Runny Nose

In a normal situation, dogs having wet noses is caused by the secretion of oil glands in the canine nose. Dogs with runny noses generally have allergies, caused by many different environmental triggers such as dander, chemicals, dust mites, pollen, grass, etc.

Depending on the severity of the allergy, treatments may range from using specific shampoos and diet changes to steroids and antibiotics. Sometimes, if the underlying allergy cannot be identified, dogs may need to take a series of tests and therapies to help reduce the symptoms.

Ear Infections That Persist

Ear infections in dogs are commonly caused by moisture and organisms in the ear, such as bacteria, fungi, or yeast. These infections can be the result of allergies, injuries, mites, or a foreign body entering the ear, such as dirt, hair, wax, debris, or grass.

If left untreated, these infections can become chronic and may require medical intervention or medication. Certain breeds are predisposed to ear infections due to their anatomy and skin folds. Keeping the ear clean is the first step in the prevention or treatment of these infections.

A mixture of part hydrogen peroxide and part water used to flush the ear every two weeks can help keep the ear clean and healthy. If allergies are the cause, an antihistamine and/or a hypoallergenic diet may be prescribed. If caused by an external factor, such as mites or a foreign body, an anti-parasitic medication or surgical removal may be the best course of action.


Scratching in dogs is usually caused by an underlying allergy or irritation, such as fleas, dust mites, pollen, mold, etc. Allergies are often the underlying cause of scratching symptoms. Some causes of allergic reactions in dogs are inhaling, ingesting, or even directly contacting an allergen.

Treatment for allergies can include antihistamines, steroids, oils, shampoos, and diet changes. Yet, your veterinarian should be consulted to determine the best course of action.

Depending on the cause of the allergy, your vet may recommend a combination of medications and lifestyle changes, such as avoiding certain irritants or using specialized cleaning products. If fleas are an issue, topical or oral treatments may be recommended.

The best way to help limit your dog’s scratching before going to the vet is to practice good preventive care. Regularly groom and brush your pup.

This helps remove any dirt, debris, or parasites that may be causing irritation or discomfort. You can also trim your pup’s nails to minimize contact with the ground and reduce the chances of getting an infection.


Dog sneezing symptoms are not always indicative of an illness. In some cases, they can be a symptom of allergies. The causes of allergic reactions in your pet can be inhaling pollen, mold, dust, or other irritants.

If your dog keeps sneezing, the first step is to take them to the vet for a check-up. The vet will be able to properly diagnose the cause of the sneezing and provide treatment. They may even take a sample to test for germs or allergens.

Depending on the diagnosis, your vet may suggest medication, a special diet, or other treatments like inhalers. If your dog has allergies, the vet may run a series of allergy tests to determine what your pup is allergic to.

Then, provide recommendations on what to avoid and how to manage further episodes. Remember to maintain good hygiene and vaccinate your pup on a regular basis to prevent any further health issues.

Itching and Licking

Dogs can experience itching and licking symptoms due to a variety of types of allergies. This can include environmental allergies such as pollen, mold, and dust mites. Food allergies can also be to blame, as certain protein sources can cause discomfort in some canines.

Flea and bug bites can cause severe itching and licking. Treatment for these symptoms will depend on the cause of the allergy. For environmental allergies, antihistamines or allergen-specific immunotherapy can be helpful.

For food allergies, switching to a novel protein source and eliminating potential allergens can be useful. There are treatments for fleas and bugs with medications, as well as keeping your pet’s environment clean.

Humane treatments may also be helpful, like topical ointments and shampoos, to reduce the symptoms of allergies. In all cases, it is important to work with your veterinarian to identify the specific cause and develop a treatment plan.

Redness of the Skin

One of the most common allergy symptoms that can occur in dogs is redness of the skin. A variety of different things can be the reason, such as allergies to food, environmental irritants, parasites, or even genetics. When a dog has redness on the skin, the hair may become rougher and flaky, and it may also have red, inflamed patches.

Allergies are one of the most common causes of redness in the skin and often require special treatments or medications to help relieve them.

Allergies may involve specific ingredients in their food, or even seasonal allergies can affect some dogs. It’s important to continuously monitor your dog for any changes to its skin or behavior, as this may signal an onset of allergies.


Vomiting can be an allergic reaction to certain food ingredients or medications. Common allergens include proteins, grains, and by-products.
Immediately check your dog’s access to any poisonous substances or trash you may have left out.

Observe the vomitus and take note of any changes in color, texture, and smell. Contact your veterinarian for further advice and to determine whether it is medical or environmentally-related vomiting.

If the condition worsens, take your dog to the nearest vet for an examination. It is important to quickly address the situation since vomiting can be indicative of a more serious medical condition. While consulting your veterinarian, also ask how best to support your dog throughout the episode.

If dehydration becomes a concern, ask your veterinarian about proper fluids that are safe to provide while providing supportive care. Track your dog’s condition and observe if the vomiting stops.

If it persists, take your dog to the vet for further examination and the possibility of medication. Once the allergen has been identified, treatment involves avoiding the offending substance. Most dogs respond to antihistamines or special diet foods to help manage the symptoms, while some may need immunotherapy or avoidance of the allergen altogether.


Dogs can suffer from diarrhea for multiple reasons, including dietary indiscretion, food intoxication, or infection. Allergies can also be a cause of diarrhea in dogs, leading to symptoms such as soft stools and an undesirable smell. Allergies may be related to the food a dog is consuming.

There are a few things you can do to help them feel better. First, reduce your dog’s food intake temporarily so its digestive system can rest. You can give them bland, easy-to-digest foods like boiled chicken or boiled white rice.

Be sure to serve it in small portions several times a day so as to not overwhelm them. You should also give your dog lots of water or an electrolyte solution to keep them hydrated. Limiting your dog’s exercise and preventing them from jumping or playing will reduce the strain on their digestive system.

If your dog’s diarrhea does not improve within 24 hours or is accompanied by a fever or other symptoms, you should seek veterinary care immediately. This will help avoid potentially serious complications like dehydration.

Treatment for allergies in dogs is dependent on the cause. Anti-inflammatory medications, such as corticosteroids, can help reduce inflammation and lessen symptoms. An elimination diet can also be used to pinpoint what is causing the allergies and eliminate them from the canine’s diet.

Pet Allergies Could Get Worse

Pet allergies are an uncomfortable issue to have to deal with. It is important to be well-informed about symptoms so you can get the best treatment.

Investing in pet-allergy-proof covers for furniture, washing your pet often, and using air filtration systems can also help alleviate the problem and improve your pet care routine.

Make sure to speak with your doctor to discuss any necessary steps to take to help manage your pet’s allergies. Taking proper precautions will help keep both you and your pet happy and healthy.
