Congratulations, now that you've bought your puppy home. We need to talk about puppy proofing. You want to be sure that you're not just making sure that you have the dog in a confinement space. There are a few other things we need to take into consideration. Sometimes I'll actually have people actually get down on the floor and look around the perimeter of their apartment or their house to see: Are there wires hanging; is there fringe on the carpet that you're missing, or something along those lines?
You want to make sure that you're avoiding the dog doing anything destructive to your property, but also that you are keeping the dog safe. Where, chewing the fringe on a rug might be a drag, because you like that rug; chewing on a wire could be a real tragedy for your dog and for you as well. So, obviously, having some sort of confinement space and plenty of appropriate things for the dog to chew is a good starting point so that you are getting the dog addicted to chewing chew toys as opposed to being in search of things to destroy around the house.
Also, he's never unsupervised. You never want to leave your dog unsupervised to roam around the living room and kitchen. Anytime he's out of his space here, you're both cognitively and physically aware of him. As far as being sure that he is not chewing anything, you may want to roll up the carpets, especially if your dog is using a wee-wee pad. Sometimes, a wee-wee pad and a carpet are not that different to a dog. So, bath mats, wee-wee pads, things like that, you're taking them all up. They do sell deterrents to stop dogs from chewing on wood, like the corners of your moldings and things like that. Things like bitter apple spray and stuff, but a lot of times just vigilance will do the trick in some cases. Be sure that the dog does not have anything in their enclosure or too close to their enclosure. If you were to have something like this set up, you want to make sure that it is not set up right next to the computer outlet with all of the computer wires hanging out.
Make sure that you are getting down on the dogs level, taking a good look around. What is there available that the dog could chew that could be potentially dangerous for him or just a drag for you? We want to make sure that we're keeping these guys safe and keeping your house in order.
Alright, those would be the first steps to puppy-proofing your house. Good luck.
