Can Dogs Chew On Walnut Shells

Dogs can chew on walnut shells, but it’s not something you should encourage.
 
While walnut shells aren’t immediately toxic to dogs, they pose serious risks that make them a poor choice for chewing.
 
If you’ve been wondering whether dogs can chew on walnut shells safely, the answer is that they technically can, but they really shouldn’t.
 
In this post, we’ll explore why dogs might chew on walnut shells, the dangers involved, and what safer alternatives you can offer your furry friend.
 
Let’s dive in.
 

Why Dogs Might Chew on Walnut Shells

Dogs can chew on walnut shells for a few reasons, but none of them are good ones.
 
Understanding why your dog is drawn to walnut shells can help you address the behavior.
 

1. Natural Curiosity

Dogs explore the world with their mouths, so when they find walnut shells on the ground, they may instinctively pick them up.
 
The crunchy texture and interesting shape can make walnut shells seem like a fun toy to chew on.
 
This curiosity is especially common in puppies who are still learning what’s safe to put in their mouths.
 

2. Teething Discomfort

Puppies going through teething often look for hard objects to chew on to relieve gum pain.
 
Walnut shells might seem like a convenient option because they’re hard and readily available.
 
However, their hardness is exactly what makes them dangerous for teething pups.
 

3. Boredom or Anxiety

Dogs who are bored or anxious may chew on anything they can find, including walnut shells.
 
If your dog is routinely chewing on walnut shells or other non-food items, it might be a sign they need more mental stimulation or exercise.
 

The Risks of Letting Dogs Chew on Walnut Shells

Even though dogs can chew on walnut shells, the risks far outweigh any potential benefits.
 
Here’s what you need to watch out for.
 

1. Choking Hazard

Walnut shells are hard and can break into sharp pieces when your dog chews on them.
 
These fragments can easily get lodged in your dog’s throat, causing choking or airway obstruction.
 
Smaller dogs are especially vulnerable because their airways are narrower.
 

2. Intestinal Blockage

If your dog swallows pieces of walnut shells, they can cause serious digestive problems.
 
Walnut shells don’t break down in the digestive tract, so they can create blockages that require surgery to remove.
 
Symptoms of a blockage include vomiting, diarrhea, loss of appetite, and lethargy.
 

3. Damage to Teeth

Walnut shells are much harder than most dog chews, so chewing on them can crack or fracture your dog’s teeth.
 
Dental fractures are painful and often require expensive veterinary treatment.
 
Even if your dog seems to enjoy chewing on walnut shells, the damage to their teeth isn’t worth it.
 

4. Mold and Toxicity Concerns

Walnuts and their shells can grow mold if they’ve been sitting outside for a while.
 
Moldy walnuts may contain mycotoxins, which are toxic to dogs and can cause neurological symptoms like tremors and seizures.
 
This is one of the biggest reasons why you should never let dogs chew on walnut shells.
 

5. Pancreatitis Risk

While the shells themselves don’t contain fat, dogs often find whole walnuts with the nut inside.
 
Walnuts are high in fat, and eating them can trigger pancreatitis in dogs, a painful and potentially life-threatening condition.
 
If your dog chews on walnut shells and accidentally eats the nut inside, they could be at risk.
 

What to Do If Your Dog Chews on Walnut Shells

If you catch your dog chewing on walnut shells, don’t panic.
 
Here’s what you should do.
 

1. Remove the Shells Immediately

Take the walnut shells away from your dog right away.
 
Check their mouth for any pieces that might be stuck between their teeth or in their throat.
 

2. Monitor for Symptoms

Watch your dog closely for the next 24 to 48 hours.
 
Look for signs of choking, vomiting, diarrhea, lethargy, or any unusual behavior.
 
If you notice anything concerning, call your vet immediately.
 

3. Call Your Vet If Needed

If your dog swallowed walnut shells or shows any symptoms of illness, contact your veterinarian or an animal poison control hotline.
 
They can advise you on whether your dog needs to be seen and what treatment might be necessary.
 

Safer Chewing Alternatives for Dogs

Instead of letting dogs chew on walnut shells, offer them safer options that satisfy their urge to chew.
 
Here are some vet-approved alternatives.
 

1. Rubber Chew Toys

Durable rubber toys like Kongs are designed specifically for dogs to chew on safely.
 
You can stuff them with treats or peanut butter to keep your dog entertained for hours.
 

2. Dental Chews

Dental chews are designed to clean your dog’s teeth while satisfying their chewing instinct.
 
Look for products approved by the Veterinary Oral Health Council for the best results.
 

3. Bully Sticks or Antlers

Bully sticks and split antlers are natural chews that are much safer than walnut shells.
 
Just make sure to supervise your dog while they chew and replace them when they get too small.
 

So, Can Dogs Chew on Walnut Shells?

Dogs can chew on walnut shells, but it’s not safe or recommended.
 
Walnut shells pose risks like choking, intestinal blockage, dental damage, and mold toxicity.
 
If you’ve been asking whether dogs can chew on walnut shells, the answer is clear: don’t let them.
 
Stick to safe, vet-approved chews instead, and your dog will stay happy and healthy.
