Male fern is toxic for dogs

Dryopteris filix-mas toxic

The male fern loves shady places in forests, but is also found in gardens and parks. The male fern grows to about one metre high. Like almost all ferns, it has green, funnel-shaped leaves that are pinnate and stand in a rosette. The leaf margins are usually not curled and small, semicircular spores can be found on the underside of the leaves.

The entire male fern is poisonous, but especially the rhizome, the stems of the leaves and the young shoots. They have the highest content of poison in the summer months.
