Though I only had my golden pup for only two weeks, she hasn't had a hard time adjusting at all. Me and my girlfriend gives her so much love. The problem is, that I bought a Maltese last night. My golden pup plays rough with him, making the maltese cry. Sometimes when I'm playing with the maltese my golden pup growls at the maltese. Is this jelousy? It seems like it to me. How do I stop it?
