What is Advocate?
Advocate is a broad-spectrum parasite treatment that not only targets fleas but also works against a range of internal and external parasites. Manufactured by Elanco, Advocate is a topical spot-on treatment that provides protection against:
- Fleas (kills adult fleas and larvae)
- Ear mites
- Sarcoptic mange
- Demodex mites
- Roundworms, hookworms, and whipworms (in dogs)
- Lungworms (in dogs and cats)
- Heartworm prevention
Advocate Product Range
Advocate is available in different formulations tailored for both dogs and cats categorized by weight ranges to ensure proper dosing. The treatment is applied monthly and absorbs into the skin, circulating through the bloodstream for systemic parasite control.
Benefits of Advocate
✔ Multi-parasite protection – Covers internal and external parasites in one application
✔ Water-resistant after 24 hours – Ideal for pets that swim or bathe frequently
✔ Easy application – Topical, mess-free spot-on treatment
✔ Kills fleas at multiple life stages – Disrupts the flea life cycle effectively
✔ Prevents heartworm – A critical advantage over some flea-only treatments
Disadvantages of Advocate
❌ Does not kill ticks – Unlike Frontline, Advocate does not target ticks
❌ Requires a prescription in some countries – Limited availability without veterinary approval
❌ Mild oily residue post-application – Some pet owners report a temporary greasy spot on the coat

What is Frontline?
Frontline, produced by Boehringer Ingelheim, is another widely used flea and tick treatment. Unlike Advocate, which focuses on multiple parasites, Frontline specializes in flea and tick control. Its key active ingredients—Fipronil and (S)-methoprene—work by killing parasites on contact, preventing infestation.
Frontline Product Range
Frontline offers several variations to suit different needs:
- Frontline Plus – Targets fleas, flea larvae, ticks, and lice
- Frontline Spray – Quick-acting treatment, ideal for heavy infestations
- Frontline Shield – Repels mosquitoes in addition to killing fleas and ticks
Frontline is also applied topically and provides 30 days of protection per dose.
Benefits of Frontline
✔ Kills fleas, ticks, and lice – A broader range of external parasite protection
✔ Works on contact – Parasites do not need to bite the pet to be affected
✔ Safe for puppies and kittens from 8 weeks old
✔ Water-resistant after 48 hours
✔ Available without a prescription – Easier to purchase than Advocate in many regions
Disadvantages of Frontline
❌ No protection against internal parasites – Does not prevent worms or heartworm
❌ Resistance concerns – Some pet owners report reduced efficacy due to resistance
❌ Slower action on fleas compared to some competitors
