Is cooked quince flesh safer or more dangerous for a 20 kg dog compared to a regular apple? What

Short answer

Cooked quince flesh is similarly safe in small amounts, just like apple flesh. The main difference is that quince seeds, like apple seeds, contain cyanogenic compounds, but quince is often cooked whole, so seeds are more likely to be present. You should always remove the core and seeds from both fruits before offering a small piece to your dog. The risk from a few accidentally ingested seeds is low for a medium-sized dog, but it's best to avoid them. Stick to a bite-sized piece of cooked, seedless flesh as an occasional treat and watch for any signs of stomach upset.

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.
