One possible cause for your dog coughing up white foam could be bloat (twisted stomach). For reasons not yet fully understood, the stomach muscles suddenly gets filled with air. It goes on to put pressure on the other organs. The most affected is the diaphragm. This makes it hard for the dog to breathe.
It also contracts veins in the stomach, affecting the heart. The stomach will then twist and turn. The blood supply will be terminated. The most common symptom is that of vomiting. As this is one of the common reasons why dogs cough up white foam, it is important to see a vet as soon as possible.
Usually 30% of those infected die, therefore, treatment is essential. The breeds most susceptible are the Great Dane, Saint Bernard and Poodle.
Another possible reason for throwing up white foam could be a fungal infection. If the dog has a weak immune system, it becomes susceptible to infection. If it tends to lurk or sleep in dirty places, it can end up eating some kind of fungus or bacteria.
Eating Dirty Objects
If the dog vomited only once and seems all right, it could have eaten something dirty. It could have digested small rocks, old food or even grass. The latter has been known to cause dogs to vomit. This is also one of the most common reasons why dogs cough up white foam.
It is also possible that the dog is allergic to the food. It doesn’t always happen, but some breeds just cannot stomach certain dog foods. If they try to eat it, it can lead to indigestion. Those who eat rawhides are also prone to vomiting. You can try changing the food brand.
If the dog stops throwing up, then the food is the source. This doesn’t mean that the dog food brand is of low quality. It’s just that some of them are not compatible with your dog’s system. If you are not sure what to buy, consult your vet.
