Yes, a poisoned dog might still eat, depending on various factors. When a dog is poisoned, it can experience a range of symptoms like nausea, vomiting, and abdominal pain. However, some poisons may not immediately affect their appetite or may cause increased thirst. It’s crucial to note that a dog’s response to poisoning can differ based on the type and amount of poison ingested. I had an experience with a poisoned dog that still showed interest in food, unaware of the danger. Nonetheless, regardless of their eating behavior, immediate vet attention is critical when poisoning is suspected to prevent further harm.
