If you\u2019re a pet parent, you know the drill. The jolt of panic that comes when you hear your four-legged friend retching. The sigh of exasperation you give upon finding the pile of dog vomit<\/a> they left you. Incredibly gross? Often, yes. Especially when it\u2019s their food. Are you wondering: why is my dog throwing up undigested food? You\u2019ve come to the right place.<\/p>\n\n\n\n

First, let\u2019s get into what else causes dogs to vomit as well as what it means for their longterm health.<\/p>\n\n\n\n

Causes of Dog Vomiting<\/h2>\n\n\n\n

In just one year, the ASPCA Animal Poison Control Center<\/u><\/a> received more than 232,000 calls about pets who ingested toxins ranging from chocolate and plants, to prescription medications. Such ingestion of unauthorized snacks \u2014 also known as dietary indiscretions \u2014 are just one of many reasons dogs vomit.<\/p>\n\n\n\n

Dr. Kendra Scheibe, DVM, notes that motion sickness, parasites, eating too fast, viral infections, and chronic health conditions are also common causes of vomiting.<\/p>\n\n\n\n

In other words, vomit happens. You may not always be able to prevent it. Understanding what causes dogs to throw up can help you determine the best way to help your dog feel better.<\/p>\n\n\n\n

Vomiting vs. regurgitation<\/h3>\n\n\n\n

It\u2019s common for pet parents to use \u201cvomit\u201d as a catchall term to describe any sort of digestive mess. However, it\u2019s important to understand the difference between vomiting and regurgitation. Both involve throwing up, but they are different processes with distinct causes, according to Scheibe.<\/p>\n\n\n\n

Regurgitation<\/strong> often happens when a dog eats too much or too fast; the food goes in and comes right back up. And since the regurgitated food is undigested, it might be tubular in shape just like the esophagus. Regurgitation from eating too fast is the most common reason why dog throw up undigested food.<\/p>\n\n\n\n

There are often no warning signs, like retching, to alert you that your pet is about to regurgitate. \u201cIt\u2019s almost like the dog isn\u2019t expecting it either,\u201d Scheibe explains.<\/p>\n\n\n\n

Regurgitation is rarely a cause for concern. If you notice that your dog regurgitates after eating, Scheibe suggests feeding them smaller, more frequent meals or using a puzzle dish to force them to slow down at mealtimes.<\/p>\n\n\n\n

By comparison, Scheibe calls vomiting<\/strong> \u201can active process\u201d because dogs often show multiple symptoms \u2014 such as salivating, pacing, abdominal contractions, and retching \u2014 that signal they are about to vomit.<\/p>\n\n\n\n

The most common causes of vomiting are many and varied. Your dog might vomit after eating from the trash can, swallowing a sock, or riding in the car. Intestinal parasites, viral infections, and even chronic conditions like diabetes and cancer can also trigger vomiting.<\/p>\n\n\n\n

What Your Dog\u2019s Vomit Is Telling You<\/h2>\n\n\n\n
\"black<\/figure>\n\n\n\n

Though your first reaction to vomiting might be to clean it up as fast as possible, taking a closer look (and sniff) to assess the color, texture, and odor can reveal important clues about potential underlying causes.<\/p>\n\n\n\n

Here\u2019s a quick guide to help you interpret what your dog\u2019s vomit may be telling you:<\/p>\n\n\n\n

Chunky vomit<\/em>: <\/strong>Large chunks of stomach contents could be a sign that your dog ate something unauthorized. The color and texture will vary depending on what they consumed and might even contain telltale signs of evidence. Evidence like bits of fluff from a formerly-stuffed toy, or remnants of a paper plate stolen from the garbage can.<\/p>\n\n\n\n

Dark brown or black vomit<\/em>:<\/strong> These colors aren\u2019t typical for vomit and could be an indication that there\u2019s blood mixed in with the throwup. If you see dark brown or black vomit, it\u2019s time to call the vet, Scheibe says.<\/p>\n\n\n\n

Strong-smelling vomit<\/em>:<\/strong> All vomit has a foul odor, but dogs with canine parvovirus, a contagious virus, produce vomit that has a distinct smell. Vomit with a rancid smell could also be a sign of necrotic tissue and is a reason to call the vet.<\/p>\n\n\n\n

Liquidy yellow or green vomit<\/em>:<\/strong> Small amounts of yellow or green liquid that looks like foam is often bile. That could be an indication that your dog is hungry. \u201cIf your dog is anticipating a meal, their bodies are producing bile in anticipation of being fed. The foam is because they are salivating before throwing up,\u201d Scheibe explains.<\/p>\n\n\n\n

Alternatively, there could be a foreign object stuck in your dog\u2019s stomach and they are trying to throw it up, but only bile is coming out. If this is the case and your dog has a bout of frequent vomiting, watch out for blood in your dog\u2019s bile and take them to the vet. They will need to do an ultrasound or take x-rays to check for a foreign body.<\/p>\n\n\n\n

What to Do When Your Dog Throws Up<\/h2>\n\n\n\n

It\u2019s always a good idea to call the vet when your dog starts vomiting after eating something you know to be toxic or a non-food item. In these cases, Scheibe notes that immediate medical attention is essential to address damage from toxins or possible intestinal blockage.<\/p>\n\n\n\n

Cases of chronic vomiting also require veterinary attention as they may be an underlying condition like pancreatitis<\/a>, megaesophagus, Addison\u2019s disease<\/a>, bloat, or distemper that needs to be addressed.<\/p>\n\n\n\n

Sometimes, a wait-and-see approach may be ok. A dog who wolfs down an all-too-tempting array of table scraps and then starts vomiting might just need time for its stomach to settle after a feast. Withholding food for a bit \u2014 while making sure the dog can access water to stay hydrated \u2014 is often all it takes for your four-legged friend to start feeling better, according to Scheibe.<\/p>\n\n\n\n

Some dogs may try to eat grass after vomiting; it\u2019s ok to let them, assuming the lawn is pesticide-free. \u201cEating grass won\u2019t make vomiting worse,\u201d says Scheibe. \u201cIt\u2019s their way of trying to induce vomiting and it might make them feel better.\u201d<\/p>\n\n\n\n

Dog Vomiting Prevention & Treatment<\/h2>\n\n\n\n

As previously mentioned, you can\u2019t always control dog vomit. But prevention can play a huge role in helping you minimize it. There are several ways pet parents can accomplish that.<\/p>\n\n\n\n

Preventative Healthcare<\/h3>\n\n\n\n

One of the most important things you can do to prevent or limit the amount of dog vomit in your life is to protect your dog from contracting illnesses that can cause vomiting.<\/p>\n\n\n\n

\u201cBe sure to keep your dog up-to-date on vaccinations to prevent parvo and give them monthly preventives for worms and other parasites that can cause vomiting,\u201d Scheibe says.<\/p>\n\n\n\n

Environmental Protection<\/h3>\n\n\n\n

For dogs who are prone to eating from the trash or turning slippers and socks into snacks, a few simple precautions around the home can help your dog avoid digestive system issues. Dog owners should:<\/p>\n\n\n\n
