This is not specific to any disease, but indicates that something is either directly upsetting their stomachs, or generally making them feel nauseous. The yellow color is due to bile staining which doesn't tell much other than they are vomiting on an empty stomach. One possibility is that they ate something they were not supposed to like medication, a chemical (i.e. antifreeze), raw meat, or a plant (i.e. lilies). Vomiting is often the first signs of an exposure to a toxin, so I recommend checking if it's possible for them to have eaten anything other than their normal diet. Vomiting and nausea can also be due to an infectious disease, organ failure, or imbalance in the blood. In order to narrow down the possibilities, you would have to take them to the vet for an evaluation. This doesn't appear to be an emergency, but if they are acting very depressed and is vomiting continuously, then it would be best to take them to the vet sooner rather than later. If they are otherwise acting normal, then it's important to not give any food for the next eight hours, but make sure they have plenty of clean water available. If they are not vomiting in eight hours, then only feed a small amount of food (about 1Tbsp.). If they keep that down, then you can feed a little more in two hours. If the vomiting is continuing tomorrow, then it's best to take them to the vet for an evaluation.

If he is eating and seems better than that is a good sign. If, however, he continues to vomit than you need to call your vet and have him examined. He could have a parasite and your vet can test a stool sample for parasites and then prescribe a dewormer, if needed.

Poor Bruno! It could be due to the cold; if he is coughing a lot, that could cause him to vomit. The yellow of his vomit is likely due to bile in his stomach. If Bruno is coughing so hard that he is vomiting, I would take him into the vet tomorrow. He could be very congested, and may need a bronchodilator to help relieve the congestion. In the meantime, you can try using a humidifier or bringing him into the bathroom with the door closed while you take a hot shower - the steam and humidity help to break up congestion and temporarily relieve symptoms associated with respiratory infections.

That depends. If the vomiting continues, then Max should be examined by the veterinarian. Pets can vomit for many reasons and the causes can range from acid reflux to intestinal blockage. Pay close attention to Max’s appetite and attitude. If he does not want to eat or seems like he feels bad, have him examined by the veterinarian. I hope this helps and please feel free to post any additional questions.
