Autumn crocus is extremely toxic for dogs
Colchicum autumnale 
The autumn crocus is an 8-25 cm tall perennial herbaceous plant with leaves and flowers that sprout from the ground. They have a brown bulb. The green leaves, up to 40 cm long, appear in spring. The striking flowers come in autumn and are mostly pink to purple and can also be almost white in rare cases. They are very similar to crocuses and many a person has wondered about flowering crocuses in autumn.
All parts of the autumn crocus are poisonous, but especially the bulb, the flowers and the seeds. The tropane alkaloids contained in autumn crocus are highly toxic to dogs and can lead to severe kidney problems and even organ failure. This is why it is so important to act quickly if you suspect your dog has been poisoned by the autumn crocus.
Autumn crocus is also known as:
- meadow saffron
- naked ladies

There are different methods to remove the poison from the body:
1. ACTIVATED CHARCOAL: Activated charcoal can absorb toxins. If possible, it should be administered within 2 hours after ingestion of the poison, so that the toxin does not enter the bloodstream.
2. LAXATIVES: The vet may combine the administration of activated charcoal with a laxative.
3. VOMITING: The vet can also induce vomiting using medication to remove the toxin from the body.
In addition, the veterinarian can alleviate the symptoms and, depending on the degree of poisoning, stabilise the body functions with medication, as well as infusions and artificial respiration. If available, the administration of the antidote can also be helpful.
