I think I can safely say that Cooper and Austin know their names and respond right away but Leo is pretty stubborn and runs when his name is called.  Today I separated him from the other two and we played for awhile; everytime I called his name he came to me but I also paired it with one of his favorite treats.  This evening they all behaved very naughty.  Boys will be boys I guess because they did quite a bit of rough housing.  I had to use Cesar Milan's "shhhhst" and a three finger (like a jaw bite) on their shoulder to get them to calm down.  I am going to post some pics of their naughty selves in a bit.  Maybe a video too.
 
 
Today we made the trip to the doggie treat bakery in Austin named Woof Gang Bakery. My trio of doxies loves the mini Good Dog Chicken Pot Pie snacks.  We have been able to train them using these snacks.  Today we picked up the peanut butter and jelly ones.  The best thing about the bakery is that they have fresh baked treats for your 4 legged companions.  We were so embarrassed on the first trip because one of the puppies had an accident; we were just beginning to socialize them.  The owner and clerk were very kind and cleaned it up. They told us not to worry because it was not the doggies' fault they were just nervous.
 
 
Cooper, Austin and Leo henceforth when referring to all three I'll name CAL are tuckered out much like they are most days.  In the morning I take them out to run in the backyard, about an acre.  They come in and play on the back patio.  Daddy made them a gate because we couldn't find a baby gate or pet gate wide enough; and he says he doesn't love them, hee hee!  Well they still are pups and reached their 6 month milestone.  Later this morning we are making a trip into Austin to get their favorite treats (I'll mention the name soon of the pet bakery we visit) and to go run some energy at lady bird lake.  Leo is a bit chunky from all the extra goodies...we're going to have to check on his eating because I think he's stealing Austin's food, my thin guy.  I'll try to post and respond to comments on a daily basis so send them my way...
