Why Does This Happen?

Puppies may experience a runny nose for a variety of causes, including:

  1. Congenital defect
  2. Respiratory infection
  3. Allergy
  4. Viral Infections
  5. Pneumonia
  6. Anxiety/Stress
  7. Foreign item

Let’s discuss all these reasons in detail.

  1. Congenital defect

A newborn puppy’s runny nose may result from a congenital condition, such as a cleft palate, which can occasionally be the reason. Cleft palates are uncommon, but when they occur in pups, they can result in various symptoms, including a runny nose, trouble breathing, and an inability to suckle. A puppy must be sent to the vet for therapy as soon as there is a suspicion that the puppy may have a cleft palate.

  1. Respiratory infection

In newborn puppies, a runny nose can be caused by several things, but one of the most prevalent is an upper respiratory infection. This condition manifests much as a cold in people and can be brought on by various viruses or bacteria. A fever, a runny nose, sneezing, and coughing are some of the symptoms seen in a puppy with an upper respiratory infection (URI). If a puppy is sick with a URI, it is essential to keep it warm and comfortable and give it lots of fluids to prevent it from becoming dehydrated. If the puppy has an upper respiratory infection,

  1. Allergy

An allergic reaction is another potential reason a newborn dog may have a runny nose. Puppy allergies can manifest in several ways, including a runny nose, itchy skin, and coughing. It is imperative to take a puppy to the vet for treatment if there is even the slightest possibility that the dog has an allergy.

  1. Viral Infections

An additional typical reason for a runny nose in a young puppy is an illness caused by a virus, such as CDV (Canine distemper virus) or parvovirus. These viruses are highly infectious and may be passed from one puppy to another. They can also be passed from an infected dog to an adult dog. These infections can cause a variety of symptoms, some of which include a stuffy nose, headache, vomiting, and diarrhea. A puppy must be taken to the veterinarian as quickly as possible if there is any reason to think that the puppy has a viral illness.

  1. Pneumonia

If a newborn puppy has a runny nose, it may be an indication that they are suffering from a more serious ailment such as pneumonia. Pneumonia is a severe lung illness that several viruses or bacteria can bring. The signs and symptoms of pneumonia in a puppy are a respiratory infection, coughing, trouble breathing, and a high temperature. It is imperative to take a puppy to the veterinarian as soon as possible for treatment if there is any reason to assume that the puppy has pneumonia.

  1. Anxiety/Stress

It is also conceivable that the newborn puppy’s runny nose results from worry or tension on the owner’s part. This might happen if the puppy is taken away from its mother or put in an unfamiliar setting for the first time. It is crucial to offer a relaxed and positive environment for a puppy that is experiencing stress or anxiety. It is also essential to seek veterinary assistance for the puppy if it is required.

  1. Foreign item

There is also the possibility that a foreign item obstructs the newborn puppy’s nasal passages, which is the source of the dog’s runny nose. It might be anything as basic as a blade of grass or a fragment of food the puppy has managed to get stuck in its nose. A puppy must be taken to the veterinarian as quickly as possible if there is a suspicion that a foreign item obstructs the puppy’s nasal passages. The evacuation of the object will be necessary.

Is a Sniffling Cough in a Young Puppy Likely to Spread an Illness to Other Puppies?

The answer to this question depends on the runny nose root cause.

Aside from those exceptions, a runny nose in puppies is not infectious the vast majority of the time.
