Collapsing trachea is a common syndrome in middle-aged and elderly small dogs. In the syndrome, the structures that support the wind pipe, or trachea, weaken. This causes the trachea to narrow during the course of respiration, leading to irritation of the wind pipe and coughing.
Collapsing trachea is a chronic, progressive, and non-curable syndrome. However, it rarely causes severe compromise to quality of life, and very rarely contributes to premature death.
Puppies and kittens. Rarely, adult cats and dogs.
Coccidia are microscopic intestinal parasites of dogs and cats. They are extremely common, but they very rarely cause symptoms in adult animals. In puppies and kittens, they are a frequent cause of diarrhea.
Untreated, severe cases of coccidia in young animals can lead to profuse diarrhea, dehydration, and serious illness. However, most cases of coccidia do not have these consequences.
