Why a handful is a meal for the terrier but a garnish for the retriever
That same handful—perhaps 2 tablespoons—represents about 1% of the big dog’s daily intake but nearly 6% of the small one’s. Canine stomachs react to volume shifts more than toxicity here. The terrier might experience a noticeable slowdown in digestion, leading to a fuller belly or a skipped meal later, while the retriever processes it as a blip.
Watch the smaller dog’s next bowel movement: seeds can sometimes cause crumbly, dry stools in tiny bodies. The retriever will likely pass them unnoticed. Neither scenario is dangerous, but the terrier’s system is working harder relative to its size.
The choking paradox—small dogs, big seeds
Ironically, the larger dog is more likely to chew the seeds (still useless, as dogs don’t digest them well), while the small one may swallow them whole in a rush. Whole seeds pose a slight choking hazard if the terrier gulps them mid-play. Scatter feeding on a flat surface slows him down.
One sneaky risk for the tiny dog? Seed shells can mildly irritate the intestinal lining over time if consumed in bulk, leading to occasional mucus in stools. This isn’t an allergy—just mechanical irritation. The retriever’s wider intestinal diameter handles shells without fuss.
The calorie math you can’t see
At ~50 calories per tablespoon, that handful adds 100+ calories to the terrier’s daily limit—potentially 20% of his needs. For the retriever, it’s under 5%. While not toxic, habitual over-treating with seeds could nudge the small dog toward weight gain. Big dogs have more calorie wiggle room for empty snacks.
If you love sharing seeds, reserve them as training rewards for the terrier—a few at a time. The retriever can handle a post-dinner sprinkle without adjustments. Neither needs sesame nutritionally, but the size gap turns the same action into different impacts.
The "equal share" illusion in multi-dog homes
Dogs notice portion fairness, so giving both the same handful feels right—but it’s like giving a toddler and a teenager identical steak portions. For the terrier, measure seeds by the pinch (10–15 max) to match his jaw size. The retriever can have a loose handful without strict counting.
If the little one starts guarding or stealing seeds, it’s a sign he’s overvaluing them. Switch to smaller, separate treat times. The big dog’s enthusiasm for seeds is likely about your attention, not the seeds themselves—he’d be just as happy with an extra belly rub.
