With the last litter Milo, the sire/dog, on occasions was a little rough when playing with them but not meaning to be. He is very good with his front paws - could teach him to tie a knot if I had the patience and loves to shake hands and also likes to give things a bit of a tap at times - like the cat when it is asleep - and he can tap a little harder than he means to at times. He's a year older now so I'm hoping he'll be a little more sensitive this time with the pups. Still, I will need to keep an eye on him.
