Trusted Protection:
Credelio Quattro Protection Against Ticks and Fleas
In a study, lotilaner was shown to inhibit the neuromuscular function of ticks§ in just 2 hours.2
In households with existing flea infestations of varying severity, just 3 monthly doses of lotilaner reduced flea populations by 99.5-100%.
§Amblyomma americanum (lone star tick)
When it comes to killing fleas and ticks, you want it done fast
- 4 HOURS Starts killing fleas in just 4 hours
- 8 HOURS Kills >99% of fleas within just 8 hours of administration3
- 12 HOURS Lotilaner kills 100% of fleas within 12 hours and remains effective for an entire month3



Half-Life
Lotilaner reaches peak absorption in only 2 hours and maintains high, sustained blood levels for the entire month.8

Easy to Pick Up, Hard to Diagnose
Tapeworm infections are common, but some can be easy to miss.
Dipylidium caninum can be diagnosed by their shedding of large, visible proglottids. Adult tapeworms range from 15-70 cm.9

Echinococcus are difficult to diagnose due to their small size and low number of body segments. E. granulosus grow to just 2-7 mm.10
A Disease Risk
Tapeworms don't just threaten dogs: they can be passed to humans. CAPC recommends monthly deworming of dogs with praziquantel in areas where E. granulosus tapeworms are endemic.10
A single monthly dose of Credelio Quattro has been shown to be 100% efficacious against tapeworms# in dogs with its industry-established dose of praziquantel (2.28mg/lb).
#Echinococcus granulosus, Dipylidium canium, and Taenia pisiformis
