As spring transitions into early summer in Whatcom County, veterinarians are reminding pet owners to stay alert for ticks and intestinal parasites that become more active this time of year. Warmer temperatures, increased rainfall and more time spent outdoors create ideal conditions for parasites that can affect both pets and people.
Ticks are especially common in late spring and early summer, thriving in tall grass, wooded areas and along popular walking trails. Dogs that hike, explore backyards or frequent parks are at higher risk of exposure. Cats that spend time outdoors can also encounter ticks, even in residential neighborhoods.
Ticks can transmit serious diseases, including Lyme disease and anaplasmosis, which may cause symptoms such as lethargy, fever, joint pain and loss of appetite. In some cases, symptoms may not appear until weeks after a bite, making prevention and routine checks critical.
Veterinarians at Whatcom Veterinary Hospital recommend using veterinarian-approved tick preventives and performing daily tick checks, especially after outdoor activities. Early removal reduces the chance of disease transmission.
Intestinal parasites also become more prevalent during this season. Roundworms, hookworms, whipworms and Giardia are commonly diagnosed in dogs and cats throughout the Pacific Northwest. Pets can become infected through contaminated soil, standing water, wildlife droppings or contact with other animals.
Puppies and kittens are particularly vulnerable, but adult pets are not immune. Some intestinal parasites can be passed from mother to offspring or picked up during routine outdoor play. Infected pets may show symptoms such as diarrhea, vomiting, weight loss or a dull coat, though some animals show no outward signs at all.
Because some intestinal parasites are zoonotic — meaning they can spread to humans — regular testing and prevention are important for household health. Veterinarians typically recommend routine fecal exams as part of annual or semiannual wellness visits, especially during peak parasite seasons.
Monthly parasite preventives often protect against multiple threats, including intestinal worms and, in some cases, ticks. Pet owners are encouraged to discuss lifestyle factors, such as outdoor access and travel, with their veterinarian to choose the most appropriate protection.
Spring is also a common time for pets to visit dog parks, boarding facilities and grooming salons, which can increase exposure risks. Keeping pets on consistent prevention and up to date on wellness care helps reduce the chance of infection.
Veterinary professionals advise against waiting for symptoms to appear before taking action. Preventive care remains the most effective way to protect pets during peak parasite months.
As pets spend more time outdoors in the coming weeks, awareness and early prevention can help ensure a healthy, active season for animals and their families across Whatcom County.
