So the story is, we got Lola a year ago from a chihuahua breeder here in the area. She took to us very well from day one, she also was already trying to dominate or mount my foot from the beginning. For me it has been a constant battle between her and I, she was getting possessive over toys for a while and I just simply removed the toys from her and gave her something of less value. If shes chewing something I dont like she will drop it now and before she would growl and give me attitude. She knows how to sit, stay, lay down, and go to your bed, I try to make her sit or laydown before giving her food or throwing the ball or going outside. The problem is that ever since I started to take her to the Vet for her first shots she is terrified of people, we can go on walks and she is fine until someone trys to reach down at her. If I am holding her and someone gets too close she gets very defensive and sort of rolls her head upside down and opens her jaw. To top it off she has had more bad experiences with dogs than good, the other day a 2 month old puppy whos owner didnt have it on a leash ran up to her to play and she wanted to bolt, again opened her jaw as if she didnt know what to do. I have an appointment with a trainer next weekend to help me with these problems but maybe some of you have experienced similar issues.
