Why Do Dogs Throw Up Phlegm?

This very much depends on how often this happens, what the fluid brought up looks like and whether the dog in question is showing any signs of discomfort or illness.

Most dogs will bring up a yellowish, watery fluid from time to time. If the dog is otherwise quite active, eating well and happy, this is probably just bile, caused by acid reflux. The dog will bring it up, often after eating grass, to make himself feel better.

Sometimes this happens because the periods between meals are too long. Changing the feeding regime to three or four smaller meals spread throughout the day, with the last one as late as possible, may help.

Occasionally, a particular ingredient of a food may be the cause. Some dogs react to grain or chicken in this way. Changing foods to something not containing either should then bring improvement.

Another possibility is that the dog has eaten something he should not have and it has made him feel bad. Most of these are minor problems which can be dealt with quite easily.

If none of the above seem to work, or if the dog either refuses to eat or apparently cannot keep his food down when he does, a vet should be consulted immediately, as there may be a more serious problem.

This is also the case if the dog shows any signs of being in pain, becomes altogether listless or reacts aggressive when touched.

Unfortunately, dogs cannot tell anyone how they feel. It is up to the owner to interpret the way their pet behaves and often, in particular with a new pet, this can be difficult.

If there is any doubt that what is happening may not be normal, a vet should be called to ensure the dog's well-being.

Yes, it is normal because occasional vomiting in dogs is not a matter of concern. Dogs can throw up once or twice in a day. This can be due to their feeding habits. Vomiting in dogs is supposed to be due to underlying cause when it occurs at least 3 times in an hour. Occasional vomiting is normal until dogs are eating and playing well.

If dogs vomit consistently then require proper diagnosis and treatment. If vomiting is accompanied by diarrhea and dog show symptoms like loss of weight, loss of appetite, lethargy, weakness etc then serious illness is suspected. So, as your dog is throwing up occasionally then no need to worry. If he has some signs of illness then take him to vet.

The pink tinge is most likely from blood. It could be from the stomach or lungs, but either way your dog should be seen by a vet ASAP. This could a sign of a very serious problem.
