[HisNameIsHarley]

I just got my first yorkie puppy Harley this past Friday and I've discovered that he has a taste for anything and everything. He picks up anything that will/or will not fit in his mouth, chew on it, suck on it and "try" to swallow it before I see him. I firmly say "No" and remove whatever the article might be (bottle caps, dog hair,lego's, shoe strings.. ANYTHING) from his mouth. This morning he even got a hold of some kind of mint and swallowed it before I could pull it out! Now his breath smells fresh but all his antics are really starting to scare me to death. I'm afraid he's going to get a hold of something and it's going to really hurt him. I vacuume and pick up my house every day to make sure there's nothing for him to snag but no matter how hard I try, he still manages to find something to put in his mouth. He has toys but prefers playing w/ odds and ends he finds laying around. Is this normal behavior? Does anyone have some advice? I've been considering purchasing a containment pen for indoor and outdoor use so there will be a much smaller area for me to have to monitor for stray items he could eat. Is this a good idea? Thanks.
