I am a little concerned about KD, my 62 lb 11 month old on our tile floors. She has thin legs and seems to walk stiff legged on her tippy toes. As she walks on the tile each step slides forward a few inches. It's kind of cute the way she walks but I worry it may effect her later in life. When we go for a walk she walks stiff legged and sometimes limps (not sure why). The other big girl has no problem unless she becomes possessed with the zoomies. The smaller KD has been compared by my son to a lamb and I compare the larger Karma to a lion in the way they carry themselves. Don't you just love golden retrievers? Does anyone have this same problem and if so, aside from covering your floor with area rugs - can anything be done? Dumb question - I guess what I'm asking is does anyone think it will cause long term damage?
