The cause of your dog developing hay fever is the allergic reaction to pollen. These pollens leading to hay fever are from grass, trees, weeds or any other plants. The most common pollens behind your dog developing hay fever are oats, corn and ragweed.

The pollens are present in the air and when your dog inhales the air or comes in contact with them they suffer from hay fever. The contact of pollen, the immune system of the dog reacts negatively and produces the chemical.

Due to the reaction between pollen and the dog’s immune system, inflammation, itching and runny nose occur in the dog. The type of pollen depends upon the region and weather. Some dogs might be allergic to some kind of pollen while others may not be.

As mentioned by Melissa Boldan, DVM in petmd, "When dogs inhale or consume pollen by licking their feet or fur, they can have various allergic reactions. The tiny pollen particle is seen as a foreign substance by the dog’s immune system, which mounts an attack in response. The main cell type the immune system mobilizes during the attack is called a mast cell. Mast cells are responsible for the production of histamine, among other biochemicals. When histamine is released, it causes itching, redness, and swelling."
