Tomatoes can be safe for dogs if they are ripe and consumed in small amounts. Ripe tomatoes contain vitamins A and C, as well as antioxidants that can support the immune system and overall health. However, the green parts of the plant (leaves, stems, and unripe tomatoes) contain a toxic substance called solanine, which can cause poisoning in dogs, leading to stomach issues, weakness, and excessive drooling.
Ripe tomatoes should be given to dogs in very small quantities without any salt, oil, or spices. They should not be a regular part of the dog's diet and should only be offered as an occasional treat.
Tomatoes for Cats
Tomatoes can also be safe for cats if they are fully ripe and offered in small quantities. Ripe tomatoes may contain vitamins and antioxidants beneficial for a cat’s health. However, the green parts of the plant and unripe tomatoes contain solanine and tomatine, which are toxic to cats and can cause poisoning, leading to digestive problems and irregular heartbeat.
Cats can be given ripe tomatoes in very small amounts, only as a rare treat. Tomatoes should not replace meat-based components of a cat’s diet, as cats are obligate carnivores and require primarily meat to stay healthy.
