Deworming Dogs: Why and How to Do It – Complete Guide
Good health for dogs is not just about nutritious food and timely vaccinations – deworming is equally essential. Worms and parasites can silently damage a dog’s health, affecting growth, immunity, and even lifespan. As explained by Vɪsʜɴᴜ Dᴜᴛᴛ Tʀɪᴘᴀᴛʜɪ | Pᴇᴛ Exᴘᴇʀᴛ, regular deworming is the cornerstone of preventive healthcare for dogs.
Some of these parasites are zoonotic, meaning they can also infect humans. By keeping your dog dewormed, you are protecting both your furry friend and your family.
Why is Deworming Important?
Dogs can easily get exposed to intestinal worms and parasites through:
Contaminated soil, grass, or water
Fleas, ticks, or mosquito bites
Eating raw or undercooked meat
Contact with infected animals
Unchecked worm infestations can lead to weight loss, dull coat, diarrhea, poor growth, anemia, and in severe cases, organ damage.
Common Parasites in Dogs

Effect on Dog
Transmission
Roundworm (Toxocara canis)
Abdominal swelling, vomiting, poor growth
Mother to puppy (placenta/milk), contaminated soil
Hookworm (Ancylostoma caninum)
Blood loss, anemia
Soil, direct contact, ingestion
Whipworm (Trichuris vulpis)
Chronic diarrhea, weakness
Soil contamination
Tapeworm (Dipylidium / Taenia)
Weight loss, dull coat
Fleas, raw meat, prey animals
Heartworm (Dirofilaria immitis)

Deworming Schedule – Puppies to Adults
Age / Category
Deworming Schedule
Notes
Puppies (0–6 months)
Start at 2 weeks → every 2 weeks until 12 weeks → then monthly until 6 months
Puppies have low immunity; high maternal transmission risk
Adult Dogs
Every 3 months (house dogs) / Every 1–2 months (outdoor, show, breeding dogs)
Lifestyle-based frequency
Toy / Indoor Dogs
Every 3 months
Indoor contamination and self-grooming risk
Raw-fed / Hunting Dogs
Monthly
High exposure to parasites and prey animals
Raw-Fed Dogs & Hunting/Field Dogs
Raw-fed dogs and those involved in fieldwork or hunting are at higher risk of parasitic infections. Monthly broad-spectrum deworming, including Praziquantel for tapeworms, is recommended.
Indoor & Toy Breeds – Do Not Skip Deworming!
Many pet parents assume indoor dogs do not need deworming. This is incorrect. Indoor pets can still ingest parasite eggs by:
Licking contaminated paws or fur
Contact with dust, shoes, or infected pets
Close contact with humans (some parasites are zoonotic)
Indoor dogs should be dewormed every 3 months for optimal health.
Why Rotate Deworming Medications?
Using the same drug repeatedly may lead to parasite resistance. Rotating between active ingredients ensures effective parasite control.

Health & Hygiene Tips for Dog Owners
Always administer weight-based doses.
Combine deworming with regular flea, tick, and heartworm control.
Clean and disinfect your dog’s bedding, bowls, and living areas regularly.
Wash your hands after handling pets or cleaning up after them.
Deworm nursing mothers along with puppies to prevent re-infestation.
Regularly check your dog’s stool for abnormalities and consult a vet if symptoms persist.
