Well today I took my pup to the vet for his last set of shots. I feel like such a failure. He TOTALLY FLIPPED OUT!!! Barking, screaming, biting... I have never in my experience seen this type of behavior from an animal. I couldnt believe it. I sat and talked with the vet for about half an hour. He has shown signs of aggression before but never like this. I cried all day and decided that I could not trust him with my 5 year old son. He is only going to get bigger. I had to take him to the local shelter and explain. I just feel like Shi*. Thanks for listening.
