Hello, I have a one year old male fawn chihuahua named "Beans". Beans is a great dog, he loves all kinds of people and everyone who meets him just falls in love with him. He is very sweet with adults and children. He was very well socialized as a puppy so people are not a problem. The problem is that he has bad aggression problem with one of my other dogs. We have three dogs all of which are a year old, one scottish terrior, golden lab, and the chihuahua. Beans the chihuahua has a huge problem with the golden lab, she is a one year old female, who is very sweet and loving. At first we just thought that it was jealousy between the dogs but now it's just getting out of control. Beans the chihuahua is so aggressive that the lab is afraid to enter the house most of the time and other times they are just like best friends. So is there anything that someone could offer in helpping me with this problem, I would really appreicate it. Thanks in advance~ Ralph
