Kennel cough is so named because the infection can spread quickly among dogs in the close quarters of a kennel or animal shelter. Viral and bacterial causes of canine cough are spread through airborne droplets produced by sneezing and coughing. These agents also spread through contact with contaminated surfaces.
The viral infection can be accompanied by secondary bacterial infections and can eventually present serious neurological symptoms. Canine distemper is caused by a single-stranded RNA virus of the family Paramyxoviridae (the same family of viruses that causes measles, mumps, and bronchiolitis in humans).
Causes include bacterial or viral infection, toxic insult, cancer, copper storage diseases, or it may be idiopathic. [182] Dental disease is very common. Calculus is the most obvious sign, but gingivitis progressing to periodontitis is what results in tooth loss. Treatment involves scaling and polishing of the teeth under general anesthesia and ...
Companion animals such as cats, dogs, and horses, if not vaccinated, can catch serious viral infections. Canine parvovirus 2 is caused by a small DNA virus, and infections are often fatal in pups. [12] The emergence of the parvovirus in the 1970s was the most significant in the history of infectious diseases.
These examples are not considered infectious diseases because they do not satisfy Koch's postulates – for example Staphylococcus intermedius, a commonly isolated bacteria from skin infections in dogs, would not cause pyoderma when introduced to a healthy dog. In all likelihood that type of bacteria is already present on the skin of a healthy ...
A dog with skin irritation and hair loss on its leg caused by demodectic mange. Infectious skin diseases of dogs include contagious and non-contagious infections or infestations. Contagious infections include parasitic, bacterial, fungal and viral skin diseases. One of the most common contagious parasitic skin diseases is Sarcoptic mange (scabies).
Along with age and breed, factors such as a stressful environment, concurrent infections with bacteria, parasites, and canine coronavirus increase a dog's risk of severe infection. [3] Dogs infected with parvovirus usually die from the dehydration it causes or secondary infection rather than the virus itself.
Pneumonia in these dogs is not caused by the influenza virus, but by secondary bacterial infections. The fatality rate of dogs that develop pneumonia secondary to canine influenza can reach 50% if not given proper treatment. [21] Necropsies in dogs that die from the disease have revealed severe hemorrhagic pneumonia and evidence of vasculitis. [22]
