We adopted a 9 month old lab/pit bull mix a few weeks ago. He stays in the garage while we are at work during the day. He has a crate in the garage but I don't lock him in it. There's not much in the garage for him to get into. However, he did get into a bundle of shims (small wood "sticks"
;) and chewed up quite a few of them. I'm not sure if he actually ate the wood or just chewed on it. I picked up the mess and the remaining shims and put them out of his reach. But then last night he started eating sawdust. My husband and I were in the garage working on building him a dog house and hadn't swept up the sawdust yet. Why would he be doing this? Should I be concerned?
He has lots of things to chew on (bones, kong toy, etc) so I'm not sure why he would be doing this.
