Evidence has levels. We show them.

Learn how PET157 separates direct canine outcomes from safety data, preclinical studies and human investigations.

Evidence informed. Transparently graded.

Every source keeps its proper weight.

A promising mechanism is not the same as a proven outcome in dogs.

A
Direct canine evidenceResults measured in the target species.
B
Canine safety and PKUseful evidence answering different questions.
C
Preclinical researchContext that cannot establish a canine outcome.
I
Insufficient evidenceNot enough research for a conclusion.

How to read a PET157 page

Direct canine clinical evidence carries more weight for a dog-health decision than a mechanism or a result in another species. Safety and pharmacokinetic evidence can answer different questions from efficacy research.

Approval is separate again

Research activity does not mean a compound is approved for veterinary use. Availability can also differ by country and by the professional pathway involved.
