Pacific Northwest Pet Owners: Spring Risks Are More Than Just Fleas
Living in the Pacific Northwest has its perks—but for pets, spring and summer also bring a very real increase in seasonal risks.
The biggest ones we watch for are:
• Fleas and ticks
• Intestinal parasites from soil, f***s, and standing water
• Blue-green algae in lakes, ponds, rivers, and slow-moving water
• Foxtails and other grass awns
• Mushrooms, yard chemicals, and outdoor toxins
One of the most serious—and often overlooked—risks in our region is blue-green algae.
In Oregon, dogs can become critically ill or even die after swimming in or drinking affected water—and many water sources are not regularly monitored. If the water looks foamy, scummy, thick like paint, pea-green, blue-green, or brownish-red, keep your pet out.
This is also the time of year when parasite pressure increases fast. Warmer temperatures, damp ground, shared outdoor spaces, and increased activity all create the perfect setup for exposure.
Prevention matters:
• Keep pets on consistent flea and tick prevention
• Stay current on deworming protocols
• Pick up waste promptly
• Do not allow dogs to drink from standing or stagnant water
• Check your dog after time outdoors (paws, ears, coat)
• Keep yards maintained and minimize high-risk exposure areas
At Knotty Creek Animal Rescue, we see the outcome of these seasonal risks every year—and most of them are preventable with the right awareness and routine care.
Spring should be enjoyed.
Just make sure you’re staying ahead of what comes with it.
