Izzy had her fourth and final Parvo booster this week. She weighed in at 11.5 lbs. One final round of shots in two weeks and she will be good to go. Anxious to get her socialized with other dogs. She is terrified of big dogs. Had her for a walk in the neighborhood yesterday. She was approached by a large dog on a leash. She shreiked and peed herself. Incredibly sad to see her so terrified.
