No, dogs cannot typically overcome poisoning on their own. If a dog ingests something toxic, it’s crucial to seek immediate veterinary care. Many substances, such as certain foods, medications, household chemicals, and plants, can be toxic to dogs. Symptoms of poisoning vary but may include vomiting, diarrhea, seizures, or lethargy. I remember an incident when a friend’s dog accidentally ate chocolate. Despite thinking it would pass, the dog became very sick. We rushed to the vet, where they administered treatment that saved the dog’s life. Prompt action is vital; waiting could worsen the situation. Never assume a dog can recover without proper medical intervention if poisoning is suspected.
