My senior dog vomits green liquid and drools daily. Is it serious?

Updated on September 23, 2025

Pet's info: Dog | Mixed Breed | Female | spayed | 85 lbs

My 13 year loud dog was on pain pills for arthritis for about 2 months. She started vomiting, so the vet took her off of them. But for the last 3 month's she vomits 1 to 2 times a day slimmy greenish stomach acid with really thick drool. I'm not sure if it could be a more serious illness that I'm not aware of, she is eating, drinking and going to the bathroom just fine. should I have a blood panel done?

It is not normal for a dog to vomit every day. You really need to take Storm back to your vet for an exam of the gastro-intestinal tract, which will include bloodwork as well as possibly and ultrasound or xrays. She may have a stomach ulcer, tumor or chronic gastritis or other intestinal or gastric problem and that needs to be investigated.

Poor Eli! I would recommend to talk with your veterinarian about next steps. Some of these dogs will respond to a special diet for possible inflammatory bowel disease. Some of these pets can have parasites that need to be addressed. Many of these dogs will go on to have an abdominal ultrasound to look for any signs of a tumor or other abnormalities. Some pets will even go on for an endoscope with biopsies. Best to consult your vet about what next steps make the most sense for Eli. I hope this helps to point you in the right direction. Please feel free to post any additional questions!

Unfortunately diarrhea can be a sign of many different diseases, and since Misty has not responded to the initial treatment I'd recommend rechecking with your veterinarian. Liver disease, pancreatitis, food sensitivity, Addison's disease, and inflammatory bowel disease are just a few of the many diseases that can cause recurrent diarrhea and vomiting. Your veterinarian might recommend checking a blood panel as the next step.

I would recommend having Misty evaluated by her veterinarian. And intermittent vomiting and diarrhea is not a normal part of old age and should not last several weeks. Vomiting and diarrhea can be caused by tocsin ingestion, parasites, pancreatitis or G.I. disease, or some endocrine disorders. Her vet will perform a physical exam and then discuss possible diagnostic testing they may recommend depending on exam findings. Many conditions are still easily treatable even in older dogs so I recommend getting misty checked soon to get her feeling better. Thank you for using Petco Pet Education Center, formerly Petcoach.

My senior dog is vomiting whole food. Is it serious if she's normal?

If this is a new, sudden behavior, it's a good idea to have Jazmine examined by your vet, especially since she is a senior girl. Sudden symptoms like this could indicate an underlying illness, something obstructing the GI tract, or even changes to the tract itself affecting motility. If she is gulping her food down, feeding smaller meals more often may help prevent her from throwing it all back up as well.

My senior dog vomits often but has good energy and appetite. Why?

Vomiting that often in an older dog that still has an appetite and is drinking water can be a sign of something stuck in the stomach or a mass. If Kruzer ate a ball, toy bone or something in the yard it may not be able to pass and may sit in the stomach causing irritation and vomiting. As this has been going on for a few weeks I recommend taking him in for abdominal X-rays. They should be able to see if the stomach is normal and if there is anything stuck in it. If he's losing weight and not feeling well then I would run a blood panel also to check his organ function. Once they have a diagnosis of the cause of the vomiting they can then proceed with treatment. If he has something stuck in the stomach sometimes surgery is needed to remove it. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Kruzer.

Chronic vomiting is always a good reason for concern, it could be a sign of an internal disease such as a tumour, kidney failure or pancreatitis among other things, you should take Wolfie to the vet in order to get it checked, he will need to have a blood test done so the vet can gather some more information.

My senior dog vomited, now she's weak and slow. Should I worry?

At her age, we definitely want to take changes like this seriously. If she's eating and drinking, breathing 10-30 breaths per minute while resting, able to get up and move around, and has normal pink gums, it doesn't sound like an emergency, but I would recommend a vet visit in the next few days if she doesn't go back to normal.

My senior dog is drooling a lot. What does it mean and is it serious?

Too much drool, or hypersalivation, can be a sign of illness. Here are some causes: Heat stroke and heat exhaustion, nausea and anxiety can cause episodes of drooling. Mouth disease and tooth decay: Tarter buildup can rub against the inside of your dog’s lip, causing drool. To check, pull his lip back toward his ear. Do his teeth look like concrete? Are they brown? Are his gums red, swollen, or bleeding? If so, try a professional cleaning and then daily brushing. Your vet can check for gingivitis, mouth ulcers, and tumors as well. Organ disease: Liver and kidney diseases, for example, can cause drooling. As they age, dogs are more likely to get sick. Vets suggest annual checkups to diagnose and treat diseases early. Poisonous plants: Common plants like tulips, azaleas, and chrysanthemums can not only make your dog drool, but also make him sick. Keep your dog from eating them. For a list of poisonous plants, consult the American Society for the Prevention of Cruelty to Animals (ASPCA). Stomachaches: Dogs don’t tend to think before eating. Vets report pulling some strange items from their stomachs, from tennis balls to socket wrenches. This can cause nausea, discomfort and pain. Keep dangerous items away from him. Upper respiratory infections: Drooling can signal an infection of the nose, throat, or sinuses. Dogs that live in homes or shelters with other pets have a higher risk. Stress is also a factor. Only your vet can properly treat an infection. But you can take steps to protect your dog: Keep him indoors, away from other pets, and wash your hands between handling different animals. You’re the best judge of your dog’s behavior. If he’s acting strange for more than a day, he seems stressed, or he is not eating and playing as usual, it’s wise to see a vet.

My dog threw up green. Is green vomit dangerous and what to do?

There may be vegetable bits inside and any food that could turn the stomach content into green color. Such a liquid and profuse vomiting is quite concerning, A clinical examination at your local veterinarian is immediately essential to confirm these clinical suspicions and treat appropriately. Antibiotics and possibly further investigations (like abdominal imaging as ultrasound or radiographs) may be needed.

My dog has green mushy poop, mucus, and vomiting. What can I do?

I'm sorry to hear that Stinky isn't feeling well. I can't tell if the soft stool are vomiting are common for her or a new thing. If long term (more than a month), it could be caused by intestinal parasites, food intolerance or allergy, or less likely an endocrine issue. If it's a sudden change, she could have caused an acute entrogastritis by eating something different/bad, could have an infection, or many other causes. If she's eating well and energetic, it's not generally an emergency and you can wait to see if she gets better with time. A daily probiotic can help (anything you find at a store is fine, or you can buy Fortiflora on Amazon). If the vomiting has been going on for more than a few days, or is frequent (more than a couple times a day) I would recommend a vet visit when possible
