What vomiting reveals about solanine absorption
Your terrier's vomiting indicates the solanine has already triggered the chemoreceptor trigger zone in the brain. Unlike simple stomach upset, solanine-induced vomiting often occurs in quick succession with little warning. Since the potato was hidden under appliances, it likely had concentrated green areas from prolonged light exposure — these contain peak toxin levels.
Examine the vomitus for green flecks or skin fragments, which help estimate ingestion time. Dogs typically vomit within 30-90 minutes after solanine exposure, but delayed vomiting suggests slower gastric emptying. Immediately restrict movement — physical activity accelerates toxin circulation in this critical phase.
Why terriers show symptoms faster
Terrier breeds have heightened sensitivity to solanine due to their metabolic rate and typical muscle mass. The vomiting reflex is often just the first wave — watch for "fly-biting" motions (snapping at air) or sudden stiffness in the hindquarters. These signal neurological involvement requiring IV intervention.
Check capillary refill time by pressing on the gums: normal is under 2 seconds for pink return. Prolonged refill indicates cardiovascular impact from solanine's effect on heart muscle cells. Keep your dog cool — elevated body temperature increases toxin absorption rates through the gut lining.
The hidden danger of forgotten potatoes
Potatoes rolled under appliances undergo accelerated greening from warmth and humidity. What might be a mild toxin in fresh potatoes becomes concentrated in these forgotten specimens. Your terrier likely chewed thoroughly to extract the starchy interior, maximizing contact with the toxic skin.
Move appliances weekly to check for hidden hazards. If you store potatoes in bulk, invest in a root cellar or opaque airtight containers — even brief kitchen lighting can trigger solanine production. Consider training "drop it" using bitter spray-treated decoy potatoes for safety drills.
Emergency steps while arranging transport
Collect fresh vomit samples in glass jars (plastic may react with stomach acids). Note the time between vomiting episodes — intervals under 15 minutes warrant emergency protocols. Restrict water access despite the instinct to let them drink, as solanine causes paradoxical dehydration through fluid shifts.
Pad a carrier with towels to prevent injury during possible seizures. Take photos of the potato remnants showing the extent of green coloration. If multiple pets share the home, isolate them all until you confirm who ingested the toxin — terriers often steal food from others then show symptoms first.
