Why acorns are toxic to dogs
When you take your dog for a walk in autumn, there are many things they might ingest that can be dangerous. Acorns that have fallen on the ground can cause poisoning in your dog, so it's important to keep an eye on what they pick up on their walk. Below you'll learn all about acorns, why they're poisonous, and what to do if your dog eats them.
Why are acorns poisonous to dogs?
Acorns contain a substance called tannin, which is found in higher levels in green acorns and less in brown ones. Tannin is a corrosive substance that can cause inflammation of the gastrointestinal tract walls. In some cases, it can also damage a dog's liver and kidneys. As well as the risk of poisoning, there's also a chance acorns could become lodged in the gastrointestinal tract, especially if swallowed whole. In the worst-case scenario, acorn poisoning can be life-threatening for your dog. That's why it's a good idea to keep a close watch on your dog when acorns are falling.
Symptoms of acorn poisoning in dogs
If your dog has ingested acorns, they might experience vomiting and/or diarrhoea. They may also seem lethargic and have a reduced appetite. These symptoms can also be seen in other types of poisoning. However, acorn poisoning can sometimes start with constipation, which may turn into tar-like diarrhoea after a few days.
How many acorns can a dog eat?
The amount of acorns a dog can ingest before becoming poisoned varies. This depends on the dog's size – a small dog could become very unwell from just one acorn if they're unlucky. It’s therefore important to have a rough idea of how many acorns your dog has ingested if you need veterinary help.
See a vet
