What To Look For In a Dog Dewormer Product?

A broad-spectrum dewormer product can treat or safe-gaurd most worms in puppies, small dogs, and large dogs. However, there are specific types of dog dewormers that target specific parasites.

Common Types of Dog Worms

  • Roundworms (Toxocara spp. and Toxascaris leonina): Symptoms include diarrhea, vomiting, bloated abdomen, and visible worms. Transmission is through mother's milk, contaminated soil, or feces.
  • Hookworms (Ancylostoma spp. and Uncinaria spp.): Symptoms include blood loss, anemia, and skin irritation. Transmission is through ingestion or skin contact.
  • Whipworms (Trichuris vulpis): Symptoms include chronic diarrhea and weight loss. Transmission is through contaminated soil or feces.
  • Tapeworms (Dipylidium caninum and Taenia spp.): Symptoms include digestive disturbances and visible segments in feces. Transmission is through fleas or infected rodents.
  • Giardia (Giardia spp.): Symptoms include diarrhea, vomiting, and abdominal discomfort. Transmission is through contaminated water or feces.
  • Coccidia (Coccidia spp.): Symptoms include diarrhea and dehydration. Transmission is through contaminated feces or soil.
  • Lungworms (Angiostrongylus vasorum and others): Symptoms affect the respiratory system. Transmission is through infected snails or slugs.

How To Identify the Type of Worms

Your vet should be able to confirm and tell you which type of worm is found through a stool sample test.  If your vet says a broad-spectrum dewormer will work, then you can choose from one of the brands above.

Active Ingredients For Different Dewormers For Dogs

  • Pyrantel Pamoate: This dewormer targets roundworms and hookworms by paralyzing them. Once paralyzed, can excrete them naturally through stool and urine. It's ideal for puppies.
  • Fenbendazole: Acts as a broad-spectrum dewormer, killing tapeworms, roundworms, hookworms, and certain Giardia by disrupting their energy use. It's used in multi-day treatments.
  • Praziquantel: Targets tapeworms by damaging their skin, leading to their digestion by the dog. It's commonly used with other dewormers for broad-spectrum treatment.
  • Milbemycin Oxime: This kills heartworms, hookworms, roundworms, and whipworms by blocking their nerve transmission. It's used for both treatment and heartworm prevention, known for its broad-spectrum effectiveness.
  • Ivermectin: Used against heartworms, mites, and lice, paralyzing and killing parasites by messing with the parasite's nerves and muscles. Some dog breeds are sensitive to it and can lead to some unwanted side effects.

Signs and Symptoms Of Parasites Or Tapeworms

Keep an eye out for digestive distress, weight loss, lethargy, visible worms, itching, and changes in appetite.

Preventing Worms In Dogs

Regular veterinary checkups, fecal exams, hygiene and cleanup, regular deworming, flea and tick control, avoiding raw meat, and limiting contact with infected animals are key to prevention.
