CIRD in Dogs: What You Need to Know About Infectious Diseases

CIRD in dogs can be a real challenge for pet owners. Canine Infectious Respiratory Disease (CIRD) is a complex condition that affects a dog's respiratory system, making it difficult for them to breathe.

CIRD is highly contagious and can be spread quickly through dog-to-dog contact, even if the dogs are not showing symptoms. This means that if your dog has CIRD, it's essential to keep them isolated from other dogs until they've fully recovered.

Symptoms of CIRD can vary from dog to dog, but common signs include coughing, sneezing, and difficulty breathing. In severe cases, dogs may even develop pneumonia.

Fortunately, with proper treatment and care, most dogs can recover from CIRD.

Infectious disease in dogs is a serious health issue that affects many canine populations. It's caused by various pathogens, including viruses and bacteria.

One of the most common causes of CIRDC is the canine parainfluenza virus (CPIV). Vaccines are available for CPIV, but they don't provide sterilizing immunity, only reducing the severity of clinical signs.

Vaccines are available for many common CIRDC pathogens, including CAV-2, CDV, CPIV, CIV H3N8, and H3N2, and B bronchiseptica. With the exception of CDV, these vaccines decrease the severity of clinical signs and the magnitude of pathogen shedding.

The CDV vaccine is a core vaccine that should be administered to all dogs. It's the only vaccine that provides sterilizing immunity against a CIRDC pathogen.

Intranasal and parenteral vaccines are available for CPIV, CAV-2, and B bronchiseptica. Intranasal vaccination may provide greater clinical protection against challenge than oral vaccination.

A culture can be taken of the dog's upper airway to diagnose the underlying cause of CIRDC. However, this typically requires sedation and only covers bacteria.

Polymerase chain reaction (PCR) tests can be used to diagnose CIRDC by detecting genetic material of the underlying cause. These tests don't require sedation and are relatively affordable.

Kennel cough is a contagious respiratory disease that affects dogs, and understanding its causes and transmission is crucial for prevention and treatment.

Bordetella bronchiseptica and Parainfluenza are the most common causes of kennel cough in dogs, according to veterinary reports.

Kennel cough can be caused by a variety of pathogens, including bacteria and viruses. These pathogens can weaken a dog's immune system, making them more susceptible to infection.

The list of causative agents for kennel cough is long and growing, including bacteria like Bordetella, Streptococcus, Mycoplasma, and Chlamydia, as well as viruses like Canine Parainfluenza, Canine Influenza, and Canine Adenovirus type 2.

Direct dog-to-dog contact is the obvious route of transmission for kennel cough, but it can also be spread through contaminated surfaces and aerosols.

Some common situations that can put your dog at increased risk for kennel cough include dog park visits, vet visits, grooming, day care, boarding, multi-dog households, training classes, daily walks or contact with other dogs, chronic heart or lung disease, compromised immune system, commercial transport, recent adoption from shelter or rescue, and pet store visits.

Here are some common situations that can put your dog at increased risk for kennel cough:

Even you, as a dog parent, can contribute to spreading the disease if you come in contact with an infected dog and then pet your own.

Most vets can diagnose canine cough, also known as CIRD, based on the patient's history and clinical symptoms. A thorough physical examination is performed, and a chest x-ray is often taken to rule out pneumonia.

If your dog is showing mild clinical signs, such as a persistent cough, and has been bright with a good appetite for less than a week, no specific therapy is recommended. However, if clinical signs persist beyond 1 week or any signs of bacterial pneumonia are present, treatment with antimicrobials is necessary.

In many cases, treatment involves supportive care, such as hydration, nutritional support, oxygen therapy, nebulization, and coupage, tailored to the patient's need. Antibiotics, such as doxycycline, may be prescribed if a bacterial infection is suspected, and cough suppressants can be used to provide relief, but their use is still somewhat controversial.

Diagnosis is a crucial step in treating canine cough. A thorough physical examination is usually performed by a vet to assess the patient's condition.

Most vets can diagnose canine cough based on the patient's history and clinical symptoms. The vet will ask about the dog's vaccination history, exposure to other dogs, and any recent travel to determine the likelihood of kennel cough.

