Some conditions cannot be prevented but some can.  Dogs should be on monthly flea and tick preventative medication. This will prevent flea allergy reactions and irritated skin. It is important to prevent your dog from being exposed to toxic chemicals. If you spray your lawn with pesticides, your dog should not be allowed to walk on the grass until the chemical is dry. The same thing goes for recently cleaned floors or carpets. Dogs should be provided toys, attention and daily exercise.  Additional activities may help prevent a dog from feeling bored or anxious.
Available everywhere and relatively inexpensive, rawhides can be a good chew option for some dogs. Plenty of dogs chew rawhides without incident. However, some dogs end up with bits of rawhide lodged in their “windpipe” (trachea), causing choking; or big pieces in their stomach, causing a digestive obstruction. If your dog actually chews the rawhide, rather than biting off and gulping large chunks, they’ll likely be OK — they may even get some teeth-cleaning benefits. This is especially true if you pick up a VOHC-approved “dental rawhide.”
Rope toys are generally safe for the right types of chewers. However, plenty of dogs have undergone surgery to remove strands of rope from their stomach or intestines. All “foreign body” digestive obstructions are dangerous (and distressing) for dogs, but the linear foreign body type that comes from strings that make up rope toys is particularly dangerous. That’s because linear foreign body obstructions can saw through a dog’s intestines with severe, painful, and expensive consequences. If you let your dog chew on a rope toy, never let them do so without observation, never leave it laying around, and always take it away if you see the dog pulling out and eating the strands.
THE LONELY DOG is one that is left alone for long periods of time in an unstimulating environment. These dogs chew out of boredom. To remedy the situation several things are in order. First make sure your dog is well exercised. An aerobic work-out is required for older puppies and adolescents. Second, provide your dog with a place that he can have all to himself. Dogs possess a denning instinct; let it work for you. The best way to confine a dog is with a kennel crate. A small bathroom or a kitchen area may do, if the dog is adverse to crating. However, there are many chewable objects in these rooms including flooring and cabinetry.
Give him a chew toy instead. If your dog attempts to chew on an inappropriate item while in your presence, simply interrupt the behavior and re-direct him to an appropriate chew toy. It can be helpful to have a stuffed Kong toy in a Ziplock bag in your freezer – so you can quickly produce it when needed. Many pups have certain times of day when they are more likely to chew, so you can head this behavior off at the pass if you choose this time of day to give the dog an approved chewie.
We just got a 9 yr old shiz tzu. He’s obsessively biting, chewing, and grunting over his feet and his butt. His previous owner had a prescription for anxiety meds and I gave him half of one pill (dose age) and have just about doused him with anti itch spray. Bathed him and no good! Food allergy maybe? He eats pedigree small bites, but my rat terrier had a similar problem and it cleared up after we changed his food. Any suggestions?

Chewing is a natural behavior for dogs. They use their mouths to explore the environment in the same way that humans use their hands as investigative tools. Irksome and sometimes expensive destructive chewing usually takes place when the owner is not with the dog. Therefore, correction when the dog starts or is in the act is impossible. The chewing can then become a compulsive behavior when the dog is lonely, bored, stressed or anxious.
Any dog can bite if she feels threatened or nervous. But socializing a dog early teaches her to feel relaxed around people. Gradually expose her to different settings so she will feel safe. Spend lots of time with her so she learns to trust people. Always watch for signs that your dog is uncomfortable and then do what you can to make her feel better. Be especially careful around kids and food. If despite your efforts your dog is a biter, see your vet or your pet's trainer for help.
Dog treats serve a number of useful purposes. They help satisfy your dog’s need to chew, and they’re an indispensable part of training, especially for food-motivated pups.

Long-lasting dog treats are great for special occasions. They can help reduce stress as your dog chews or keep her occupied when guests visit.

“Chewing and licking can disrupt the normal skin barrier and the normal skin defenses,” Dr. Pachel says. Dampness from saliva can lead to yeast and bacterial infections, particularly for dogs with thick fur that retains moisture. And repeated friction from a rough tongue can rub off fur and cause acute moist dermatitis (hot spots) and lick granulomas (skin lesions).
The physical causes may need addressed by your vet. Your dog may need a dental cleaning or have a gum issue. The psychological causes may need addressed by a behaviorist if the above remedies do not seem to work. A dog behaviorist may help you learn tecniques to better train your dog and may recommend some medications. Do not try to address behavior issues on your own. For instance, if you tell an anxious dog to stop chewing furniture it may start chewing it’s own paws or chasing its tail instead.

Boredom, anxiety, frustration, or excess energy may be common triggers. Some dogs suffer from separation anxiety and once left alone at home will resort to chewing half a house apart. If you recognize any of these behavior issues try to address them properly. A dog behaviorist may be necessary for severe cases. However, many times all it takes is taking your dog out more to release the extra energy and help relieve the boredome. This is usally the path towards happier and more relaxed dog.
These chews — which include things like Greenies®, Dentastix™, Brushing Chews®, VeggieDent® Chews, and others — don’t last very long and therefore won't provide much long-term satisfaction for your dog’s chewing needs and desires. That said, they can provide some help with your dog’s short-term chewing desires and can even provide some help with their dental and oral health, as many of these chews can help minimize or slow plaque and/or tartar buildup. Just be aware that they can also add a fair number of calories to your dog’s diet and should only be given in moderation, especially to a dog with a weight problem. Additionally, these can become a choking hazard or digestive obstruction if your dog bites off and swallows large chunks - so always observe how your dog is chewing and interacting with these and take them away if they're not chewing well or safely enough.

Chewing is a perfectly normal behavior for dogs of all ages. Both wild and domestic dogs spend hours chewing bones. This activity keeps their jaws strong and their teeth clean. Dogs love to chew on bones, sticks and just about anything else available. They chew for fun, they chew for stimulation, and they chew to relieve anxiety. While chewing behavior is normal, dogs sometimes direct their chewing behavior toward inappropriate items. Both puppies and adult dogs should have a variety of appropriate and attractive chew toys. However, just providing the right things to chew isn’t enough to prevent inappropriate chewing. Dogs need to learn what is okay to chew and what is not. They need to be taught in a gentle, humane manner.
