People be against bark collars and or some sort of bark deterent but be letting there dogs bark all loud all the time in the neighborhood.  This is wild to me.  There are great ones on Amazon.  Bigger breed, smaller breed, you should DEFINITELY get one for them as a pup.  It doesn't hurt, it teaches, lowers anxiety, and more

Stop thinking you might breed them....or whatever.  Do it!  Don't wait unitl they are a year old.  Between 8-10 months at the latest!  I don't care what your vet says.

I know you like that breed but maybe that is too much dog for your apartment.  I know you will try to train them but still...it's like getting a bigger house than you can afford, your rent is half your monthly salary.