A chest x-ray is often performed to rule out pneumonia, which changes the course of treatment and affects the outcome.

Treatment for kennel cough is often debated among veterinarians, but it's generally recommended to let mild cases run their course.

Antibiotics are traditionally used to treat kennel cough, but they're only effective against bacterial infections, not viruses.

Doxycycline is a common antibiotic used to treat kennel cough, especially in cases where bacterial infections are suspected.

However, antibiotics may prolong the infection if used too early, so it's essential to wait a few days before starting treatment.

In severe cases, antibiotics can prevent secondary bacterial infections and shorten the shedding period, making them a crucial part of treatment.

Cough suppressants can make a dog feel more comfortable, but they may also prolong the time needed to clear up the infection.

Nebulization with sterile saline can help keep the dog's airway moist, which can be beneficial in reducing symptoms.

Most dogs will clear the infection on their own within 10 to 14 days, but it's essential to keep them away from other dogs during this time to prevent the spread of the infection.

Antibiotics can shorten the shedding period, making them a crucial part of treatment in kennel cough cases, especially in shelters where the spread of the infection needs to be controlled.

When dealing with canine infectious respiratory disease complex (CIRDC), it's essential to understand the primary pathogens involved. According to Table 1, the main culprits are B bronchiseptica, Mycoplasma cynos, Streptococcus equi subsp zooepidemicus, Canine adenovirus 2, Canine distemper virus, Canine herpesvirus-1, Canine influenza virus, Canine parainfluenza virus, and Canine respiratory coronavirus.

B bronchiseptica has an incubation period of 2-6 days and can cause variable symptoms, ranging from commensal to severe bronchopneumonia. The vaccine for B bronchiseptica is available in parenteral inactivated and attenuated live intranasal, mucosal forms.

Mycoplasma cynos has an incubation period of 3-10 days, and its clinical syndrome is not completely described, although it's been isolated from dogs with pneumonia. Unfortunately, no vaccine is available for Mycoplasma cynos.

Streptococcus equi subsp zooepidemicus has a probable incubation period of days and can cause mild upper-respiratory signs or subclinical infections. However, it can also lead to severe, rapidly progressing hemorrhagic pneumonia in overcrowded environments.

Canine adenovirus 2 has an incubation period of 3-6 days and typically causes mild upper-respiratory signs and a harsh cough that lasts for 2 weeks. The vaccine for Canine adenovirus 2 is available in attenuated live parenteral and mucosal forms, offering cross-protection for Canine adenovirus 1.

Here's a breakdown of the primary pathogens associated with CIRDC:

Vaccination is a major prevention strategy for Canine Infectious Respiratory Disease Complex (CIRDC).

Vaccines are available for many common CIRDC pathogens, including CAV-2, CDV, CPIV, CIV H3N8, and H3N2, and B bronchiseptica.

The CDV vaccine is a core vaccine that should be administered to all dogs.

Intranasal or intraoral vaccination can sometimes result in vaccine-induced disease, and it can be difficult to know whether disease in a shelter environment is secondary to the vaccine or natural infection.

Parenteral vaccines are available for reduction of clinical signs owing to CIVs, including individual H3N8 or H3N2 vaccines and combination (bivalent) vaccines.

Vaccination does not protect against all infections, so additional precautions must be taken in group-housing situations, such as an isolation period for dogs entering the population and rigorous daily monitoring for development of clinical signs.

Care should be taken to prevent overcrowding and stress within the population.

For otherwise healthy and regularly vaccinated dogs, the prognosis is excellent.

The prognosis is good to excellent even for dogs that developed pneumonia, as long as appropriate treatment was timely initiated.

Dogs with pre-existing respiratory diseases, brachycephalic dogs, puppies, geriatric dogs, and immune compromised pets have a poorer prognosis.

Most dogs don't even require treatment and recover on their own within 10 days, but dogs with concurrent respiratory disease, brachycephalic breeds, and weak immune systems have a poorer prognosis.

Dogs vaccinated for the CIRD pathogens have a much better prognosis, and vaccination can dramatically reduce the duration and severity of disease.

