Blood sugar monitoring for the next 24 hours
Even with IV dextrose, your 15 kg dog's glucose levels may seesaw for hours. The vet will test him every 1-2 hours initially, watching for rebounds—some dogs swing from hypoglycemia to hyperglycemia as their pancreas overreacts. They'll taper the dextrose slowly rather than stopping abruptly to prevent crashes.
You might notice him sleeping deeply at first; that's normal as his brain recovers from sugar starvation. But if he remains unresponsive to touch or voice after 6 hours, ask the vet to reassess—prolonged stupor can indicate brain swelling or liver complications.
Liver enzyme tracking over 48 hours
Xylitol's liver effects often lag behind the sugar crisis. The vet will run ALT and AST tests at least twice—once during treatment and again before discharge. Rising enzymes mean he needs liver protectants like SAMe or IV fluids to flush toxins. Yellow tinge to his gums or whites of his eyes would confirm trouble.
Ask for a copy of his blood work. Even if values are normal at discharge, recheck them in a week—delayed liver damage sometimes appears later. At home, watch for vomiting, lack of appetite, or dark urine, which could signal late-stage issues.
Home recovery expectations
For the first two days, offer small, bland meals every 4-6 hours to maintain steady glucose. Boiled chicken with rice works, but add a bit of honey if he seems lethargic between meals. Avoid fatty foods—his liver needs gentle support. Keep water always available; dehydration worsens liver stress.
Limit activity for 3-5 days. Dogs recovering from hypoglycemia often seem back to normal quickly, but overexertion can trigger relapse. No off-leash running or intense play until his follow-up bloodwork clears him.
When to call the vet post-discharge
If he refuses two meals in a row or starts vomiting, call immediately—these suggest lingering liver or pancreatic issues. Also report any odd behavior like circling, head pressing, or temporary blindness, which could indicate brain damage from prolonged hypoglycemia.
Keep a log of his eating, drinking, and energy levels. This helps the vet spot trends—for example, gradual decrease in appetite might mean developing liver dysfunction. Most dogs recover fully with prompt care, but detailed tracking ensures no complication goes unnoticed.
