6 Reasons Why Dogs Smell Like Metal

You’re not alone if you’ve ever sensed your dog smelling like metal or iron. And there are so many causes to claim responsibility for that. Not simply because your dog has been digging in places where it shouldn’t.

Dogs may do unusual things, like peeing on their blanket or licking the floor. But smelling like metal is another thing. And these metallic or ionic odors can easily differ from the fishy natural dog odor.

Doggy breath typically has a fishy rather than metallic odor. If your dog is out and about, it’s pretty apparent. And you’re getting that metallic odor from your dog.

My first thought was that maybe your dog was injured. If your dog has a metallic odor, you can ignore the fact as a typical odor. But, it could be an indication of health concerns. 

After all, a metallic odor is frequently connected with blood. It is essential to inspect your dog’s lips for bleeding and to feel for any injuries.

But perhaps blood isn’t the answer. Also, don’t mix up dog stinking and metallic odor. There could be other reasons why your canines smell like metal as well. And, as a dog owner, it may not be enjoyable.

This article has covered some of the most prevalent causes of your dog smelling like metal. Also, we’ve discussed how to prevent and what needs to be done. 

Let’s jump on to the details below:

Reason 1: Dental Issues

Canine periodontal disease or gingivitis is the most common cause of “metallic dog breath.”

Bad breath in dogs is usually characterized by a fishy odor rather than a metallic odor. But, if your dog’s gums are bleeding, his breath may have a coppery, metallic stench. As you can say, the blood has a metallic odor mixed with the breath. 

Check if you are optimistic that the metallic odor is coming from your dog’s breath. And not from his rare part. Then it may be worth inspecting what your dog has chewed or gnawed on.

Check to ensure that whatever the dog has been chewing on hasn’t harmed his oral health. There should be no lacerations or swelling around the gums.


It’s best to act immediately with a vet’s concern. And corrective dental repair is required to avoid significant health issues.

But, if you identify a minor cut in the interdental area. Then you can treat your dog at home and allow it to recover.

Reason 2: Internal body Problem

Metallicity breath can also be caused by internal bodily problems you are unaware of. It can also happen when dogs have gastrointestinal tract problems. You may look for other symptoms, like your dogs pushing food


Suppose your dog has gotten a metallic breath all of a sudden. And something isn’t quite right with his recent actions. Once again, we strongly advise consulting with a veterinarian.

Reason 3: Kidney Disease

Renal disease breath is a common indication of kidney failure. The iron or metallic odor is because of the buildup of waste materials and poisons. 


Again, it would help if you got veterinarian assistance as soon as possible. Because renal failure is fatal if not treated quickly. But try to look for other kidney disease symptoms before heading to a vet. 

Reason 4: Internal Bleeding

As previously said, blood has a distinct odor. It’s typically metallic, especially when new.

Suppose the pup has a severe condition that causes him to bleed into his stomach or respiratory tract. You may notice an iron-like odor on his breath. 

In general, if your dog has a metallic odor. They will also exhibit additional symptoms such as lethargy and despair. 

Though noticing internal bleeding can be a challenging job, as dog owners, we must determine our dogs’ signs. Look for those symptoms to be sure.


Internal bleeding is a matter of concern, and you should immediately take your pet to the clinic. Your vet will examine your dog and adequately treat him. 

Reason 5: Impacted Anal Gland

Because of impacted anal glands, your dog most likely smells like iron or metal. They can become clogged and develop a metallic odor, which some people describe as fishy.

When the pup has a bowel movement, his anal glands usually are emptied. If the anal sacs do not drain or obstruct, your dog will release an iron-like odor.

The fluids within the anal glands thicken over time. Your dog will suffer from both the odor and the pain resulting from this. The longer the impaction goes untreated, the more painful it becomes.


Impaction is cured by expressing or draining the sacs. If the obstruction is severe or if the disease exists. The afflicted sac may need to be flushed to eliminate the hardened substance.

Because these disorders are uncomfortable, some pets will require a tranquilizer or anesthesia for therapy. Visiting the clinic may also be needed.

Your dog’s anal gland may typically recover in a short period. But you can support that with a nutritious diet. Helping your dog lose weight also can be your concern. 

But, if you discover anything suspicious, don’t hesitate to consult a veterinarian.

Your veterinarian may recommend medication and supplements for your dogs.

Some renowned vets recommend these vitamins. That will help with your dog’s nutrition. 

There might be some other reason behind your dog’s metallic smell. 

Reason 6: Scar on Skin

Finally, your dog’s skin may have a scar. Or there is blood on his skin, producing a metal odor. Because, as previously said, the smell of blood is metallic or sarcastic.

Examine his entire body to see whether he has any wounds or scars. 


The most effective approach to halting blood flow is to apply pressure to the wound. This sucks the blood, allowing a clot to develop. Apply a clean cotton pad, gauze, or a feminine hygiene napkin to the bleeding area.

If blood absorbs through the patch, do not replace it if you have any first aid supplies for your dog at home. 

You may try to treat your dog yourself. If the scar is critical, see a veterinarian right away. 


What dog breeds require gland expression?

Certain breeds are more prone to require the manual expression of their glands. They often need this every month. Top of the list is Chihuahuas, Toy and Miniature Poodles, Cocker Spaniels, and Beagles.

What to do if my pup’s glands are infected?

Redness or swelling around the sphincter indicates the glands are infected. The blood or pus in your dog’s stool is also infected, as is the carpet after they’ve completed scooting.
