With different environmental and physical conditions affecting dogs at different times of the year, at different times of their lives, and even times of day, the dog's health can suffer. Allergies, dry spells, humidity, high and low temperatures, and rain may be damaging the dog’s coat and irritating the dog’s skin. When you encounter a bump under your dog's fur (not a lump), there are many things what that could be.

When your pooch is developing bumps on their skin, it can be caused by any of these or more. Sometimes it may be a combination of different medical issues and situations. As the dog's condition worsens, it is vital that you identify the possible causes that way you can reduce the problems that are affecting your pet.

With the increasing amount of bumps surfacing on your dog in different sizes and shapes, it may become alarming, and you may wonder if there is a more significant health issue behind them. To be completely sure, it's best to visit your veterinarian to check what the bump actually is, because sometimes this may require a test.

Luckily, most times, these bumps under your dog's fur are nothing too serious and typically may be caused by skin sensitivities and issues that can be treated at home without the need to visit a vet unless the condition worsens. Here are five of the most common causes of bumps on a dog's skin that aren't related to tumors.

1. Canine Atopy

Canine atopy refers to allergens that dogs may be exposed to by breathing them in, also know as inhaled allergens. These allergens can include pollen, dust, and mold. A dog may show symptoms of distress after inhalation and should be treated immediately. Benadryl can be used to treat the reaction, but a vet should be contacted beforehand to obtain the information regarding the proper dosage for your dog.

Signs that your dog may be suffering from canine atopy are itching, scratching, rubbing, hair loss, greasy and flaky skin, foul odor, and excessive chewing. Your pooch will develop bump-like welts from constant skin irritation which can be found near the paws, groin, and armpits.

2. Fleas, Mites and More

Fleas, mites, and other skin parasites and bugs can give dogs serious skin problems and overall health issues. Bumps may be the result of a bite from the critters or an allergic reaction caused by the bites on the dog's skin. Depending on whether the bumps are caused by the insect bite alone or if it is an allergy from the dog will determine the method of treatment, although if it is caused by an allergic reaction, it is usually determined after the critters are treated and removed.

First, the issue should be treated as if the bumps are caused by the bites alone. There are medicines and sprays that will allow you to purge your pet, home, and yard of the critters. After the critters have been removed, it is essential that the dog is placed on a preventative medication to keep the pests away. If the reaction is determined to be an allergic reaction, topical medication can be purchased and applied at home. If the reaction does not subside, then approach the vet about treatment options.

3. Dermatitis

Dermatitis is a reaction of the skin due to the dog’s interaction with the nearby environment. These interactions can be with grass, plants, dirt, bugs, water, and any other chemicals or products that are used in the yard or home. Although it is a reaction to the environment, it is not necessarily an allergic reaction.

Canine dermatitis is usually caused by a change in the environment or an addition to the environment, meaning the reaction is the dog attempting to adjust to the new change. A common sign is the development of small bumps on the skin that become irritated and change into hot spots.

The dog's reaction will typically go away on its own unless it has progressed into hot spots. A hotspot is a lesion on the exposed skin that is commonly caused by moisture, which can be rain or from the dog continually licking the wound. If a hot spot is noticed on the dog, a vet should be contacted right away. An excellent way to prevent and treat small hot spots is to use a benzoyl peroxide shampoo.

4. Skin Allergies

The realization that the dog may have a skin allergy is one that happens for many dog owners. Bumps and rashes are a visible sign of skin allergies on a dog. Dogs that are poorly bred are more likely to develop skin allergies versus dogs that are properly bred and cared for.

Skin allergies can be hard to deal with, as the symptoms seem to appear out of nowhere and without an apparent cause. With intense observation and using research of common causes, it may be possible to discover the cause and remove it from the environment. A vet can also be contacted and diagnose the issue so that it may be prevented in the future. Minor skin itches may be treated with hydrocortisone products.

5. Food Allergies

Food allergies may seem just as challenging to identify as skin allergies. The appearance of bumps suggests that the problem lies on the outside of the skin when there seem to be no obvious internal causes. Food allergies show all the same symptoms as other allergy types, causing slight confusion when attempting to determine its origin.

Your Dog Has Bumps Under Her Fur - 5 Things This Could BeThe usual cause of food allergies is the consumption of food that contains a specific ingredient that the dog is allergic to. The key to combating the allergy is to identify the ingredients included in the dog's current diet and to shop for new food that does not include one of the ingredients. If the dog continues to show signs of allergies, then you need to try another brand of food that includes different ingredients. Repeat the process until a brand is found that does not cause an allergic reaction within the dog.

Some dogs will randomly develop bumps on their skin due to a random occurrence. These bumps can usually be treated at home with a quick shampoo and anti-itch medication. The best way to determine the cause of the bumps is to attempt the treatment at home before moving on to find other causes. Most times, the bumps will disappear and no longer be a problem for you or the dog.
