2 Types of Parasites in Dogs
External Parasites
External parasites live on your dog’s skin and fur, causing intense itching, skin irritation, and allergic reactions. These pests can transmit serious diseases like Lyme disease and Rocky Mountain spotted fever. Beyond the immediate discomfort they cause, external parasites can lead to secondary skin infections from excessive scratching. Some external parasites can also infest your home environment, making treatment more challenging and expensive.
4 Kinds of External Parasites in Dogs
- Fleas – These tiny jumping insects feed on your dog’s blood and reproduce rapidly. A single flea can lay up to 50 eggs per day, quickly creating a severe infestation in your home.
- Ticks – These spider-like parasites attach firmly to your dog’s skin and can transmit multiple diseases with a single bite. They’re most active in wooded or grassy areas but can be found year-round in many climates.
- Mites – Microscopic parasites that burrow into the skin causing mange, intense itching, and hair loss. Different species of mites cause various conditions, from ear mites to demodectic mange.
- Lice – These species-specific parasites attach their eggs to hair shafts and cause severe itching. Dog lice cannot transfer to humans but can spread rapidly between dogs in close contact.
Internal Parasites
Internal parasites live inside your dog’s body, primarily in the digestive system, heart, and lungs. These parasites steal vital nutrients from your pet, leading to weight loss, anemia, and digestive problems. Many internal parasites are zoonotic, meaning they can be transmitted to humans, especially children. Without proper treatment, some internal parasites like heartworms can be fatal to your dog.
6 Kinds of Internal Parasites
- Heartworms – These worms live in the heart and pulmonary arteries, causing severe cardiovascular damage. Transmitted by mosquitoes, heartworm disease is much easier to prevent than treat.
- Roundworms – The most common intestinal parasite in dogs, especially puppies. These spaghetti-like worms can grow up to seven inches long and cause pot-bellied appearance and poor growth.
- Hookworms – These blood-sucking parasites attach to the intestinal wall and can cause severe anemia. They can also penetrate human skin, causing a condition called cutaneous larva migrans.
- Tapeworms – Transmitted through flea ingestion or eating infected prey, these segmented worms can grow several feet long. You might notice rice-like segments in your dog’s stool or around their rear end.
- Whipworms – These thread-like parasites live in the large intestine causing chronic diarrhea and weight loss. Their eggs can survive in the environment for years, making reinfection common.
- Giardia – A microscopic protozoan parasite that causes severe diarrhea and dehydration. It’s commonly contracted from contaminated water sources and can spread to humans.
4 Professional Parasite Preventatives
Oral Medications
Oral parasite preventatives come in flavored chewable tablets or pills that your dog takes monthly. These medications work systemically, circulating through your dog’s bloodstream to kill parasites that bite or infest your pet. Many oral preventatives protect against multiple parasites including fleas, ticks, heartworms, and intestinal worms. The convenience of monthly dosing and broad-spectrum protection makes oral medications a popular choice. Your veterinarian can recommend the best oral preventative based on your dog’s size, age, and lifestyle factors.
Topical Treatments
Topical preventatives are liquid medications applied directly to your dog’s skin, usually between the shoulder blades. These treatments spread across the skin’s surface through natural oils, providing month-long protection against external parasites. Some topical medications also absorb into the bloodstream to protect against internal parasites. They’re waterproof once dry and ideal for dogs who are difficult to pill. Application is simple, but you’ll need to prevent your dog from licking the area until the medication dries completely.
Injectable Preventatives
Injectable parasite preventatives provide long-lasting protection with a single veterinary visit. These injections can protect against heartworms for six to twelve months, eliminating the need for monthly dosing. Some newer injectable formulations also protect against fleas and ticks for up to twelve weeks. This option is perfect for pet owners who struggle with monthly medication compliance. Your veterinarian administers the injection during a regular office visit, ensuring proper dosage and monitoring for any reactions.
Combination Products
Modern combination preventatives protect against multiple parasites with a single medication. These products might combine flea, tick, heartworm, and intestinal worm protection in one monthly dose. Using combination products simplifies your pet’s preventative care routine and often costs less than purchasing separate medications. Your veterinarian can help you choose a combination product that addresses all the parasites common in your geographic area. These veterinary-exclusive products are more effective and safer than over-the-counter alternatives.
8 Tips for Preventing Parasites at Home
- Keep your yard well-maintained by regularly mowing the grass and removing leaf litter where parasites thrive. Trim bushes and trees to reduce shaded, moist areas that attract fleas and ticks.
- Clean up pet waste immediately from your yard since many intestinal parasite eggs are shed in feces. This simple step prevents reinfection and protects neighborhood pets too.
- Vacuum your home frequently, especially in areas where your dog spends time. Don’t forget to vacuum under furniture and wash your dog’s bedding weekly in hot water to kill any flea eggs or larvae.
- Check your dog daily for ticks, particularly after walks in wooded or grassy areas. Run your hands through their fur, paying special attention to ears, neck, and between toes where ticks like to hide.
- Avoid letting your dog drink from puddles or standing water which can harbor Giardia and other waterborne parasites. Always bring fresh water on walks and hikes.
- Schedule regular veterinary check-ups including annual fecal testing to catch any parasites early. Even dogs on preventatives should be tested yearly to ensure the medications are working effectively.
- Keep your dog away from wildlife and their droppings since wild animals often carry parasites that can infect pets. This includes avoiding areas heavily populated by deer, which carry ticks.
- Maintain year-round prevention rather than stopping during winter months. Many parasites can survive indoors or in protected outdoor areas even during cold weather.
Conclusion
Year-round parasite prevention is essential for protecting your dog’s health and your family’s wellbeing. By combining professional veterinary care with consistent at-home prevention strategies, you can keep harmful parasites at bay.
