Part 2: Garlic and Dogs: A Complicated Relationship

2.1 The Risks of Garlic for Dogs: A Silent Threat

1. While garlic offers potential benefits for humans, it poses a significant threat to dogs.
2. Garlic contains a compound called thiosulphate, which is highly toxic to dogs, even in small amounts.
3. Thiosulphate breaks down red blood cells, leading to anaemia, a condition characterized by a deficiency of red blood cells.
4. Garlic toxicity can also cause gastrointestinal distress, including vomiting, diarrhoea, and abdominal pain.
5. In severe cases, garlic poisoning can lead to organ damage, respiratory distress, and even death, particularly in small breeds or puppies.

1. Early detection is crucial for effective treatment. If you suspect your dog has ingested garlic, watch for the following symptoms:
2. Gastrointestinal upset: Vomiting, diarrhoea, abdominal pain, loss of appetite.
3. Weakness and lethargy: Your dog may appear tired, sluggish, and uninterested in its surroundings.
4. Pale gums: This is a sign of anaemia, which can be caused by garlic poisoning.
5. Rapid breathing and heart rate: This can indicate a decrease in oxygen levels due to damage to red blood cells.
6. Increased thirst: Your dog may drink more water than usual to compensate for dehydration caused by vomiting and diarrhoea.
7. Coma (in severe cases): This is a serious sign of severe garlic poisoning and requires immediate veterinary attention.

2.3 Factors Affecting Toxicity: Understanding the Risks

1. The severity of garlic poisoning depends on several factors, including:
2. Amount ingested: The larger the amount of garlic consumed, the more severe the symptoms.
3. Dog's size and weight: Smaller dogs are more susceptible to garlic toxicity due to their smaller body size.
4. Dog's overall health and breed: Dogs with pre-existing health conditions may be more vulnerable to garlic poisoning.
5. Form of garlic: Fresh garlic, cooked garlic, and garlic powder all contain thiosulphate and pose a risk to dogs.
