Why Is My Dog So Itchy? What Pet Parents Should Know About Fall Allergies

Posted on 09.07.2026

As the leaves start changing, many pet parents notice something else changing, too.


Their dog won't stop scratching. Maybe it's constant licking at their paws. Rubbing their face across the carpet. Scratching their ears. Or chewing at their legs every chance they get.


While spring often gets the spotlight for allergies, fall can be just as challenging for many pets. Here's what could be behind the itch and how you can help.

 

Quick Answer

Fall itching isn't always caused by seasonal allergies, so we need to figure out the real reason behind the extra scratching. Environmental allergens, food intolerances, fleas, dry skin, and even skin infections can all make dogs uncomfortable.


Finding the cause is the first step toward helping your pet feel better.

 

Why Dogs Get Itchy in the Fall

Several things can trigger itching this time of year.


Common culprits include:

  • Weed pollens like ragweed
  • Mold spores from damp leaves
  • Dust mites as pets spend more time indoors
  • Flea bites
  • Dry, changing weather
  • Food intolerances that become more noticeable over time

 

Because many of these causes produce similar symptoms, it isn't always obvious what's behind the scratching.

 

Signs Your Dog May Be Dealing With Allergies or Skin Irritation

 

Every dog is different, but common signs include:

  • Constant scratching
  • Excessive licking or chewing at paws
  • Red or irritated skin
  • Ear irritation or frequent ear infections
  • Hot spots
  • Hair loss from excessive scratching
  • Face rubbing on furniture or carpet

 

If symptoms are severe, persistent, or your pet develops sores or infections, it's important to find the root of the symptoms.

 

Could It Be Diet Related?

Sometimes food intolerances can affect a dog's skin just as much as their stomach.


While environmental allergies are common during the fall, some pets react to ingredients in their diet year-round. In those cases, seasonal changes may simply make existing skin issues more noticeable.


If you've noticed ongoing itching, recurring ear problems, digestive upset, or hot spots, it may be worth taking a closer look at your dog's nutrition. Chat with a Two Bostons Team Member for a personalized one-on-one Nutrition Consultation. We'll help you compare options, understand ingredients, and build a nutrition plan that works for your pet.


Nutrition Can Support Healthy Skin

Healthy skin starts from the inside out.


Diets rich in quality protein and omega fatty acids help maintain the skin's natural barrier, while targeted supplements can provide additional nutritional support for healthy skin and a shiny coat.

 

Open Farm Skin & Coat Chews

Open Farm's Skin & Coat Soft Chews are designed to support skin and coat health with omega-rich cod liver oil, salmon oil, and antioxidant-rich blueberries.


Why we like them:

  • Supports healthy skin and a shiny coat
  • Rich in Omega-3 fatty acids
  • Made with traceable, non-GMO ingredients
  • Easy daily soft chew

 

For many dogs, supporting skin health through nutrition can be an important piece of the puzzle.

Help Soothe the Itch

Sometimes your dog just needs a little relief while you work to identify what's causing the problem.

 

Nootie Itch Relief Medicated Spray

Nootie's Itch Relief Spray helps soothe irritated skin with veterinarian-strength active ingredients.
 

Why we like it:

  • Helps calm itchy skin
  • Supports healing of irritated areas
  • Safe for dogs and cats
  • Can be used alongside topical flea and tick products
  • Free of parabens, SLS, harsh dyes, and other unnecessary additives

 

It's a great option to keep on hand for temporary relief while you work with your veterinarian or develop a longer-term plan.

Don't Guess. Start With the Cause.

Because itching can have many different causes, there's rarely a one-size-fits-all solution.


Your pet may benefit from:

  • A nutrition change
  • More skin-supportive nutrients
  • Flea prevention
  • Environmental management
  • Veterinary treatment for allergies or infections

 

That's why it's so important to look at the whole picture instead of simply treating the itch.

 

Final Thoughts

If your dog seems itchier every fall, you're not alone.


Whether the cause is seasonal allergens, food intolerances, or something else entirely, identifying the source can help your pet feel more comfortable.
