Yes, as a training tool — but with a critical caveat. The strong smell of freeze-dried liver makes it effective for picky eaters during training sessions. As a food topper to encourage kibble acceptance, crumble sprinkled on the meal can help. The risk is accidentally training the dog to hold out for liver by using it as a reward for refusing other food.

Why picky eaters respond to liver
Dogs refuse food for different reasons: low palatability of the food itself, learned fussiness from being hand-fed or given too many treat options, stress or anxiety, or occasionally medical issues. Freeze-dried liver is among the highest-palatability foods available to dogs — the concentrated umami smell triggers appetite in most dogs, even those who are otherwise indifferent to food.
This is useful for training because it provides a reliable motivator for a dog that does not respond to lower-value treats. For a dog that ignores kibble pieces, biscuits, or soft training treats, liver is often the thing that finally gets a response. This does not fix the underlying pickiness — it is a tool for getting behavior during training, not a long-term dietary solution.
Using liver as a food topper
Crumbling a small amount of freeze-dried liver over kibble adds strong liver scent to the meal, which can improve acceptance in picky eaters. This works by contaminating the smell of the whole bowl — the kibble now smells like liver to the dog. Many owners report that their picky dogs eat the kibble they were previously refusing once the liver scent is present.
The amount needed is small — a pinch of crumble per cup of kibble. The goal is scent, not flavor. You are not replacing the kibble with liver; you are making the kibble smell more appealing. This keeps the protein, fat, and micronutrient balance of the diet intact while improving acceptance.
The holdout risk: how to avoid it
The risk with any high-value treat used around mealtime is training the dog to refuse the regular meal in order to get the better food. This is learned behavior, and it is surprisingly easy to establish: dog refuses kibble, owner adds liver topper, dog eats — the dog has now learned that refusing kibble results in liver appearing. Over time, the dog becomes reliably fussy in order to reliably get the upgrade.
Prevention: use liver topper consistently from the start rather than as a response to refusal. If the topper is always there, refusing kibble does not make anything change. The meal consistently smells like liver, and the dog learns this is just how the meal comes. Only add the topper as an emergency measure if you are very careful to return to the no-topper baseline within a few days.
Better strategies for true picky eaters
Food-motivated training with high-value treats (including liver) to build a positive relationship with eating; meal-feeding rather than free-feeding (dogs who graze tend to be pickier because food is always available); removing the bowl after 15 minutes if untouched rather than adding incentives (hunger is a powerful appetite stimulant); and addressing any anxiety or stress factors that might be suppressing appetite.
Liver treats can support all of these strategies without becoming the problem themselves, as long as they are used as motivators during training and not as mealtime bribes.
When pickiness signals something medical
A dog that was previously a reliable eater but has become suddenly picky may have a medical cause: dental pain making eating uncomfortable, nausea from medication or a GI issue, reduced olfactory function (common in older dogs), or a metabolic issue affecting appetite. If pickiness is sudden rather than long-standing, or if accompanied by weight loss, lethargy, or other changes, a vet visit is appropriate before trying behavioral interventions.
