Symptoms of Allergies in Dogs and How to Provide Your Pet with Relief

Allergies in dogs occur when their immune system reacts to everyday substances in their environment, food, or even seasonal changes. The symptoms of allergies in dogs often appear as skin irritation, persistent itching, ear infections, or digestive upset. Because dogs cannot tell us what’s bothering them, recognizing these signs early makes a big difference in their comfort and quality of life. If your pet is scratching more than usual, licking their paws excessively, or experiencing chronic ear issues, allergies may be the cause.

This blog explores the most common symptoms of allergies in dogs, the different types of allergies they may experience, and how professional veterinary care can provide relief. By the end, you’ll know when it’s time to schedule an appointment with Manchester Animal Hospital to get your dog the help they need. Call (978) 526-9500 or book an appointment online today.

 

 

Understanding the Symptoms of Allergies in Dogs

When dogs develop allergies, their bodies respond with visible and often uncomfortable reactions. These symptoms can affect the skin, ears, digestive system, and even their behavior. Because many signs overlap with other health conditions, it’s important for a veterinarian to evaluate your pet.

Common Physical Symptoms

• Persistent scratching or chewing at the skin
• Hair loss or thinning coat
• Red, inflamed, or scaly skin patches
• Chronic ear infections or head shaking
• Watery eyes or nasal discharge
• Frequent paw licking or chewing

Behavioral Changes

Dogs dealing with allergies may become restless, anxious, or irritable. Constant discomfort can interfere with sleep, play, and their daily routine. If your dog seems unusually unsettled, allergies could be the reason.

Digestive Issues

Some dogs with food-related allergies may show signs such as:

• Vomiting
• Loose stools or diarrhea
• Excessive gas
• Decreased appetite

Types of Allergies in Dogs

Not all allergies look the same. Understanding the type of allergy your dog may have helps explain the symptoms you notice at home.

Environmental Allergies

These are among the most common and often seasonal. Dogs may react to:

• Pollen
• Grass
• Mold spores
• Dust mites

Environmental allergies typically cause itchy skin, ear infections, or watery eyes.

Flea Allergies

Dogs that are allergic to flea saliva can develop intense itching from even one bite. This condition, called flea allergy dermatitis, often leads to skin infections if not addressed promptly.

Food Allergies

While less common, food allergies can cause both digestive upset and skin irritation. Proteins such as chicken, beef, or dairy are frequent triggers.

Contact Allergies

Some dogs may react to shampoos, cleaning products, or fabrics. Symptoms usually appear where the skin touches the irritant, such as the paws or belly.

Diagnosing Dog Allergies

Because the symptoms of allergies in dogs can mimic other health concerns, a thorough veterinary exam is essential. At Manchester Animal Hospital, our team uses a combination of history, physical examination, and diagnostic testing to identify the source of your pet’s discomfort.

Physical Examination

Your veterinarian checks for inflamed skin, signs of infection, and other visible issues that point toward allergies.

Diagnostic Testing

• Skin tests may help pinpoint environmental allergens.
• Blood tests can measure allergic responses.
• Elimination diets are often used for food allergies to identify problem ingredients.

By narrowing down the cause, we can create a treatment plan tailored to your dog’s specific needs.

Veterinary Treatments for Allergies

Once allergies are identified, your veterinarian will recommend professional treatments to relieve symptoms and improve your pet’s comfort.

Medications for Relief

Dogs may benefit from prescription medications designed to reduce itching, inflammation, and allergic reactions. These can include oral tablets, injections, or topical treatments.

Specialized Diets

For food allergies, a prescription or hypoallergenic diet may be recommended. These diets reduce exposure to allergens and help improve digestive and skin health.

Flea Control

Preventing flea bites is critical for dogs with flea allergy dermatitis. Year-round flea prevention is one of the most effective solutions.

Long-Term Management

Some dogs require ongoing allergy care. This might include immunotherapy (allergy shots), medicated shampoos, or regular check-ins with your veterinarian to monitor progress.

How Untreated Allergies Impact Dogs

Ignoring the symptoms of allergies in dogs can lead to chronic problems that affect their overall well-being.

Secondary Infections

Persistent scratching often damages the skin, allowing bacteria and yeast to cause painful infections. These infections can become recurrent if the underlying allergy isn’t treated.

Chronic Ear Problems

Dogs with allergies often develop recurring ear infections that may lead to hearing issues if left unmanaged.

Reduced Quality of Life

Allergies can make dogs restless, uncomfortable, and less playful. Addressing these issues helps restore their energy and happiness.
