A dog who is coughing up white froth can be suffering from a number of medical issues. White froth does not always mean there is a serious problem, but repeated coughing of white froth should be checked by a vet.

Bloat

Bloat is a serious medical condition that occurs when too much air gets into the abdominal cavity of a dog. Coughing up white foam can be a symptom of bloat and should be checked out immediately as it can be fatal.

Infection

Fungal infections can cause a dog to cough up a white frothy liquid. A dog might pick up a fungal infection from eating something containing fungus or bacteria.

Excitement

Some dogs cough up white froth simply because they are overexcited. For dogs who are prone to this, refraining from getting them worked up can help tremendously.

Hormones

Pregnant dogs might cough up white froth due to a change in their hormone levels. While it is not something to worry about, repeated coughing should be investigated further.

Kennel Cough

Kennel cough, or Bordatella, can cause a dog to cough up a white foam. Dogs who live in shelters, or have recently been boarded are most likely to suffer from kennel cough.

Tonsillitis

Tonsillitis can often cause a dog to cough up a white froth. Tonsillitis is more common in small dog breeds than large ones, and can be treated with a course of antibiotics.
