I think the best people to “change” are the non-stubborn ones… cause you have clearly hinted, probably even more than just lightly, that there’s better out there than Beneful, but he’s just not budging. Same with my Science Diet fan of a roommate… he is so CERTAIN that it’s the best food ever because his vet is ok with it and because his brother fed his rottie it for 14 years, so yeah… My success stories are all of open-minded people who want the best for their dogs and don’t get defensive when talked to about dog food. Also, taking them shopping and showing them couponing tricks of the trade and where to find awesome sales has helped a ton! But, with stubborn people like the GSD owner you just can’t do that… unless one day you lose it and yell in his face about how he’s feeding his babies trash…
