I have a 14 year old Boston Terrier. Suddenly tonight, she started screaming in a manner that I cannot even explain. She is blind, so she was walking/running around the house very quickly and running into walls, doors, knocking things over, etc., while continually screaming. After about 5 minutes of this, I rushed her to the vet because it was not going away. In the car, she kept screaming and trying to jump out of my arms. The vet shot her up with some Valium, and she calmed down. I was able to take her home, and she seems to be close to normal, though she is still pacing. No screaming though. Here is some more info: - For the past year or so, she wanders around the house aimlessly, and barks at closed doors until I open them. This usually starts around 4PM, and can either last a half hour or all the way until 8PM or so. I just figured this was due to blindness, or senility, but realize a brain tumor/another brain issue is in the cards. - She had 18 teeth pulled 8 days ago. She
