I ' m on Narwhal though . best app ever <| sep |> I don ' t see how paying the same amount as everyone else is cheating Frontier out of anything , when the reason for the discrepancy is that they haven ' t bothered to adjusted their shop prices to match the currency rates . Also when I have a number of disagreements with the way the shop works , but finally gave in and bought some things anyways . <| sep |> I would recommend what my trainer calls the bubble game . Essentially there is a magic perimeter around whatever object you ' ve said no to . If your dog already has a good out type command you can skip the rest of this paragraph . If not how the bubble game works is you use body language and verbal correction to keep your dog away from a toytreat . Only after they respect the boundary are they allowed to have their reward . To start you place a treat between your feet , and then slowly walk towards the dog while giving a verbal correction . The dog may try to run around you , at which point you step to the side and block them . Look forward , and stay patient and calm . Eventually the dog will accept that they cant run over and get the treat . The first time I did this it took probably five minutes . But wait ! We aren ' t done ! Now you want to back away from the dog , so that you aren ' t the physical boundary . If they move towards the treat you give them a verbal correction first , then if that didn ' t work it ' s back to physically blocking them . The goal of this is to get the treat in the middle of you and the dog while the dog accepts that they have to wait where told . Once they do this , they can get up and grab the treat . This seriously worked wonders with my border collie . So once your dog has a concept of out you can apply the bubble principle to the tree , stocking , whatever it is that doggo needs to stay out of . If you see the dog looking interested and snooping around , give a verbal correction the same one you used in the bubble game . Once a dog is good at this that will be enough , and they can learn to lay next to something they want without getting into it . Chances are when you start , your dog will hesitate for a minute and then go back to being overly interested in the forbidden fruit . So this time when you offer a correction , it ' s going to come with a boundary . If the dog can ' t avoid chewing close by , the dog will have to be a few feet away . Tell the dog out or use the bubble game , whatever method you ' ve used to get to this point . Each time the dog goes to get into the tree , the boundary gets bigger . When you start the dog might end up in a room by himself or completely down the hall . Since you have a puppy , I would highly recommend setting your dog up for success by crating when you aren ' t home and keeping the dog away from the tree until you are confident there won ' t be issues . If your dog never learns that tearing up christmas presents is fun it ' ll be a lot easier to stop it from happening . If your dog is super ultra interested in the tree you might have to get a doggy gate or keep your dog leashed , and then introduce your dog to the tree in ten minute training sessions . This same concept can be used for anything , including cats that ' s what I ' m using it for right now . Another technique that can be used for specific items the dog likes to chew think shoes , a specific christmas decoration is to place the item next to the dog while you are watching and offer a gentle correction when they go to chew it . Eventually they will learn that it is off limits and not to be touched with teeth .
