Short answer

This is an emergency — go to a vet now. A single human baclofen tablet (10–20 mg) is an enormous dose for an 8 kg dog and can cause deep sedation, tremors, and slow breathing within hours. Do not wait to see whether symptoms appear; the drug absorbs steadily and the window for effective treatment is measured in hours. Bring the pill bottle and any leftover stew so the vet can calculate the exact exposure. The ASPCA poison line is 888-426-4435 if you cannot reach your own clinic.

How stew changes absorption for an 8 kg dog

The fatty chicken stew accelerates baclofen absorption compared to an empty stomach, meaning symptoms could appear within 30–60 minutes. Even a quarter of a standard 10 mg human pill delivers 1.25 mg/kg to your dog—five times the veterinary dose for muscle relaxation. Vomiting may occur but isn't reliable for removing the drug once the stew starts digesting.

Watch for early signs like exaggerated swallowing or sudden clumsiness—these often precede full collapse. The drug's effects peak around four hours after ingestion and can last over 24 hours in small dogs. Your vet may administer IV lipids to bind the medication before more enters the bloodstream.

Why you can't wait for symptoms

Baclofen suppresses the nervous system progressively—by the time you notice obvious weakness, the drug has already compromised breathing reflexes. An 8 kg dog showing mild sedation now could be non-responsive in two hours. Blood pressure drops are especially dangerous for small breeds; vets often preemptively give medications to support circulation.

Bring the exact pill bottle to the clinic—treatment varies whether it was a 10 mg or 20 mg tablet. Even if your dog seems normal upon arrival, hospitalization for 12–24 hours of monitoring is standard because effects can appear delayed with food in the stomach. Don't attempt home remedies; activated charcoal requires professional dosing to avoid aspiration.

The first hour determines outcomes

Vets can give reversal agents like physostigmine if given within 90 minutes of ingestion, but these become risky later as drug levels fluctuate. Your dog's size means even stomach pumping may be considered—a procedure too dangerous for larger animals but sometimes viable for small patients where every milligram counts.

Respiratory support is the top priority once the drug takes effect. Clinics prepare intubation kits for baclofen cases because jaw relaxation can obstruct airways suddenly. Small dogs often need heated IV fluids to maintain body temperature as the drug depresses their metabolism.

Longer-term concerns after exposure

Some dogs experience rebound hyperactivity as the drug wears off—your vet may recommend a quiet recovery space away from stairs. Temporary incontinence is common due to muscle relaxation; puppy pads help during the 24–48 hour recovery period. Follow-up bloodwork checks for secondary effects on kidney function, though these are rare with prompt treatment.

Future medication safety requires dog-proof containers—baclophen's sweet coating attracts curious pets. Ask your vet about pet-safe alternatives if you need muscle relaxants at home. Documenting this incident helps veterinarians estimate appropriate reversal doses if accidental exposure happens again.
