Is a slice of cooked quince safer or more dangerous than a slice of apple for my 7 kg small breed

Short answer

Cooked quince is slightly more risky than apple for your small dog. While the cooked flesh of both fruits is generally safe in small amounts, quince seeds contain cyanogenic compounds that can release cyanide if chewed and ingested. Apple seeds also contain these compounds, but quince seeds are often larger and more concentrated. The main rule is to always remove all seeds and cores before offering any fruit. If your dog ate a small, seedless piece of cooked quince, just watch for mild stomach upset and call your own vet if you notice vomiting or diarrhoea.

Cooked flesh is safe in small amounts. The seeds contain cyanogenic compounds.

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

Quince 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

Stone-fruit pits and some seeds release cyanide when crushed, and quite apart from that they are a choking and blockage hazard.
