Are Cob Nuts Dangerous To Dogs? (Consider This)

There’s something special about sharing a tasty treat with your loyal canine friend. However, as responsible pet parents, we need to ask ourselves if what we’re sharing is safe for them.

A common question that arises is whether cob nuts are dangerous to dogs. AKA hazelnuts…

Let’s dive into this topic and answer the most frequently asked questions around it.

Are Cob Nuts Dangerous to Dogs?

When discussing cob nuts, we’re referring to a type of hazelnut native to the UK.

So, the real question is: are hazelnuts dangerous to dogs?

The short answer is no, they aren’t toxic to dogs. They don’t contain any chemicals or compounds that could harm your pooch.

What owners must be careful of:

While not toxic, this doesn’t mean they’re entirely safe either. Their small, round shape can pose a choking hazard, particularly for smaller dogs.

They could also cause an intestinal blockage if swallowed whole. Therefore, while not toxic, the physical shape and size of cob nuts can present a risk to your pet.

What Happens if a Dog Eats Cob Nuts?

If your dog eats a cob nut, they may be fine, or they could encounter one of several problems.

If the nut is chewed properly and digested well, your dog might not show any signs of discomfort.

On the other hand, if the cob nut is swallowed whole or in large chunks, it could cause gastrointestinal issues.

These could range from mild discomfort and vomiting to more severe conditions like an intestinal blockage, which would require immediate veterinary attention.

Symptoms to look out for include vomiting, loss of appetite, lethargy, and changes in bowel movements.

Can Dogs Digest Cob Nuts?

Dogs can digest cob nuts to a certain degree, but they don’t process them as efficiently as humans do.

Dog’s digestive systems are designed to digest meat more efficiently than plant materials, so while they can technically digest cob nuts, they won’t be getting much nutritional benefit from them.

Moreover, if swallowed whole, the dog’s body may not be able to break down the nut at all, leading to potential blockages.

In essence, while dogs can physically digest cob nuts, they are not an optimal food source for them.

How Many Cob Nuts Can a Dog Eat?

Given the potential risks associated with feeding cob nuts to dogs, it’s best to err on the side of caution.

If you decide to give your dog a cob nut, it should be a very occasional treat and only in small quantities.

Furthermore, always ensure that the nut is crushed or ground up to prevent choking or blockage.

As a general rule of thumb, anything more than a small amount could potentially be harmful.

Always keep a close eye on your dog after they’ve eaten a cob nut to ensure they’re not showing any signs of discomfort.

Are Other Nuts Safe for Dogs?

While we’re on the topic of nuts, it’s worth noting that not all nuts are safe for dogs.

Macadamia nuts and black walnuts, for instance, are highly toxic to dogs and should be avoided at all costs.

Other nuts, like almonds and pecans, can pose a choking hazard and potentially cause blockages in the digestive system, much like cob nuts.

On the other hand, peanuts and cashews are typically safe for dogs when served in moderation and properly prepared (unsalted and not in shells).

However, given the high-fat content of nuts in general, they should be given sparingly to prevent obesity and other health issues.


To summarize, while cob nuts are not inherently toxic to dogs, they do pose potential risks due to their size and shape.

They can cause choking or intestinal blockages if not chewed properly. Also, dogs do not digest nuts as well as humans, and thus, they derive minimal nutritional benefits from them.

If you decide to feed your dog cob nuts, do so sparingly, always monitor them afterwards, and make sure the nuts are crushed or ground up.

As a general rule, it’s always a good idea to consult with your vet before introducing any new food into your dog’s diet.

Remember, not all nuts are safe for dogs; always do your research before sharing any human food with your beloved pet. Keep them safe and healthy by making informed decisions about their diet.
