Skin Infection

A skin infection isn’t uncommon in dogs. Parasites or bacteria cause most skin infections. If your dog scratches himself too much, it may be a sign of a disease.

Sometimes this itching can become quite severe. Your dog may scratch his skin raw. If this occurs, it could lead to an open wound or an injury that will require medical treatment. If your dog is itching so much, he rubs his body against things that can irritate the skin. This irritating action can cause the itch to get worse, which can lead to a severe problem.


If your dog is female, her pregnancy can cause her to start itching herself. This is because of the added weight that a pregnant dog is carrying. As the dog eats, the extra weight puts pressure on her spine, which causes her to rub herself. If the owner isn’t paying close attention during this time, the excessive scratching could lead to an infection.

Dog’s nail

There are a few other factors that will contribute to your dog’s constant scratching. Sometimes a dog’s nails get long, making it difficult for him to walk due to pain. Other times, the nail may grow inward, which is painful for your dog. This can lead to different types of pain, such as arthritis.


If your dog stays bored most of the time, he may be scratching because he feels restless and wants something to do. You can give him a toy to play with or ask him to perform a command for you. Once he becomes accustomed to you giving orders, he will stop scratching.

Mites and Fleas

The first reason why the dog scratches so hard is that it is not comfortable being used to having his paws on furniture or other objects around him. The second reason why the dog constantly scratches is due to the mites and fleas. The dogs are susceptible to this kind of stuff, and they always scratch their paws as a reaction. This is just natural.

Sometimes dog feels threatened

One of the main reasons why the dog constantly scratches is because it feels threatened. If a dog is scared, it will rub his or her body against furniture, doors, other dogs, cars, etc. This serves as protection from things such as these. Dogs use their nails to mark their territory, so they feel more secure when doing this.


To prevent your dog from doing this, you need to give him a regular trimming of his nails. Get him used to get his nails trimmed periodically and be patient as he eventually gets used to it. The best time to do this is about a week after you take him home from the shelter. It would be easier to start with the first week of his new home as his body still has some feelings about his new environment.

With all these facts in mind, the best solution is to teach your dog to stop scratching. You don’t have to use anti-nail solid biting remedies; all you have to do is teach your dog how to respect other things and not mark their territory with their nails. That’s right. You don’t have to resort to sprays, powders, or creams. All you need to do is make your dog understand the real reason behind scratching and respect other people and things in their surroundings.

When you understand why the dog constantly scratches, you’ll be able to stop them in their tracks. Just make sure you do this gently, especially if your dog has long nails. There are many other methods of training your dog to stop this undesirable behavior, too, such as positive reinforcement.
