natural ingredients or natural flavor = some kind of chemicals, wheat flour, wheat gluten, glycerin, gelatin, oat fiber, water, lecithin, natural poultry flavor... A few years back it was published: Greenies, become lodged in a dog's esophagus or intestine and then some veterinarians say they don't break down. Also, I sure wouldnāt give anything that look green that has absolutely no mentioned anywhere where the colour green comes from. Just tell your neighbour heās allergic to wheat as main ingredient is wheat.
What you can do so Jackson likes his neighbour, at Costco they sell a bag of dry liver. Blue bag. Itās only that one ingredient. Here in Canada itās like $10 but in the US is probably $8. I would buy her a bag so when she sees Jackson she can give him that treat instead. Also it might help her lose the greenies n buy something healthier for her dogs. Just a thought.
