Short answer

After veterinary treatment, you'll need to monitor your dog closely at home for at least 24-48 hours. Watch for any return of symptoms like restlessness, panting, vomiting, tremors, or a racing heart. Ensure they have a quiet place to rest and offer small amounts of water and bland food if your vet approves. Recovery can take a few days, and follow-up blood tests might be needed to check for lingering effects. Always follow your vet's specific discharge instructions and contact them immediately if any worrying signs reappear.

The first night home with a 15 kg dog

Your dog's size means they processed theobromine slower than a smaller animal, but veterinary treatment has likely interrupted the worst effects. Tonight, set up a quiet space away from stairs or excitement — chocolate toxicity can cause disorientation even after IV fluids. Keep water available but don't force drinking; vomiting may still occur if their stomach remains irritated from treatment.

Check their gums every few hours: pale or bright red gums can signal lingering cardiovascular effects. Dark chocolate often causes muscle tremors that reappear in waves, so have thick towels ready to pad their bed if shaky legs return. Note any pacing or inability to settle — this suggests continuing stimulant effects needing follow-up care.

Next-day food and movement precautions

If your vet approved food, offer boiled chicken and rice in tablespoon portions every 3-4 hours. Avoid fatty foods that could trigger pancreatitis after chocolate's strain on their system. Leash-walk only for bathroom breaks — elevated heart rates from theobromine make overexertion risky for another 48 hours.

Record resting breathing rates: more than 30 breaths per minute while sleeping may indicate unresolved toxicity. Collect any diarrhea samples showing undigested chocolate, as this confirms ongoing absorption. Hydration is key — pinch the skin at their shoulders; if it doesn't snap back immediately, call your vet about sub-q fluids.

Late-stage symptoms that demand callback

Between 24-36 hours post-ingestion, some dogs experience rebound hyperactivity as metabolites peak. Sudden barking at nothing or shadow-chasing warrants an immediate vet update. Likewise, any coffee-ground vomit or seizures mean you should return to emergency care without delay.

Monitor urine output closely — difficulty urinating or dark brown urine suggests muscle breakdown from prolonged tremors. Chocolate's diuretic effect may have them drinking excessively; sudden water refusal is equally concerning. Keep other pets away during recovery to prevent stress-induced complications.

Longer-term watchpoints for holiday incidents

Holiday chocolate often contains raisins or macadamia nuts — if your dog scavenged alongside wrappers, watch for additional symptoms like joint stiffness or weakness. Holiday stress also masks symptoms; note if they retreat more than usual after seeming better.

Over the next week, check for weight loss indicating missed pancreatic issues. Some dogs develop temporary light sensitivity after theobromine exposure — squinting or avoiding bright rooms deserves mention at their recheck. Save all treatment records; chocolate toxicity can affect future anesthesia protocols.
