Why a 10 kg dog can't handle even a handful of sprouts
A dog your size eating several raw potato sprouts is in real danger — the solanine in them hits harder per pound than in larger animals. At this quantity, the alkaloids can overwhelm their system fast, attacking nerves and digestion. You might notice excessive drooling first, then stumbling or confusion as the toxin spreads. Time matters here: the sooner treatment starts, the better their chances.
Smaller amounts might cause just stomach upset, but "a handful" for a 10 kg dog crosses into urgent territory. Their body can't neutralize solanine like ours can, and symptoms often escalate unpredictably. Watch for tremors or rapid breathing — these mean the vet can't wait.
Cooked skins aren't the safe alternative you hope for
Boiling or baking doesn't break down solanine in green-tinged skins or old potatoes — heat just softens the danger. If you're thinking of sharing leftover roast potatoes later, check every piece for green spots first. One unpeeled wedge with chlorophyll could deliver another dose of toxin when their system's already stressed.
The real risk is assuming cooking "fixes" potatoes like it does for other foods. Unlike bacteria, solanine's poison structure stays intact at high temperatures. Safe scraps for dogs come only from fully peeled, fresh, white-fleshed tubers with no eyes or sprouts.
Two separate risks needing different actions
The sprouts your dog just ate demand immediate care — call the vet en route if they're showing any odd behavior. For future meals, this isn't about portion control but strict avoidance. A single green skin fragment holds enough solanine to reignite trouble, especially after the initial exposure.
Separate your emergency response (vet now for the raw sprouts) from prevention (no potato skins ever). Dogs that recover from solanine poisoning often develop lasting sensitivity, making repeat incidents more severe. Lock away all potato waste, including peels and spoiled bits they might scavenge.
What the next 12 hours could look like
First symptoms usually appear within 2-4 hours — vomiting may seem like a good sign (expelling toxin), but it doesn't eliminate what's already absorbed. Lethargy or dilated pupils mean the solanine is affecting their nervous system. At the clinic, they'll likely give IV fluids and medications to protect the gut and heart.
Without treatment, solanine poisoning can cause paralysis or coma in dogs by disrupting nerve signals. Even if they seem okay at first, internal damage might not show for days. Post-visit, expect 24-48 hours of close monitoring for delayed reactions like irregular heartbeat or muscle twitches.
