Dog Park Day 7

Merida absolutely loves going to the dog park buuuuut only if she's inside by herself. Usually nobody is there when I go over and she chases her ball and frisbee but once a dog comes in then she never leaves my side. She will eventually sniff some butts and then sits on my foot. I tried to leave her on her own in the cage but she stays next to the fence and watches me like a hawk. Luckily everybody has been super sweet and understanding of her behavior. She is very shy and I'm hoping she will grow out of it after a number of visits. If you know of any tips and tricks please share. I would love to hear about your pup and share some insights =D
