The speaker’s main thesis is that most of these “sensitive stomach” and GI-style diets are much more alike than marketing suggests, and that the real differentiator is not the headline ingredient panel but the microbiome strategy behind the formula. He says the new Purina Pro Plan AdvanEDGE Digestive Support is very close nutritionally to Pro Plan Sensitive Stomach and Skin, with the likely meaningful difference being the inclusion of probiotics in the newer diet. He also argues that Hill’s Science Diet Perfect Digestion is the most distinct of the group because it is built around prebiotics and microbiome support rather than live probiotics. He walks through protein, fat, carbohydrate, calcium, phosphorus, sodium, vitamin E, calories per cup, and cost per pound for the Purina diets and Hill’s formulas. …
Tactically, the immediate setup is a choice between nearly duplicate GI diets, with the extra cost of AdvanEDGE only making sense if a dog specifically benefits from probiotics. The fastest way to de-risk the decision is a short trial and a quick return if there is no visible improvement.
Over the next few weeks, the likely outcome is that most pets will cluster into a few clear responders, while the majority may do just as well on the cheaper near-equivalent. Hill’s Perfect Digestion looks like the cleaner base-case option when weight and microbiome support matter together.
Structurally, the pet food category is moving toward microbiome-led formulation rather than simple protein-source storytelling. The durable winner in this regime is likely to be the brand that can prove functional benefit without relying on premium-label inflation.
The new Pro Plan AdvanEDGE Digestive Support is very similar to Pro Plan Sensitive Stomach and Skin nutritionally.
He compares protein, fat, carbs, minerals, vitamin E, and calories and says there is no big difference.
The main difference in the new Purina digestive formula is the addition of probiotics.
He explicitly says that is the added value justifying the premium.
He prefers prebiotics over probiotics because prebiotics feed the pet's own microbiome more naturally.
