Yes, Stewart freeze-dried beef liver has a noticeable meaty smell. It's not overpowering in a closed bag, but once you open it and handle the treats, the scent transfers to hands and persists for a few minutes after washing. It's the smell of raw liver — concentrated. This is intentional: the aroma is a primary reason dogs respond so strongly to these as training rewards.

How strong the smell actually is
Opening a sealed 16oz pouch of Stewart liver for the first time gives you a solid hit of concentrated beef liver — think raw liver from a butcher's counter, but dried and amplified because the moisture that normally carries the smell around is gone and the volatile aroma compounds are more concentrated per square inch of surface area.
Once the bag is sealed again, the smell does not escape into a room. A closed pouch stored in a cabinet does not make the cabinet smell. Opened and left out, the odor dissipates in a few minutes. The issue is handling: holding pieces deposits the smell on fingertips, and washing with regular hand soap gets most of it — two washes with warm water and soap clears it completely in most people.
Why the odor is a feature, not a defect
The smell is the training signal. Dogs have olfactory receptor density roughly 40 times higher than humans. A treat that smells mildly to you smells overwhelming to a dog — which is why liver works as a high-value reward in a way that biscuits do not. The scent creates anticipation and drives motivation, particularly for dogs that are picky about food or in high-distraction environments where they need extra incentive.
For recall training, scent-strong treats like liver are specifically recommended by many trainers because the dog can smell them in your pocket from a distance. That anticipation affects behavior before the treat is even visible.
Handling tips if you find it unpleasant
Pre-portion into a small silicone treat bag or repurposed zipper bag before leaving the house. This keeps the full pouch sealed and reduces how often you need to reach in directly. Some handlers use silicone treat bags with a snap closure — the treats are contained, and the bag can be rinsed after a session.
Nitrile gloves are the cleanest option for people with strong smell sensitivity, though most handlers find that excessive for training. Another approach: break the pieces in advance and transfer them to a small container with a lid. The lid keeps the smell contained between uses.
Does the smell stay in your pocket or treat bag?
A fabric treat pouch that has held liver treats for several training sessions will take on a faint liver smell that does not wash out easily. This bothers some handlers; others consider it a non-issue because it further charges the pouch as a scent cue for the dog.
If you want to avoid permanent odor transfer, use a silicone treat pouch rather than fabric — silicone does not absorb odors and can be washed with dish soap. Alternatively, line a fabric pouch with a small zipper bag inside it.
Comparison with other treat smells
Stewart liver sits in the middle of the smell spectrum for high-value dog treats. It is more pungent than soft baked treats or commercial biscuits, less pungent than sardine-based treats or green tripe. Salmon-based freeze-dried treats tend to smell stronger and persist longer on hands. If liver smell bothers you but you need high-value rewards, chicken liver or salmon alternatives are worth comparing — though many handlers report that chicken liver freeze-dried treats are actually stronger-smelling than beef liver.
