Victoria,
I feel for you! A few of us here have had our fair share of stubborn dog owners who just refuse to get the facts and do what is truly good for their companion…
That Ol’ Roy is crap, you obviously know… I guess, if you can, try to get a small bag of Walmart’s Pure Balance/Pure Balance Grain Free (two of the more decent foods sold at Walmart), and maybe entice the family to try and add some to Ol’ Roy, see how their dogs like it. When I added some of the food I feed my dog to the food of the dog of the family for whom I babysit, she did not want to touch her Kibbles ‘N’ Bits anymore at all! Lol, she knew the good stuff! Maybe this will help them – plus, Pure Balance is ALSO sold at Walmart, where Ol’ Roy is.
Another thing you could do, is just add some good canned food as a topper to their meals, or a raw/lightly cooked egg here and there, some canned sardines, coconut oil if you have/can afford it, and some plain yoghurt and canned pumpkin (plain, not the pie-filling stuff). That’s what I do even with better-quality kibble and I believe it helps. If you can throw some raw/lightly cooked meat in there, or raw meaty bones here and there, it should help improve their diet a TAD, but really do try to get them off of Ol’ Roy…
Good luck, and know that many of us have been there too!
