Are Acorns poisonous to dogs? Our homes and yards are dangerous places when looked at from a child’s or pet’s point-of-view. Detergents, plants, and certain foods can all play a role in your dog’s overall wellness. Poison Control receives a number of calls every year asking whether acorns are poisonous to dogs?
Technically, the answer is yes, acorns are poisonous to dogs. However, a number of variables are at play here including exactly how many acorns the dog ate, the size of the dog, and the overall health of the dog otherwise.

Clinical Signs that Prove Acorns are Poisonous to Dogs
Acorn or oak poisoning happen within 3 to 7 days of eating a large number of acorns. Acorns and oak leaves are both toxic to dogs, and it is important to be aware of the following clinical signs if you suspect your dog has swallowed any.
#1 Intestinal Blockage
Dogs with intestinal blockage will have tender bellies, lack of appetite, weight loss, constipation, vomiting or diarrhea.
Small Dogs have a greater potential for experiencing intestinal blockage, depending on the amount eaten.
Large Dogs are also at risk, depending on the amount eaten. However, a large dog is more likely to be able to pass one acorn. Nevertheless, the more serious clinical indication would be whether the dog has an allergic reaction and how the toxins affect the organs.

#2 Swollen Lymph Nodes
Acorns are poisonous to dogs, and the situation is compounded if the dog is allergic to them.
Clinical Signs of an Allergic Reaction to Poisonous Oak includes swollen lymph nodes, raised bumps or skin swelling. The dog might be extremely itchy and, if not treated right away, the dog’s skin may blister and ooze.
Look for swollen lymph nodes by gently palpating your hand around the dog’s jaw, neck, shoulders, groin, and armpit.S
Jaundice, which involves yellowing of the skin and eyes, occurs when there is liver damage. This is a serious condition that must be treated right away. Look at the skin on the dog’s stomach where the fur is traditionally lighter (belly, armpits, groin). If you see any unusual yellowing skin or yellowing of the eyes, bring your dog to a licensed veterinarian.
NOTE: In the case of a brush with poison oak, the dog does not have to actually ingest the plant to experience toxic and allergic reactions. The chemical in the plant simply needs to brush against the dog’s skin.
#4 Worst Case Scenario
In the worst-case scenario of a dog being poisoned by acorns or oak leaves, a few things could happen:
- Kidney Failure
- Liver Damage
- Severe Respiratory Distress
#5 Best Case Scenario
In the best case scenario, the dog:
- ate only a very small amount for his/her size.
- was able to get treatment right away
- the toxicity of acorns did not damage the dog’s organs
- just because your dog ate ONE acorn doesn’t necessarily mean he/she will become sick. Again, there are a number of factors at play here including the size of the dog, the amount eaten, and whether the dog is allergic to them or not.

#7 What to Do If You Suspect Acorn Poisoning in Your Dog
- Phone the veterinarian and explain the clinical signs your dog is exhibiting.
- Tell the veterinarian if you suspect the dog may have eaten a poisonous plant.
- The veterinarian will be able to tell you whether this is a serious emergency or not, based on the details of your conversation.
If the veterinarian cannot see the dog immediately, there are a few things you can do to keep your dog comfortable until then.
Aloe Vera Plants can be cut open and the salve rubbed over the dog’s itchy skin for comfort.
Elizabethan Collar will prevent the dog from digging at his skin and making it worse.
Cool air flow around the dog will keep him more comfortable.
Ask the veterinarian before hanging up, what you can do at home to keep your dog comfortable.
Ask a pharmacist what over-the-counter options might be safe for a dog. Benadryl is an antihistamine that has been used on pets to settle allergies. Benadryl will help reduce swelling and ease the dog’s comfort level.
REMEMBER THIS FOR YOUR OWN PEACE OF MIND:
The majority of dogs are treated and regain their health rather quickly. A lot depends on the size of the dog, the dog’s age, and his overall health.
There have only been a few rare cases of death documented and these were dogs who were quite small who had eaten a high number of acorns (upwards of 30 or more).
Being a dog owner is a huge responsibility and it’s nice to see that people care so much.
