Itchy Pet? Understanding Allergies and How Main Street Veterinary Can Help

If your furry friend is constantly scratching, licking, shaking their head, or dealing with tummy troubles, allergies might be the cause. The good news? Allergies are common in both dogs and cats, and while they can’t be cured, they can be managed successfully.

At Main Street Veterinary Hospital, our goal is to keep your pet comfortable and help your whole family enjoy peaceful, itch-free nights again.


What Do Pet Allergies Look Like?

Allergies don’t look the same in every pet, but here are some common signs we see at Main Street Veterinary Hospital:

In Dogs (and some cats): See below for photos as examples
 

  • Itchy skin (scratching, chewing, licking)

  • Red or irritated skin

  • Recurrent ear infections

  • Hair loss

  • Hot spots

  • Vomiting or diarrhea

 


Cats often show allergies differently, which can make them trickier to spot:

  • Small scabs or bumps on the skin

  • Over-grooming that leads to hair loss

  • Severe itching around the head and neck

  • Swollen or irritated skin lesions

  • Allergies can appear seasonally, or persist year-round.

 

 

Types of Allergies in Pets

🌿 Environmental Allergies (Atopy)

  • These are reactions to pollen, grass, dust mites, mold, and other environmental triggers.

  • Can be seasonal or year-round

  • Often begins between 6 months and 4 years of age

  • Can worsen over time if not managed

  • Very common in North Carolina due to our long allergy seasons

 

At Main Street Veterinary Hospital, we offer allergy testing to identify environmental triggers. This helps determine if allergy injections (immunotherapy) could improve your pet’s quality of life. While injections take time, up to a year, to show full benefit, they can significantly reduce flare-ups in many pets. See below for an example of a patient with significant positive allergy results.

 


 

️ Food Allergies

  • Food allergies can develop at any age but are most common in very young or older pets.

  • Typically cause year-round symptoms

  • Diagnosed through an 8–12 week prescription diet trial

  • Over-the-counter diets aren’t reliable for testing due to cross-contamination

 

Prescription diets may include:

  • Hydrolyzed protein – broken down so the immune system doesn’t recognize it

  • Novel protein – a new protein source like rabbit or duck

  • Pets can have both food and environmental allergies at the same time, so a thorough evaluation is key.

 

Why We Always Start With Parasite Prevention

  • Before we diagnose allergies, we rule out parasites. Fleas, mites, and intestinal parasites can cause similar symptoms:

  • Even one flea bite can trigger intense itching in an allergic pet

  • All pets in the home need year-round flea prevention

  • Flea infestations can take up to 3 months to fully clear

  • Treating only one pet isn’t enough

  • Parasite prevention is always the first step in keeping your pet comfortable

 


Secondary Infections: A Hidden Cause of Discomfort

  • Pets with allergies often have a weakened skin barrier, making them more susceptible to bacterial and yeast infections:

  • Infections can make itching worse

  • Allergy medications alone won’t resolve them

  • Antibiotics or antifungal treatments may be needed

  • Yeast infections, in particular, can cause rapid and severe discomfort.


Treatment Options at Main Street Veterinary Hospital

Every allergic pet is different, so we create customized management plans. Treatments may include:

  • 💊 Fast-Acting Oral Medications ○ Daily medications that quickly relieve itching and inflammation.

  • 💉 Cytopoint Injections ○ Given every 4–8 weeks, many pets feel relief within 1–2 days.

  • 🕒 Long-Term Oral Medications ○ It takes several weeks to reach full effect, but is great for ongoing management.

  • 🌱 Allergy Injections (Immunotherapy) ○ Based on allergy testing, these long-term treatments can reduce flare-ups over time.

  • 🛁 Topical Therapy ○ Shampoos, mousses, sprays, and wipes help maintain skin health and manage flare-ups.
