What happens if I give my 10 kg dog a few dried goji berries every day alongside his heart medication?

Short answer

Feeding goji berries daily to a dog on medication is not recommended. While a couple of dried berries are not acutely toxic, they can interact with certain medications, including heart drugs, and potentially alter their effectiveness. Over time, the high sugar content in regular servings can also contribute to weight gain or dental issues. It's best to avoid making goji berries a daily treat, especially for a dog with a known health condition. Stick to vet-approved snacks and monitor your dog closely; if you notice any changes in behavior or health, call your own vet for advice.

A couple of dried berries are not toxic, but they can interact with medication and are high in sugar.

Dogs and cats carry the same rating (Feed with care), so the notes below hold for either pet.

Goji berry is not poisonous to dogs, but it is easy to over-feed. Rich fat, salt or seasoning can bring on vomiting or diarrhoea within a day, and repeated large portions are a recognised trigger for pancreatitis.

If it ate some before you noticed, watch for vomiting, diarrhoea, loss of appetite, unusual tiredness or a painful, swollen abdomen over the next 24 hours. A one-off small amount in a healthy adult usually passes with water and rest; repeated exposure, a puppy or kitten, a senior, or a pet with an ongoing illness is a reason to call your vet the same day.

Why these cautions matter

Added sugar brings empty calories, and over months that means weight gain and dental disease — both far harder to undo than to avoid.
