As the weather warms up in Oregon, many pet owners start to notice a familiar pattern—more scratching, more licking, and pets that just seem uncomfortable in their own skin.

If that sounds familiar, there’s a good chance your pet may be dealing with seasonal allergies.

At The Pet Clinic, we see a noticeable increase in allergy-related concerns every spring. The good news is that allergies are very common—and with the right care, they can be managed effectively.

What Causes Spring Allergies in Pets?

Spring allergies in dogs and cats are typically triggered by environmental allergens like pollen from grass, trees, and weeds, as well as mold spores. As these allergens become more active in warmer weather, many pets begin to show symptoms.

Oregon—especially the Willamette Valley—is known as one of the largest grass seed–producing regions in the world, meaning pets are exposed to particularly high levels of grass pollen. As dogs and cats spend more time outside in the spring, this increased exposure often leads to itching, licking, and skin irritation.

Some of the most common grass pollens that trigger allergies in dogs include:

  • Ryegrass and fescue
  • Orchard grass and timothy grass
  • Kentucky bluegrass

These grasses are commonly found in local lawns, parks, and open spaces, making exposure hard to avoid for many pets.

In addition to grasses, tree pollens from species like oak, pine, and juniper can also contribute to seasonal allergies. Because of this combination, pets in Oregon often experience more noticeable allergy symptoms compared to other regions.

What Do Pet Allergies Look Like?

Unlike humans, who tend to experience sneezing or watery eyes, pets usually show allergies through their skin—leading to itching, licking, and irritation. Most pets with allergies don’t just “scratch a little”—they can become noticeably uncomfortable.

Common signs include:

  • Persistent scratching or itching
  • Licking or chewing at the paws
  • Red, irritated, or inflamed skin
  • Recurring ear infections
  • Hair loss or thinning coat

Some pets may also develop hot spots, which can worsen quickly without treatment.

Why Is My Dog So Itchy in the Spring?

One of the most common questions we hear is, “Why is my dog suddenly so itchy?”

During the spring, pollen settles on your dog’s coat and skin every time they go outside. Over time, this exposure can trigger an allergic reaction that leads to inflammation and persistent itching.

Many dogs focus their discomfort on their paws, ears, belly, and underarms. If you’re noticing frequent paw licking or scratching in these areas, allergies are often the cause.

Can Cats Have Seasonal Allergies?

Cats can absolutely experience seasonal allergies, although the signs can be a little more subtle.

Instead of obvious scratching, cats often overgroom. You may notice thinning fur, small scabs, or increased grooming around the face and neck. Because cats tend to hide discomfort, these symptoms can progress before they’re easy to spot.

When Should You Be Concerned?

Some mild itching can be normal, but if your pet seems consistently uncomfortable, it’s worth having them evaluated. Allergies tend to worsen over time if left untreated, and secondary infections are common.

You should schedule an exam if your pet:

  • Is itching frequently or intensely
  • Has red, irritated, or broken skin
  • Is losing fur or developing bald spots
  • Has recurring ear issues
  • Seems restless or uncomfortable
