I am a new puppy owner & going through the series of shots needed. My pekingese has gotten 1 distemper shot & her rabies shot (on separate days); however, after her distemper she was crazy. It appeared as if she forgot her name & she barly walked around. She was rolling everywhere and flipping around like a mad-puppy. Is this normal... should I be concerned... her 2nd shot is coming up & I'm not sure what to do?!
