My min. schnauzer (3 1/2 years old) has been anxious since birth. She will not come to anyone, sits in the house and keeps an eye on the doors most of the time. Someone comes to the door she goes crazy. Took her to obidence school, she can do the sit and stay no problem (she is very smart) It took a long time to get her to come out from under the chair at school and except the other dogs and trainer but she never really warmed up to anyone. My brother comes over once a week and finilly gets her to take food from him but the next time he comes it is like she never know him. There is more but I think you get the idea. I finilly talked my vet into trying Amitriptyline with her. It has only been a week but she almost seems to be a bit worse. When she hears the cell phone beep cause the battery is low she sits in the corner and shakes, she used to only do that now and then with another noise. I was wondering about trying L-Tryptophan. Any suggestions would be welcomed. Thanks
