狗和猫的肠道蠕虫：完整指南
蛔虫、钩虫、绦虫和鞭虫是宠物常见的肠道寄生虫。了解它们如何传播、需要注意的症状以及预防策略。
肠道蠕虫是影响全世界（包括澳门）猫狗最常见的健康问题之一。四种主要类型——蛔虫、钩虫、绦虫和鞭虫——可引起腹泻、体重减轻、贫血，严重时甚至导致死亡（尤其是小狗和小猫）。许多受感染的宠物没有任何症状，因此定期驱虫和粪便检测对每只宠物都至关重要。
要点
- Roundworms are the most common — puppies are often born with them (transferred from mother)
- Hookworms feed on blood and can cause severe anemia, especially in puppies
- Tapeworms are transmitted by fleas — visible as rice-like segments near the pet's rear
- Some intestinal worms (roundworms, hookworms) can infect humans — especially children
- Regular deworming every 3 months is recommended for most pets
- Fecal testing 1-2 times per year detects infections even without symptoms
Types of Intestinal Worms
Roundworms (Toxocara): most common, 10-15cm long, spaghetti-like appearance. Puppies are often born infected. Symptoms: pot-bellied appearance, vomiting worms, diarrhea. Hookworms: tiny, attach to intestinal wall and feed on blood. Cause severe anemia in puppies. Tapeworms (Dipylidium): flat, segmented, transmitted by fleas. Segments visible near anus or in stool — look like rice grains. Whipworms: live in the large intestine, cause chronic diarrhea and weight loss.
How Pets Get Infected
Roundworms: from mother's milk (puppies/kittens), contaminated soil, or eating infected prey. Hookworms: through skin (larvae penetrate paw pads), mother's milk, or ingestion. Tapeworms: by swallowing infected fleas during grooming. Whipworms: from contaminated soil. Outdoor pets, hunting animals, and pets in multi-animal households are at higher risk.
Treatment
Deworming medications (anthelmintics) kill intestinal worms. Common medications: fenbendazole (Panacur), pyrantel pamoate, praziquantel (for tapeworms), and milbemycin. Treatment usually requires 1-3 doses over several weeks. For tapeworms, flea control is essential — without eliminating fleas, reinfection occurs. Follow-up fecal testing confirms the worms are cleared.
Prevention Schedule
Puppies/kittens: deworm at 2, 4, 6, and 8 weeks of age, then monthly until 6 months. Adult dogs/cats: deworm every 3 months (quarterly). Hunting/outdoor pets: monthly deworming recommended. Yearly fecal testing catches infections early. Flea prevention is essential for tapeworm control. Pick up pet waste promptly to reduce environmental contamination.
