My friend got two cocker spaniel puppys recently, two sisters, so cute! I brought lady for a visit last night and they were rather a bit too much for her. She insisted that she sit on my lap the entire time while the puppys tried to jump up and bite her tail

Anyway when she was down she started drooling profusely, it was all on her ears and running onto the floor. This never happened to her before. Does anyone know why this happened. Thought it was rather odd.
