What is a common clinical sign of macadamia nut toxicity related to muscle function?

The correct answer highlights muscle weakness as a common clinical sign of macadamia nut toxicity. When pets, particularly dogs, ingest macadamia nuts, it can lead to a range of symptoms due to the toxic compounds found in the nuts. One of the notable effects is the inhibition of normal muscle function, which manifests as weakness. This weakness can affect a dog's ability to stand or walk properly and may be accompanied by lethargy.

In macadamia nut toxicity, the neuromuscular system is particularly impacted, but the weakness is primarily due to the way the toxins interfere with normal muscle signaling and contraction. Dogs exhibiting this sign may struggle with coordination and overall strength, making it critical for pet owners to recognize and seek veterinary care if macadamia nuts are ingested.

Understanding the implications of muscle weakness in this context emphasizes the importance of awareness regarding toxic foods for pets, particularly for those who may enjoy snacking on human food.
