I've been sprinkling poppy seeds on my senior dog's food every day for three weeks—is this safe for an older dog?

Short answer

Poppy seeds contain trace amounts of opiates that can accumulate with repeated daily exposure, and this is especially a concern for senior dogs whose livers and kidneys process substances more slowly. While a few seeds on a bagel are harmless, daily feeding over three weeks could lead to detectable levels in your dog's system. Watch for unusual drowsiness, constipation, or changes in behavior. Consider stopping the daily addition and mention this habit at your next veterinary visit.

Poppy seeds 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.
