Can Dogs Eat Tomatoes? Everything You Need to Know

Tomatoes are a staple in many households, but if you’re a dog owner, you might wonder whether they’re safe for your furry friend. The answer is yes and no—ripe, red tomatoes are generally safe for dogs in moderation, but green tomatoes and the plant itself can be toxic. Tomatoes belong to the nightshade family, which means they contain tomatine and solanine, compounds that can be harmful in large quantities. While ripe tomatoes contain only trace amounts of these toxins, unripe tomatoes, stems, and leaves have higher concentrations, posing a risk to dogs.

Are Tomatoes Toxic to Dogs?

Ripe tomatoes are non-toxic and can be a healthy treat, packed with vitamins A, C, and K, as well as antioxidants and fibre. However, green tomatoes, stems, and leaves contain tomatine, which can lead to tomatine poisoning if consumed in large amounts. Symptoms of poisoning include vomiting, diarrhoea, loss of coordination, muscle weakness, and irregular heartbeats. While severe cases are rare, it’s best to avoid feeding your dog unripe tomatoes or any part of the tomato plant.

How Much Can Dogs Eat?

If you want to share tomatoes with your dog, small amounts of ripe, red tomatoes are safe. A few slices as an occasional treat can provide nutritional benefits, but they should not replace a balanced diet. Dogs with sensitive stomachs or acid reflux should avoid tomatoes, as they may cause gastrointestinal upset. Additionally, processed tomato products like sauces, soups, and ketchup often contain salt, sugar, and artificial additives, which can be harmful to dogs.

Side Effects of Dogs Eating Tomatoes

Even ripe tomatoes can cause mild side effects in some dogs. Possible reactions include:

• Upset stomach (vomiting or diarrhoea)

• Allergic reactions (hives, coughing, difficulty breathing)

• Acid reflux (discomfort after eating tomatoes)

If your dog shows any of these symptoms, stop feeding them tomatoes and consult a veterinarian.
