mos scottie.We had never had 2 pups this close in age before until now. The puppies enjoy the wrestling and this seems to be the way they like to play by rolling around with each other.They do not do it as much as they used to but I think with age they seem to have calmed down a little.I personally am glad they like to play with each other so much because at this age it gives them a chance to grow up together and go through all the phases of their lives together.In the beginning it was a little hard with going out during the nite but we all got thru that phase also and we now have normal bedtime hours.Time and patience will pay off in big dividends with the joy your pups can bring you .Its priceless.Cathy and Yoshi
