Ok, so this might be a silly question, but should I be worried about my puppy's obsession with sticks? Bella is a 2 month old Lab mix. She's an absolute sweetie. She goes to work with me and we have a fenced in backyard there. There's a million sticks on the ground and she is constantly chewing on them. She has toys to play with, but she'd prefer to either chase me or chew on sticks. Should I not let her do this? Thanks.
