Signs of Lantana Poisoning in Dogs
If a dog ingests lantana, symptoms can appear within a few hours. The severity of symptoms often depends on the amount consumed and the dog’s size and health. Here are some common signs to watch for:
Gastrointestinal Distress
Vomiting, diarrhea, and abdominal pain are often the first signs that a dog has ingested lantana. These symptoms can be mild or severe, depending on the quantity consumed.
Neurological Symptoms
In more severe cases, dogs may show signs of neurological distress, including tremors, disorientation, or seizures. These symptoms indicate a more severe reaction to the toxins.
