Or at the very least, it should not be off-putting. If your puppy’s breath smells really bad there is a chance that it isn’t actually puppy breath but is indeed a different health problem.

What is puppy breath

Puppy breath is a term for the distinctive smelling breath of a puppy’s breath that disappears between about 4 months to 6 months old. This breath is usually sweet smelling, or at least pleasant, in scent.

What causes puppy breath and why do they have it?

There are a couple of reasons why puppy breath occurs. One of the reasons is that the sweet smell is a product of their mother’s milk, which will remain on the puppy’s tongue after feeding.

Another reason is because of the formation and growth of teeth. When teeth rupture the gums it can sometimes produce a smell because of the presentation of clean teeth.

There is also certain bacteria only present in puppies’ mouths which may contribute to the sweet smell. Puppy breath can also be caused by its diet, if you puppy is on a low nutrition diet this can make your puppy’s breath smell.

You can always ask your vet for a nutritional appointment, to make sure your puppy is on the best diet that it can be.

Most common puppy breath smells

Whilst we’ve established that puppy breath can smell different, I’ve compiled a list of the most commonly reported puppy breath smells, and the reasons why they may smell this way.

Some of these smells may be the cause of something more problematic, so don’t just put any smell to being the result of normal puppy breath.

Puppy breath that smells like poop

Unfortunately, this is a common one. However, it is not usually a direct result of puppy breath. It is usually because a puppy has been cleaning its rear end or has consumed some form of faeces. It’s not nice to think about, but it is the way of puppies.

If this smell persists for a long time, then you should book an appointment with your vet as it could be a sign of a dental problem. Dental problems can include plaque build-up and ulcers.

Puppy breath that stinks like skunk

This is also not a pleasant smell and it is usually present in very young puppies, around 8 weeks. Thankfully, this is nothing to worry about and will usually disappear shortly after the 8-week mark.

Skunk breath is caused by digestive enzymes that are only present in very young puppies. It is a normal thing for puppies to have but will fade when the enzymes develop into more permanent digestive strands.

Puppy breath smells like fish

Fishy breath can be the result of teething in a puppy. When their teeth come through it can sometimes push a fishy kind of smell through their gums.

This is usually only during a short period of the puppy breath months. Fishy breath can also occur because sometimes the glands near a puppies anus can produce a fishy kind of smell which will transfer to the puppy’s mouth when they have been cleaning themselves.

Puppy breath smells like coffee

For those who enjoy the smell of puppy breath, a frequent comparison is that puppy breath smells like coffee, but sweeter. Puppy breath that smells like coffee is usually a result of a puppy drinking it’s mothers milk.

The milk from their mother is sweet and the smell persists on the puppy’s breath because the new puppy teeth have not developed any plaque. Plaque has a stronger and more foul-smelling odour which would overpower the coffee smell.

Puppy breath smelling like coffee is not problematic and is actually a strange favourite among dog lovers, owners often missing their puppy’s coffee breath when it has gone.

Puppy breath smells like metal

The main cause of a metallic smell to your puppy’s breath is blood. You don’t need to panic though, it’s quite normal. When puppies are teething, their gums can bleed slightly, similarly to us humans.

This bleeding and teething process can leave these little metallic smelling droplets that linger on your puppies breath. However, if this metallic smell persists after the first few months of your puppy’s life it could be a sign of kidney failure.

The metallic smell in this case would be because of a build up of toxins not filtered properly by the kidneys. If you are worried about the persistence of this smell, remember to book a vet appointment.

Puppy breath smells like rotten meat

Puppy breath smelling like rotten meat is also usually a sign of a health problem, rather than just the standard puppy breath. A rotten meat smell can be a sign of poor dental hygiene.

This can be problematic so make sure to clean your puppy’s teeth, and if the smell persists, book an appointment with your vet. But if you have noticed your dog’s breath smells like urine as well as rotten meat at times, this can be a clear sign of kidney failure.

It is best to book an appointment with a vet to check if anything is wrong with your friend. Particularly if this problem is in an adult dog or older puppy.


Does a puppy’s breath smell when it loses its teeth?

I’ve mentioned before about teething affecting the smell of a puppy’s breath, so let’s look at the effect of tooth loss on puppy breath. When puppies get their adult teeth it can lead to their breath smelling.

As the new teeth push out the old teeth, it may bring up decayed parts of the tooth that previously rested below the gum line. This can cause a fishy smell in your puppy’s breath. Old blood resting under the gums can also cause this smell, so make sure to keep your puppy’s mouth and teeth clean when they are teething.
