We had a Hawk scare here as well! Last weekend my husband was playing with Lola in the middle of a baseball field right before his game. We(sitting on the side of the field) all noticed a huge Hawk circling around him and Lola, So we all staring screaming at him when he looked up, saw the hawk and finally got the message and picked up Lola and brought her back over to us! After that the Hawk stuck around for about a half an hour on the top of the fence or on the lights for the field! Gave all of us, especially my husband, a very good scare!!
p.s. We got a pic of the hawk, I'll see if I can post it when i get home from work!
