Kalki, our 8 month old puppy is actually such a baby - he hasn't yet developed hard paddings on his feet, and has tender 'baby skin'. During our vacation, we were playing in a parking lot and the skin n all his feet got torn off, and he had to be taken to the emergency vet. And no, he didnt stop playing when he got hurt. And he seems to get hurt randomly so many times when he is simply playing outside. Anyways, I didn't want to see his feet bleed again, especially when it is so hard to keep him confined. I got him some nice doggy boots and his face tells how much he doesn't like them!
