In short
Stop your dog from wrecking holiday decorations with a bitter-tasting spray, a room set up so the mistake is hard to make, and a trained "leave it" instead of a chase-and-scold routine. Skip the ambush tactics, they teach a dog to hide the habit rather than drop it. Scottsdale and Cave Creek families get through December with the tree intact by removing the opportunity first and teaching the alternative second.
Here are three that hold up, in the order you should try them.
A bitter apple or citronella deterrent spray, applied to the things your dog goes after, gives the chewing an immediate and unpleasant result that has nothing to do with you. Your dog learns the ribbon is bad rather than learning that you are unpredictable.
Two notes. Test the spray on a hidden spot first, because some finishes and fabrics stain. And reapply it regularly, because the effect fades faster than most labels suggest.
The decorations that survive are the ones your dog never gets a free run at. This is the unglamorous option and it is the single most effective thing on this list.
Next step
A PD360 Assessment looks at the whole dog, not just the tree, so you get a real answer instead of another guess.
The old advice was to hide with a spray bottle and startle your dog in the act. Skip it. Ambushing your dog teaches one reliable lesson, which is that decorations are dangerous while you are in the room and interesting the moment you leave. That is how you end up with a dog who only wrecks the tree while you are asleep.
What works is teaching your dog what to do instead, and paying well for it.
Be honest about the underlying cause too. A dog with too little exercise and nothing to do will find itself a job, and in December the tree is the most interesting thing in the room. A fair amount of holiday destruction is really a bored dog problem in seasonal packaging.
If that sounds like your dog, the daily structure and enrichment at DaySchool gives that energy somewhere to go besides the ornaments. If your dog needs the leave it, place, and trade work coached in your own living room, tree included, that is exactly what Private Lessons is built for.
If the chewing does not stop once the decorations come down, you are not dealing with a seasonal problem. Baseboards, furniture legs, shoes, and drywall are the same behavior aimed at a different target, and it rarely resolves on its own. It is worth getting to the root of the chewing before it costs you the furniture.
Partners Dogs has trained 70,000+ dogs in Arizona since 1997, and this exact problem is one of the most common calls we get every December from families in Scottsdale and Cave Creek. We are rated 4.8 stars across 2,000+ reviews for a reason: most of this is fixable with the right plan, not more scolding.
Because being caught in the act, especially by an ambush like a spray bottle, teaches your dog that decorations are risky only while you are in the room. The behavior does not go away, it just moves to whenever you are not there to see it. Removing the opportunity and rewarding a trained alternative work because they change what the dog actually wants to do, not just when it feels safe to do it.
It is a common, low-risk option, but test it on a hidden spot of the ornament or fabric first since some finishes stain or discolor. Plan to reapply every few days, the taste fades faster than most labels suggest, and a spray a dog has stopped noticing will not stop the chewing.
That points to a broader chewing habit rather than a seasonal one, and the tree was just the most interesting target in the house that month. Baseboards, furniture, and shoes are the same behavior aimed elsewhere. A PD360 Assessment can identify whether it is boredom, anxiety, or something else driving it, so the fix targets the actual cause.
Beyond the holidays
If the tree was just the easiest target, Behavior Camp resets the habit at the source so next year is not a repeat.
