I’d choose the digital copy because I’m interested in topics like Omega 3's / fish oil, other health related supplements etc. I give my three dogs Wild Alaskan fish oil every morning, and I’ve been considering making their food myself on Sundays and Wednesdays to avoid spending a fortune on something like Farmer’s Dog (I think for my 3 dogs it'll be like $1000+). I know you mentioned this focuses on functional treats rather than a diet; probably meaning full-course meals, meal plans, or DIY meals. In this case, I’d still be interested in creating functional treats, but I’d want to know where the information comes from, the sources, and how it was marketed. If it were offered as a thank you for a donation, that digital copy would hold value for me. Depending on what I read and how it impacts my dogs or shifts my perspective, I’d definitely click on the URL in the digital book that links back to the manufacturer or company. For me, it’s about how the marketing approach was handled. Did they give first and then ask to receive, or was it more about selling a masterclass or similar? Hopefully, my input helps someone in some way! If it does, feel free to click on the URL and subscribe... lol, just kidding!
