La ciencia detrás de esto
Las nueces de macadamia contienen una toxina no identificada que afecta de forma única el sistema neuromuscular de los perros. El compuesto causa debilidad reversible y ataxia en las extremidades traseras, probablemente a través de la alteración de la señalización de las neuronas motoras. A diferencia de muchas toxinas, el mecanismo exacto sigue siendo desconocido a pesar de décadas de observación clínica. La investigación de Morton (2002) estableció la DL50 en 2,4 g/kg. La toxina es termoestable y está presente en todas las formas: crudas, tostadas, saladas y en productos horneados. Los síntomas son dosis-dependientes y típicamente se resuelven en 12-48 horas con cuidado de soporte (ASPCA, 2023).
Calculadora de dosis tóxica
Cantidad ingerida: Dosis tóxica mínima: 0,5 g/kg de peso corporal (síntomas leves)
LD50: DL50: 2,4 g/kg de peso corporal (síntomas severos)
La ciencia detrás de esto: Fuente: Morton, 2002 — Journal of Veterinary Diagnostic Investigation
Ejemplo: Un perro de 15 kg (33 lb) que coma 15 g de nueces de macadamia (aproximadamente 12-15 nueces) alcanzaría el umbral tóxico mínimo. Una nuez típica pesa unos 1,2-1,5 g.
Cronograma de síntomas: qué esperar
Early signs: weakness in hind legs, ataxia (wobbly gait), vomiting
Progression: tremors, reluctance to stand, abdominal pain, elevated temperature (up to 104°F/40°C)
Resolution: symptoms typically resolve with supportive care; full recovery expected
Preguntas frecuentes
Are macadamia nuts toxic to dogs?
Yes, macadamia nuts are uniquely toxic to dogs. The exact toxin is unknown, but even small amounts cause weakness in hind legs, vomiting, tremors, and hyperthermia. The minimum toxic dose is approximately 2.4 g/kg of body weight. Most dogs recover within 48 hours with supportive veterinary care.
How many macadamia nuts are dangerous for a dog?
For a 20kg (44lb) dog, as few as 10-12 nuts can cause symptoms. Smaller dogs may react to just 2-3 nuts. The toxic threshold is approximately 0.5g of nuts per kg of body weight for mild symptoms, with severe symptoms appearing at 2.4g/kg.
How long after eating macadamia nuts will my dog show symptoms?
Symptoms typically appear within 3-12 hours after ingestion. The earliest sign is usually weakness or paralysis of the hind legs, followed by vomiting, tremors, abdominal pain, and elevated body temperature (up to 104°F/40°C).
Can a dog die from eating macadamia nuts?
Fatalities from macadamia nut poisoning are extremely rare. The LD50 is 2.4g/kg, meaning a 20kg dog would need to eat approximately 48g of nuts (about 40-50 nuts) to reach dangerous levels. However, even sub-lethal doses cause significant discomfort and require veterinary monitoring.
Should I induce vomiting if my dog ate macadamia nuts?
Do NOT induce vomiting unless instructed by a veterinarian. Induction is only effective within 30 minutes of ingestion and can cause aspiration pneumonia. Contact ASPCA Poison Control at (888) 426-4435 for specific guidance based on the amount consumed and time elapsed.
