..ok...gotta chime in
#1 if this dog is not spayed ~ she MUST be ASAP ~ so she doesn't wind up in the wrong hands and it may help her with the aggression.
#2 this BLOWS my mind that a breeder would not GLADLY take a dog back if it is a wrong fit. And honestly, I don't give a crap 'who' is responsible for paying shipping. If my dog went to a home that wasn't working out, my god, the money would be refunded and I would get my dog back ASAP ~ and shame on me for not going above and beyond to make sure it was the right home/situation for this particular dog (who has aggression issues)....
I am really in awe about all this back and forth....
Responsibility NEEDS to be taken ~ This isn't high school anymore
