I think it is personal preference really.I have five dogs, 2 males and three females. The females all want to be alpha so you have to be somewhat careful of that. My male yorkie was the easiest of all of my dogs to housetrain and has been trained completely since he turned one. He is the most mellow but he still oves to play. He is not a bully and does not get jealous. My girls had jealousy issues for a while but have resolved them now. It took about 4 months to work it out.
Good luck and congratulations! |
