There are a number of different allergens in the world, each of which peaks at different times of the year. Here are the culprits that might be causing your dog to sneeze, scratch and/or itch uncontrollably:
Although tree pollination can begin as early as February, it can last into June. You might love the blooms, but their pollen can wreak havoc on some dogs' systems.
Early summer is a key grass pollen season in many areas. As the days get longer and the temperature gets higher, you'll probably want to spend more time outdoors with your dog. If he suffers from spring allergies, you may have good days and bad days — the temperature, the rainfall amount, and even the time of day will affect grass pollen levels, and you'll need to adjust accordingly.
Fungus spores and seeds
As summer heats up and pollination starts to wane, fungi like mold can begin to grow on fallen leaves, compost piles, grasses and grains. Like all plants, the fungi begin to spread their seeds and pollen – which can be irritants for some dogs. August is the peak season for mold spores, thanks to hot, humid weather.
Late summer to early fall is peak season for ragweed. Depending on where you live, ragweed reactions can start in August or September and continue through October and possibly November. Pollen grains are lightweight and spread easily, especially on windy days. The more wet and windy autumn is in your area, the more easily the pollen spreads, and the worse your dog’s symptoms will be.
Your dog’s over-reactions can also be caused by ingredients in his diet, and can even be genetic. Whatever the case, there are ways to help your dog through pollen season, to get the most out of summer. And when they feel better, you do too!
