Definitely — a break is often a good idea if
puppies are getting themselves too wound up, or if one
puppy is bigger and
stronger than the
other, or if one
puppy is finding the game too much.
I did a lot of reading and attended some classes when my son brought home his Pit Bull, this is where I learned about the their attitudes and tendencies... about their fear factor, they are tenacious and
strong but they are actually less aggresive
than some of the more common breeds that nobody seems to fear, Rotties have a very powerful bite and a record of people attacks, but no one is banning them... so I would suggest you get your
puppy, take him / her to classes and get him / her socilized early on, let him / her play with
other dogs so they know that there is nothing to be afraid of... you'll have a wonderful time and you will become so much more wise from the experience.
