Macadamia Nuts and Dogs: Weakness Without a Home Antidote
Dogs: Deadly toxin classification on this site—none. Call the same day after any macadamia exposure, especially if the dog cannot stand well.
Macadamia nuts can make dogs weak in the hind legs, tremulous, and feverish within hours. Cookies and trail mix count. Most dogs recover with clinic support, but the weakness can look like a spinal emergency until a veterinarian sorts it out.

2. What happens after macadamias
An unidentified toxin in macadamia nuts causes temporary weakness, especially in the back legs, plus vomiting, tremors, and a high temperature in some dogs. Signs often start within 12 hours. The toxin is not something you reverse with a home antidote.
