MOL! My puppy tricked Mommy!

I have a whole new respect for my dog Pen! Some people had organized a free/low cost spay & neuter day which took place yesterday. They sent a truck to the local church parking lot to pick up dogs and cats whose owners wanted to have them spayed or neutered. Then they would drive the pets to the clinic for the operation, and return them to Squaw Valley in the afternoon. Mommy wants to have Pen neutered, so she set her alarm really early yesterday morning so she could be down at the church parking lot by 7:00am. When she went to put Pen in the car, she saw he was foaming at the mouth! At first she thought maybe he just chewed some grass or something, so she wiped his mouth off and they headed down the hill. But then Pen started REALLY foaming at the mouth and drooling big gobs of drool all over himself and the carseat! Mommy freaked out and decided to take him to the vet instead; She didn't know if he had been poisoned or bitten by a snake, but she was crying and praying all the way down the hill, pleading with Pen not to die. When she got to the vet hospital, the doctor wasn't there yet because they don't open until 8:00, but the vet tech arrived shortly after Mommy and Pen got there and said they could sit in the waiting room. As soon as they sat down, Mommy saw that Pen had stopped drooling and frothing at the mouth; Instead, he was bouncing around and wagging his tail and acting like a silly puppy! So after 15 minutes, Mommy decided he was okay and there was no reason to pay a vet bill since he now seemed fine, so they left. Of course, by then it was too late for Pen to get in on the low cost neuter deal. I think he must be psychic...He TOTALLY faked Mommy out! Bwahaha...High five, Pen!!!
