Is there some kind of spray that will keep puppies from chewing on things they suppose to?

There are a number of sprays you can use to keep puppies from chewing on things. These sprays typically contain a bitter-tasting or foul-smelling substance, which deters puppies from chewing. Common ingredients in these sprays include:

* Apple cider vinegar

* White vinegar

* Citronella oil

* Eucalyptus oil

* Lavender oil

* Tea tree oil

In addition to using a spray, you can also try other methods to discourage your puppy from chewing, such as:

* Providing them with plenty of appropriate toys to chew on

* Removing items that your puppy might be inclined to chew

* Supervising your puppy at all times

* Training your puppy to sit or stay when you don't want them to chew

With patience and consistency, you can train your puppy to stop chewing on things they shouldn't.
