I'm very happy with my bespoke supplement from Hackup, which is mixed specifically for Alf. I had a conversation with Alex yesterday about mud fever prevention, and my bespoke has now been tweaked to add a vitamin and mineral premix and some pre/probiotics, so that he gets everything he needs, both for his dodgy legs, and his overall health and wellbeing, in one pot. I love being able to have input in what I give him.
