Hi everyone, my names Katrina. I juss got found a stray dog about two weeks before christmas. I juss recently found out she's a cockapoo. her names maryjane, i call her Jane for short. She is my first dog all on my own, and She is having some problems. I was reading up on cockapoos, and i seen that if not trained right they can be agressive and they can constantly be begging for pets, my Janiee does both of this! She wont let my mothers dog come in my room, or my brother even get close to me with out trying to bite them! not to mention she can never let me juss' sit, she always wants me to pet her! I juss want some advice.
