Can a Newfoundland Eat Macadamia Nuts?

Verdict: ❌ NO

Why Macadamia Nuts Are Dangerous for Newfoundlands

Despite their massive size, Newfoundlands are just as susceptible to the toxins found in macadamia nuts as any other dog breed. Macadamia nuts contain compounds that are toxic to dogs, affecting their neurological system and overall metabolic function.

Giving a macadamia nut to your Newfoundland—or letting them scavenge one from a party platter—can lead to rapid onset of toxicity.

Potential Risks & Symptoms

There are no nutritional benefits to macadamia nuts for dogs; there are only significant risks. If your Newfoundland ingests these nuts, you may notice the following symptoms within 12 hours:

• Hind Leg Weakness: Difficulty walking or “stumbling” (ataxia).
• Vomiting & Diarrhea: Gastrointestinal distress is common.
• Hyperthermia: An increase in body temperature.
• Lethargy: Extreme tiredness or depression.
• Tremors: In severe cases, muscle shaking or seizures may occur.

What to Do If Your Newfoundland Ate Macadamia Nuts

Because macadamia nuts are toxic, this is considered a veterinary emergency. Do not wait for symptoms to appear before taking action.

1. Call Your Vet Immediately: Contact your primary veterinarian or the nearest emergency animal clinic.
2. Contact Poison Control: You can call the ASPCA Animal Poison Control Center or the Pet Poison Helpline.
3. Identify the Amount: Try to determine exactly how many nuts your dog consumed and how long ago it happened. This helps the vet determine the level of toxicity.
4. Do Not Induce Vomiting unless specifically instructed to do so by a veterinary professional.