CIRD in dogs can manifest in various ways, depending on the underlying cause.

In some cases, CIRD can lead to chronic coughing, which may persist even after treatment.

Dogs with CIRD are also more prone to developing secondary infections, such as pneumonia.

A common symptom of CIRD is a persistent, dry cough that can be heard by veterinarians during an examination.

CIRD can be caused by a variety of factors, including viral infections, such as canine adenovirus and parainfluenza virus.

Bordetella bronchiseptica is a bacterial pathogen associated with canine infectious respiratory disease (CIRDC), and vaccines are available to decrease the severity of clinical signs.

Vaccination with intranasal vaccines against B bronchiseptica can result in low titers of serum immunoglobulin G (IgG) compared to parenteral vaccination.

Mycoplasma cynos is a fastidious organism that lacks a cell wall and is associated with respiratory disease in dogs, most commonly pneumonia.

M cynos can persist in the lung for up to 3 weeks following infection and be transmitted via aerosols.

While other Mycoplasma spp can survive for several weeks outside of the host, it's unknown how long M cynos can persist in the environment.

Bacterial organisms like B bronchiseptica and M cynos can be challenging to diagnose due to the need for specific testing and the potential for coinfections.

If you suspect your dog has a bacterial infection, consult with your veterinarian to determine the best course of action and treatment.

The scientific name for kennel cough is actually a bit of a misnomer, as it's not exclusively found in kennels anymore. In fact, kennels were once the most densely populated places for dogs, which is why the term "kennel cough" stuck.

Canine infectious tracheobronchitis or canine infectious respiratory disease (CIRD) is the preferred term used by veterinary scientists. This name accurately reflects the condition's widespread nature and its impact on a dog's respiratory system.

In the past, kennels were indeed the hotbeds of this disease, but today you can find large numbers of dogs in various places, making the term "kennel cough" less fitting. This is why some people are starting to use the term "canine cough" instead.

Symptoms of cird in dogs can be quite distressing for both the dog and its owner. A dog with cird will usually show symptoms such as a dry or productive cough, often with foamy mucus.

Retching or gagging, watery discharge from the nose, and runny eyes are also common symptoms. The first few days are often the worst, as bouts of hacking cough can be triggered by barking, excitement, pulling on the lead, and going out in cold air.

To alleviate the symptoms, it's essential to provide a well-ventilated but warm and stress-free environment for the dog. This can be achieved by keeping the dog indoors, away from other dogs, and providing a comfortable place to rest.

Home remedies such as using nebulizers with saline water twice a day for at least 10 minutes, offering softer foods, and using a harness instead of a collar can also help. However, it's crucial to discuss any home remedies with a trusted vet prior to use, and after a veterinary examination first.

Here are some specific actions you can take to help your dog feel better:

A dog with kennel cough will usually show some or all of the following symptoms: dry or productive cough, often with foamy mucus, retching or gagging, watery discharge from the nose, and runny eyes.

These symptoms can be triggered by various factors, such as barking, excitement, pulling on the lead, and going out in cold air.

The first few days are often the worst, with bouts of hacking cough being triggered by even the slightest provocation.

Here are some common triggers to watch out for:

Home Remedies can be a big help in alleviating your dog's kennel cough symptoms. Certain remedies can be used to soothe the throat and calm the cough.

Honey is one such remedy that can be used to help soothe your dog's throat. However, it's essential to discuss its use with your trusted vet before administering it to your dog.

Robitussin and cough syrups can also be used to alleviate the cough, but their use should also be discussed with your vet prior to use.

To help keep your dog's throat moist, nebulizers with saline water can be used twice a day for at least 10 minutes. This can be a big help in reducing the severity of the cough.

Here are some additional tips to help your dog feel more comfortable while recovering from kennel cough:

Kennel cough sounds like a honking goose, with a forceful, persistent, harsh, and hacking cough that can be dry or produce white foamy saliva.

The cough can be so severe that it's like there's something lodged inside the dog's throat, making it sound like they're choking and about to bring something up, but nothing comes.

It's a dry, hacking cough that can be unsettling to hear, and it's often described by pet parents as sounding like a goose.
