The Problems Parasites Cause for Pets
Parasites can cause trouble before you ever see a flea, find a tick, or notice a change in your pet’s behavior. Some parasites irritate the skin, while others can spread disease, affect internal organs, or create health risks that are harder to detect without veterinary testing.
Common parasite-related concerns include:
-
Flea allergy dermatitis and intense itching
-
Tapeworms from flea exposure
-
Tick-borne diseases, including Lyme disease, ehrlichiosis, anaplasmosis, and Rocky Mountain spotted fever
-
Heartworm disease from mosquito bites
-
Intestinal parasites such as roundworms and hookworms
-
Anemia in young, small, or heavily infested pets
-
Skin infections from scratching, licking, and chewing
-
Household flea infestations that can be difficult to eliminate
When Should My Pet Use Parasite Prevention?
Most dogs and cats benefit from parasite prevention year-round. Fleas can survive indoors, ticks may remain active during mild weather, and mosquitoes can appear whenever conditions allow.
Puppies and kittens should begin prevention once they reach the appropriate age and weight for a safe product. Adult pets need ongoing protection to stay covered, while senior pets may need updated recommendations based on their health, medications, or lifestyle.
If your pet hikes, travels, boards, visits dog parks, lives with other animals, or spends time outdoors, consistent prevention becomes even more important. Even indoor pets can be exposed when parasites enter the home on shoes, clothing, other pets, or household items.
