This fruit can be dangerous for your dog and many don’t know it

By Vitia

Dogs are part of the family and, as such, we often want to share with them what we eat. A piece of fruit seems harmless, even healthy. However, not all fruits are safe for your pet: some can cause everything from digestive upset to severe poisoning.

The surprising thing is that many owners are unaware of which ones are really dangerous and which ones can be part of a balanced diet. Knowing this difference can save your dog’s health.

What fruits should I not give my dog?

Although fruits are often associated with natural and healthy foods, certain varieties contain substances that are toxic to dogs:

  • Grapes and raisins: They can cause acute kidney failure, even in small amounts.
  • Cherries: Their pits and stems contain cyanide, a highly toxic substance.
  • Avocado: Contains persin, which can cause vomiting, diarrhea, and heart problems.
  • Citrus fruits (lemon, orange, grapefruit): in excess they generate stomach irritation and nervousness.
  • Persimmon and apple or pear seeds: they contain small doses of cyanide and can clog the digestive tract.

Fruits that are beneficial for your dog

Not all fruits are bad; on the contrary, some are an excellent supply of vitamins, fibre and antioxidants:

  • Apple (seedless and coreless) – good for digestion and dental health.
  • Banana: rich in potassium and energy, ideal as an occasional treat.
  • Blueberries: natural antioxidants that strengthen the immune system.
  • Watermelon (seedless and peeled): refreshing and moisturizing on hot days.
  • Strawberry: promotes heart health and provides vitamin C.

How to introduce fruits into your dog’s diet

Adequate quantity

Fruits should be given as an occasional treat, not as a basis for food. 10% of the daily diet is more than enough.

Safe preparation

  • Wash each fruit thoroughly before giving it to her.
  • Remove seeds, bones, and hard shells.
  • Cut into small pieces to prevent choking.

Watch your pet

Every dog is different. Introduce the fruits little by little and see how it reacts. If you notice vomiting, diarrhea, or itching, stop immediately.

Practical tips

  • Always consult with your veterinarian before incorporating new foods.
  • Avoid canned or candied fruits: they contain added sugars and harmful preservatives.
  • Natural treats: fresh fruits can replace processed treats, but always in small portions.
  • Refrigerated in summer: watermelon or cold apple can be a refreshing snack for hot days.
