Safeguarding your dog from toxic autumn and winter plants

🍂 Autumn & Winter Plants & Flowers Toxic to Dogs and Cats: What Owners Should Know

As autumn arrives and winter approaches, many gardens and woodlands change dramatically — and some seasonal plants can pose risks to curious pets. Dogs often explore by sniffing, digging, and chewing, so knowing which plants are toxic can help you keep them safe during colder months.

🌱 Toxic Autumn and Winter Plants for Dogs and Cats

These plants are known to be poisonous if ingested:

• Autumn Crocus – All parts are highly toxic to dogs and cats.

• Chrysanthemums – Can cause vomiting, diarrhoea, and skin irritation.

• Oleander – Extremely poisonous; even small amounts can be dangerous.

  
  

🚨 Acorns & Conkers: Common Autumn Hazards

These seasonal favourites can be harmful if eaten:

⚠️ Acorns

Contain tannins that may cause stomach upset and, in severe cases, more serious complications. Signs may include vomiting, diarrhoea, dehydration, or collapse. Contact your vet immediately if your dog has eaten acorns.

⚠️ Conkers

Conkers contain aesculin, a toxic compound. Ingestion can lead to vomiting, diarrhoea, drooling, abdominal discomfort, tremors, or difficulty walking. Conkers can also cause blockages. Seek urgent veterinary advice if your dog eats one.

Tip: Supervise outdoor adventures and prevent access to fallen acorns and conkers.

⚠️ Possible Signs of Plant Poisoning

Symptoms vary depending on the plant and the amount eaten, but may include:

• Vomiting or diarrhoea

• Restlessness or abdominal pain

• Lethargy

• Tremors or unsteady movements

• Sudden collapse

  
  

🐾 What To Do If You’re Concerned

If you suspect your dog has eaten a toxic plant:

• Act quickly — don’t wait for symptoms to worsen.

• Contact your vet or an emergency service for guidance.

• Provide details — identifying the plant and estimating the amount eaten can help your vet assess the situation.

  
  

🌿 After Veterinary Care

Once your vet has confirmed it is safe to feed your dog their next meal, you may wish to focus on supporting normal gut function for a few days. Our Short‑Term Recovery blog explains this process in more detail.

A simple short‑term feeding approach may include:

• Boiled boneless chicken, turkey, or white fish

• A small amount of cooled cooking liquid

• A gut‑support product such as Dorwest Tree Barks or Proflax Tummy Tastic  

• Dog‑safe bone broth such as Alexander's Natural or Karnlea 

Follow this until your vet advises otherwise, then gradually return to raw with gentle proteins such as turkey or chicken for a few days.

🧡 Ongoing Care

Monitor your dog closely during recovery and always consult your vet before making changes to their diet or care routine. Staying aware of seasonal hazards can help keep your dog safe throughout autumn and winter.
