My 7 kg Pomeranian ate a few leaves of arugula from a salad bowl with dressing, but my 25 kg Labrador didn't touch it. Do I need to treat them differently?

Short answer

Only the Pomeranian needs watching. The arugula itself is safe, but the dressing likely contains onion, garlic, or too much salt and fat. For a small dog, even a little can cause stomach upset. Watch the Pom for vomiting, diarrhoea, or loss of appetite over the next 12 hours. The Labrador is fine. There's no need to separate them or treat the unaffected dog. Just offer the Pomeranian plenty of water and feed her next meal as usual unless she seems unwell.

Why size matters with salad toppings

A 7 kg Pomeranian eating dressed arugula faces different risks than a larger dog would. The leaves themselves aren’t the issue—it’s what they carried. Salad dressings often contain garlic powder, onion, or excessive salt, which are far more dangerous per gram of body weight. Your Lab’s size makes accidental ingestion negligible, but for the Pom, even a teaspoon of dressing could irritate their stomach lining or trigger mild toxicity.

Watch for subtle signs like lip-licking, pacing, or refusing their next meal. Smaller dogs dehydrate faster if vomiting starts, so note how much water they drink. The Labrador’s lack of interest in the salad means no action is needed for them, but keep human food out of reach—their curiosity might not stay dormant.

Timing of symptoms in a small dog

Reactions to onion or garlic compounds don’t always appear immediately. For your Pomeranian, the first 6–12 hours may only show mild lethargy or a slightly tender abdomen when picked up. More concerning signs—like repeated gagging or diarrhea with mucus—typically develop within 24 hours if they’re going to appear at all.

Don’t wait for severe symptoms if you know the dressing contained alliums. Small breeds can progress from seeming fine to needing fluids quickly. Mark the time of ingestion now; if the Pom skips two meals or acts uncomfortable lying down, that’s your cue to call the vet.

Handling potential fat overload

Rich dressings often mean oils or dairy, which small systems struggle to process. A few leaves coated in ranch or blue cheese could deliver more fat than your Pom’s pancreas expects, leading to gurgling sounds or loose stools later. Unlike allium toxicity, these symptoms usually start within 4–6 hours and resolve faster.

Offer ice cubes instead of a full water bowl to prevent gulping, which can trigger vomiting. Plain boiled chicken (no skin or seasoning) helps settle their stomach if they’re hungry after 12 hours. The Labrador’s larger body can handle incidental fat better, but it’s still wise to keep all dressings away from both dogs in the future.

When to intervene for the Pomeranian

One episode of vomiting isn’t an emergency, but watch the pattern. If your Pom brings up foam or yellow bile more than twice, or can’t keep water down, they risk dehydration. Their small size means fluid loss happens faster than you might expect—check for dry gums or a slow skin tent test on the scruff.

Labored breathing or dark red gums are red flags suggesting possible allium toxicity, not just stomach upset. Your Lab’s safety means you can focus entirely on the Pom’s symptoms. Have your vet’s number ready; small dogs often need earlier intervention than larger ones with the same exposure.
