thats all very scary. I havent had any close encounters like you both have, but i worry because Molly is so friendly to everyone. I always make sure i have some treats in my pocket, and as she is such a little piggy, i like to think i can call her back to me quickly if i need to. When she is off the lead running about, I feel as though i need to constantly check the whole area to see who is approaching. I put her back on the lead if i feel unsure about anything. Oh how i wish we lived in a safe and happy world!
