I can get behind a mask for outside but in the house this is something you are going to have to work on. Pick up EVERYTHING, get on the floor and look at things like you would as if you were baby proofing. Buy toys that are for tough chewers which know you will pay about 20 bucks per toy. Don't give any toys that have squeakers in them. Stick with the training, your baby is still young and going through a lot of changes.. things start to settle down around the 1 year mark, and even more so after they are neutered.This is the mask I use for both of my babies outside because I have one that likes to eat everything.Dog mask.They can breath easily, even drink water through it.
