Why a 3 kg dog’s size changes everything
A lick from a green potato sprout delivers more toxin per pound to a small dog than it would to a larger one. Solanine isn’t diluted by body mass as effectively here, so even minor exposure can trigger symptoms like drooling or stomach pain. Watch for subtle changes—panting when she hasn’t exercised, or turning her nose up at food she’d usually beg for.
The sprout’s rough surface may have left microscopic irritants on her tongue, which could cause pawing at her mouth within the next hour. Avoid offering water right away—it might spread residual toxins. Instead, wipe her gums gently with a damp cloth to remove any plant residue while you call your vet.
Two signs you wouldn’t expect from one lick
Most owners watch for vomiting, but solanine also causes dilated pupils or sudden sensitivity to light. If she squints in a normally bright room or her eyes look unusually black, note the time. These neurological effects can escalate to tremors if untreated.
Her gums might not pale immediately—check where they meet her teeth for a whitish line. Lethargy could masquerade as napping; try calling her to a favorite toy. If she moves slowly or seems disoriented, skip the wait-and-see approach.
Why the next 90 minutes matter most
Solanine peaks in the bloodstream quickly. Even if she seems fine now, set a timer for an hour from exposure. That’s when early gastrointestinal signs often start—restlessness, lip-licking, or a hunched posture. Keep her confined where you can observe these subtle cues.
Don’t rely on home remedies like milk or bread. They won’t neutralize the toxin and could delay professional care. Have her leash and carrier ready; vets may want to administer IV fluids to protect her kidneys from circulating toxins.
When to bypass the vet call and go straight in
If she develops muscle twitches or can’t settle—pacing then collapsing suddenly—head to the ER. These indicate advancing neurological involvement. Smaller dogs decompensate faster, so waiting for multiple symptoms is riskier.
Bring the sprout or a photo of the plant. Emergency teams can estimate toxin load better if they see how mature the sprouts were. Darker green or longer sprouts concentrate more solanine than pale nubs.
