Assessed clinical scopeDog · Full labelled species-specific scope for treatment or prevention of susceptible flea, mite, nematode and heartworm targets · On the skin
Care settingMonthly or indication-specific single-pipette spot-on treatment after exact species, weight, parasite and heartworm-risk assessment
vetman score 8.6/10 Very good
Evidence confidence: High Georgia: Yes, veterinary · № 274-11 · Verified on 15 Oct 2026

A mature, strongly supported broad endectocide for dogs and cats with convenient monthly topical dosing and well-defined species-specific label roles.

Regulatory and scientific credibility9.0/10

Every exact presentation is registered in Georgia and the reference product has mature current EU/UK and FDA authorisations.

Clinical efficacy9.0/10

Large randomized masked field programmes support high efficacy for fleas, heartworm prevention and labelled mite targets across dogs and cats, with extensive long-term clinical use.

Safety and tolerability8.0/10

The safety margin is well characterised and generally favourable, but species/weight mismatch, very young age, debilitated or underweight cats, wet or damaged skin, ingestion and heavily microfilaraemic dogs require specific precautions.

Clinical practicality8.5/10

A premeasured monthly pipette is simple and avoids oral administration, but correct skin exposure, full-pipette delivery, drying time and prevention of licking are necessary for reliable use.

Full-course cost-effectiveness-

Price was not assessed and is excluded from the overall score.

Important safety and use flags

  • Use only the exact species and weight-band pipette; do not split a pipette or substitute dog and cat presentations solely by milligram strength.
  • Do not use below six weeks of age or on wet, broken or otherwise unsuitable application skin; observe the locally applicable exact label.
  • Apply the complete pipette directly to exposed skin, prevent licking and close contact until dry, and keep away from flame or ignition sources during drying.
  • Confirm the target parasite and repeat interval; investigate apparent failure for application technique, bathing, reinfection and resistance rather than empirically increasing dose.
  • For heartworm prevention, test according to local epidemiology and the exact label; heavily microfilaraemic dogs require veterinary assessment and monitoring for acute reactions.

Stronghold

240 mg, selamectin 240 mg (120 mg/ml), spot-on solution for dogs 20.1-40 kg
Assessed clinical scopeDog · Full labelled species-specific scope for treatment or prevention of susceptible flea, mite, nematode and heartworm targets · On the skin
Care settingMonthly or indication-specific single-pipette spot-on treatment after exact species, weight, parasite and heartworm-risk assessment
vetman score 8.6/10 Very good
Evidence confidence: High Georgia: Yes, veterinary · № 301-11 · Verified on 15 Oct 2026

A mature, strongly supported broad endectocide for dogs and cats with convenient monthly topical dosing and well-defined species-specific label roles.

Regulatory and scientific credibility9.0/10

Every exact presentation is registered in Georgia and the reference product has mature current EU/UK and FDA authorisations.

Clinical efficacy9.0/10

Large randomized masked field programmes support high efficacy for fleas, heartworm prevention and labelled mite targets across dogs and cats, with extensive long-term clinical use.

Safety and tolerability8.0/10

The safety margin is well characterised and generally favourable, but species/weight mismatch, very young age, debilitated or underweight cats, wet or damaged skin, ingestion and heavily microfilaraemic dogs require specific precautions.

Clinical practicality8.5/10

A premeasured monthly pipette is simple and avoids oral administration, but correct skin exposure, full-pipette delivery, drying time and prevention of licking are necessary for reliable use.

Full-course cost-effectiveness-

Price was not assessed and is excluded from the overall score.

Important safety and use flags

  • Use only the exact species and weight-band pipette; do not split a pipette or substitute dog and cat presentations solely by milligram strength.
  • Do not use below six weeks of age or on wet, broken or otherwise unsuitable application skin; observe the locally applicable exact label.
  • Apply the complete pipette directly to exposed skin, prevent licking and close contact until dry, and keep away from flame or ignition sources during drying.
  • Confirm the target parasite and repeat interval; investigate apparent failure for application technique, bathing, reinfection and resistance rather than empirically increasing dose.
  • For heartworm prevention, test according to local epidemiology and the exact label; heavily microfilaraemic dogs require veterinary assessment and monitoring for acute reactions.
