Yes, crabapple is mildly toxic to dogs when they chew the seeds, stems or leaves; the fruit flesh itself is safe.

Also known as: Wild Apple, Flowering Crabapple · Malus spp.

What makes it toxic

Cyanogenic glycosides concentrated in seeds, stems and wilted leaves, which can release cyanide when crushed and swallowed. Fruit flesh lacks these compounds.

Warning signs to watch for

Drooling, vomiting and diarrhea after chewing seeds or leaves. A dog that eats many wilted leaves could show weakness or breathing difficulty.

What to do if your dog eats it

Note what was eaten — flesh, seeds or leaves. Flesh means simple monitoring; seeds or leaves mean rinsing the mouth and calling your vet if symptoms appear.

Common questions

Is it safe for my dog to eat crabapples off the lawn?

The fruit flesh is fine in small amounts, but dogs that crunch the whole fruit swallow seeds. Limit snacking and discourage leaf chewing.

How many seeds are dangerous for a dog?

The cyanide dose is very small per seed, and most dogs show only mild upset. Still, chronic seed eating should be stopped and large leaf ingestions reported to a vet.
