Top 8 Intestinal Dewormers & Anthelmintics for Small Animals in Canada (2025): Vet-Recommended Options, Dosing Tips and Resistance Guidance

Milbemax is recognized for its cat-specific tablet formulations that combine reliable intestinal parasite coverage with smaller, feline-friendly dosing increments, making it a preferred choice for veterinary-prescribed feline deworming. Relative to Drontal Plus (dog-focused) and Profender (a premium feline option), Milbemax strikes a balance between targeted feline efficacy and affordability, often making it a practical clinic-stocked choice for routine cat parasite control.

Panacur is a best-in-class fenbendazole oral suspension known for a broad-spectrum activity and an excellent safety profile for small animals, making it a go-to for multi-day regimens against common intestinal nematodes. Compared with single-dose pyrantel products on this list, Panacur’s technical advantage is its wider parasite coverage and well-established clinical history, though it often requires a longer dosing course and sits in the mid-range price tier compared with cheaper single-dose alternatives.

Droncit Injectable (praziquantel) is the go-to injectable cestocide for treating intestinal tapeworms in small animals; its focused, high-efficacy action against tapeworms complements nematocide or benzimidazole therapies. Unlike the macrocyclic lactones (Ivomec, Dectomax, Noromectin) and fenbendazole (Panacur), Droncit fills the cestode niche and is often used in combination protocols—its targeted value justifies its role despite not addressing nematode or protozoal burdens on its own.

Interceptor Plus is a market leader because it pairs intestinal parasite control with proven monthly heartworm prevention, offering milbemycin oxime plus praziquantel in a palatable chew that simplifies comprehensive parasite protection. Technically and financially it carries a premium versus straight intestinal dewormers, but it delivers added value for owners seeking consolidated prevention against both intestinal worms and heartworm with one product.

Droncit is a long‑established praziquantel tablet frequently used as a dependable, single‑dose tapeworm dewormer with a straightforward dosing profile that keeps veterinary time and owner confusion low. Its technical strength is the focused antiparasitic action against tapeworms, making it comparable to Cestex on cost but often favored for its well‑documented efficacy and historical clinical use. Compared with combination drugs like Milbemax or Drontal Plus, Droncit is a simpler, typically less expensive option when tapeworms are the sole target.

Panacur (fenbendazole) granules are a flexible, veterinary‑proven option for roundworm and hookworm control that can be dosed over multiple days and adjusted precisely for small or young animals, and are widely used where tailored regimens are preferred. While it typically requires several days of treatment unlike single‑dose chewables such as Drontal or Milbemax, Panacur's generic availability and ease of dose titration give it a financial and technical advantage for long or targeted treatment courses.

Bayer's Drontal Plus holds a market‑leader position as a broad‑spectrum, cost‑efficient value pack formulated to treat tapeworms, roundworms and hookworms in small animals. Compared with the single‑agent or short‑course products in this list, its one‑dose spectrum and lower per‑dose cost make it attractive for owners building deworming kits or initiating prevention protocols that require immediate broad coverage.
