Try Using Lemon Juice And Water

If you do not want to purchase bitter spray, there are similar things you can make at home. One home remedy that you can use to keep your pet from licking objects is mixing lemon juice and water. Simply mix two parts lemon juice with three parts water into a small spray bottle. This mixture will make an unattractive taste for your dog to try and lick, sort of like sour candy without the sweetness. You can also try using cayenne pepper or vinegar as another deterrent for excessive licking.
Elizabeth Collar

The Elizabeth collar is a cone-shaped device that effectively keeps your dog from licking or chewing on an object. This special collar has been specially designed to stop pets from doing this by blocking their access to the objects they want to lick. The Elizabeth collar forces dogs to circle it rather than instantly stopping them in a place like some other products. It’s also easier for dogs to learn with the Elizabeth collar because it doesn’t cause as much stress as other devices.
Get Them Plenty Of Exercise

Make sure your dog gets about 30 minutes of exercise per day, even if it’s just a short walk around the block. Dogs and other pets that get enough exercise will be more satisfied, and they’ll tend to lay off items that they shouldn’t lick or chew on. Your pet will also be much happier when he doesn’t have excess energy burning up inside him.
Another advantage of giving your pet enough exercise is that it will tire them out, so they’ll sleep better at night. A tired dog won’t be quite as likely to wander around the house in hopes of finding something fun to do, and this makes a big difference when you’re trying to train him not to lick certain objects.
Hire A Behaviorist

Although there are plenty of things you can do on your own to train your pet not to lick or chew on inappropriate items, it can be helpful to hire a professional behaviorist. You might notice some behaviors that you don’t know how to handle, and having someone like this will help you immensely when training your dog. Whether it’s something as simple as getting the right tools or something more complex like making sure you’re doing everything in the proper order, hiring a behaviorist is often worth the money because it’ll make everything go much more smoothly.
Get Medication

If all else fails, it may be time to turn to medications. Some pets can get so obsessive about licking and chewing on things that they won’t even respond well to anything else at first. This is especially common if the behavior has been going on for several months or more, and it will take a lot of time before you start seeing improvement with other methods. Your vet should prescribe an anti-anxiety medication that should be very effective in helping your dog relax while discouraging him from engaging in such behaviors.
Eliminate Stress As Much As Possible

Dogs under a lot of stress have a higher chance of licking and chewing things they shouldn’t. If you can, take steps to improve your dog’s living conditions, so he has less reason to be stressed. This may involve making sure there aren’t loud noises or other animals around him, for example. If you take the time to reduce your pet’s stress as much as possible, it will make it easier for him to alter his behavior toward what he can and cannot lick.
Conclusion
When all else fails, make sure you are patient with your pet. This may be frustrating, but it won’t last forever, especially if you’re consistently training him to do something else instead of licking the object he shouldn’t. Think of ways to keep him busy while you can’t watch him or find different strategies that work for both of you.
There are many steps you can take to stop your dog from licking or chewing on things he shouldn’t. Although some methods are more effective than others, it’s not too difficult to find something that will work for your pet. If you’re having trouble with this behavior, make sure you try these tips first before resorting to professional help or medication. If all else fails, there is no shame in asking for assistance!
