My lab is now 14 weeks and in the last week or two I've noticed she has really started to chew through toys like crazy. Are Labradors considered power chewers? I'm wondering if this is normal. If I give her a plush toy, she will very intensely focus on an ear or a tail and chew through it until I'm pulling bits of fabric and stuffing out of her mouth. She is still not able to make a dent in some of the stronger nylon/rubber tows but doesn't show much interest in those yet. The fake (non splinter) wood toys seem to be my only saving grace right now. I'm just surprised her bite has developed so fast (glad she's not biting me anymore, at least not much). Again, just curious, is this normal for a lab?
