In accordance with the FTC's 16 CFR Part 255 ("Guides Concerning the Use of Endorsements and Testimonials in Advertising"), here is exactly how this site makes money.
The plain-language version
Best Collagen for Dogs is reader-supported. Some links on this site are affiliate links — including links to Colapaw, Amazon, and other retailers. If you click one and make a purchase, we may earn a commission. This never costs you anything extra.
What this means for our reviews
Affiliate commissions fund our research time. They do not buy rankings: no brand can pay for a higher position, and we recommend products we would (and do) give to our own dogs. Where we earn a commission on a product we rank #1, that's because it earned the spot on our criteria — not the other way around. You can read exactly how we score products in the "How We Rank" section of our main guide.
Amazon Associates
As an Amazon Associate, we earn from qualifying purchases.
Sponsored links
All affiliate links on this site carry the rel="sponsored" attribute in line with Google's guidelines.
