Are quince poisonous to dogs?

Onions, garlic and chives in all forms (dry, raw, cooked) contain thiosulphate, which can irritate the gastrointestinal system of your dog. A relatively high dosage (600-800 grams) in one meal or spread apart over a few days can damage red blood cells (haemolytic anaemia)[2].





Grapes and Raisins: Grapes and raisins can cause kidney failure in dogs. As little as a single serving of raisins can kill a dog


Chocolate: Chocolate can cause seizures, coma and death. Baker’s chocolate is the most dangerous. A dog can consume milk chocolate and appear to be fine because it is not as concentrated, but it is still dangerous.


Coffee, Coffee grounds, tea and tea bags: Drinks/foods containing caffeine cause many of the same symptoms chocolate causes


Macadamia Nuts: Macadamia nuts can cause weakness, muscle tremor and paralysis.


Animal fat and fried foods: Excessive fat can cause pancreatitis.


Bones: Bones can splinter and damage a dog’s internal organs.


Tomatoes: Tomatoes can cause tremors and heart arrhythmias. Tomatoe plants and the most toxic, but tomatoes themselves are also unsafe.


Avocados: The fruit, pit and plant are all toxic. They can cause difficulty breathing and fluid accumulation in the chest, abdomen and heart


Nutmeg: Nutmeg can cause tremors, seizures and death


Apples, Cherries, Peaches and similar fruit: The seeds of these fruits contain cyanide, which is poisonous to dogs as well as humans. Unlike humans, dogs do not know to stop eating at the core/pit and easily ingest them.


Raw eggs: Raw eggs can cause salmonella poisoning in dogs. Dogs have a shorter digestive tract than humans and are not as likely to suffer from food poisoning, but it is still possible.


Salt: Excessive salt intake can cause kidney problems.
