What are the benefits of tomatoes to dogs?

Dogs should already be getting the nutrients they require from their regular dog food diet but it doesn’t hurt to supplement it with fruits and vegetables that are packed with important nutrients. Tomatoes, for example, can be beneficial to dogs because they are a rich source of vitamin C. They also contain lycopene, a powerful antioxidant that may help reduce the possibility of cancer in dogs.

Tomatoes are also part of the water-rich food family. One tomato could consist of 95% water! On a hot summer day, they could make a great treat for dogs to stay hydrated, especially if they aren’t drinking as much water as they should be.

Can tomatoes hurt your dog?

Yes, certain parts of the tomato can make your dog sick so it’s important to prepare the tomatoes correctly before you let your dog eat them. Tomatoes are part of the nightshade family so it’s important to remove the green parts of the plant such as the stem and leaves.

These parts of the tomato plant contain solanine, which can cause a variety of health problems like gastrointestinal upsets and difficulty in breathing. This would also be the reason why you must only feed your dog ripe tomatoes as green tomatoes will contain solanine.

Please note different rules apply for tomato-based foods like tomato sauce and ketchup as they are likely to contain ingredients that are toxic to dogs.

How much tomato can a dog eat?

This will depend on factors like how big your dog is (in weight and size) and the type of tomato you let your dog eat. For example, it may be fine to let your dog eat one or two tomatoes if it is of the smaller variety such as cherry tomatoes. If this is the first time then just feed your dog a tiny amount and see how he or she reacts to it.
