How much should you worry about your dog’s vomiting and when to see a vet?
Nothing gets an owner moving faster than the sound of their dog heaving. If you’re lucky, you manage to let your dog out in time. Or you might come home from work to a puddle of vomit by the door.
Dogs are built to vomit
Which is a good thing, considering the kinds of stuff they get into. If something doesn’t sit right after it’s gone down, back out, it comes. That is a good thing, particularly when there is an apparent reason you can either think of or discover in the vomit itself.
The signs of impending doom might include your dog drooling, licking their lips (or the furniture, the rugs, themselves), and swallowing excessively. Some seek to eat grass.
If my dog vomits just once, looks and acts normal, and I can put my finger on the cause, I don’t get overly worried.
Throughout their lives, my dogs threw up dead mice, pieces of sticks, rocks, pieces of plastic, a sock (we dodged a bullet there), grass, and horse poop mixed with hay …. Yes, I do worry when I find assorted inedible items in the puke. But as far as I can tell, it all came back out and didn’t cause further trouble.
I don’t encourage my dogs to eat these things, but I can’t watch them every second of every day either.
“Drop it” or “leave it” commands are great if you’re at the right place at the right time. But this had even backfired on me when Cookie discovered that grabbing sticks is a way to acquire more treats. She’d drop one and accept her treat only to turn around and grab another one. Eventually, it turned out that ignoring her stick-grabbing behavior was more successful.
With inedible items, you have to worry about obstructions or perforations.
This was one of the reasons we got pet health insurance. Having a lot of free time outside, it is inevitable that the guys will ingest something inappropriate from time to time. As long as it safely makes its way back out, you’re in the clear.
If your dog keeps vomiting and/or exhibits signs of distress, it’s time to be on your way to the vet.
When to see a vet with your vomiting dog
Signs that you should call your vet include:
- vomiting more than once or twice
- projectile vomiting (a sign of possible gastrointestinal obstruction)
- poor appetite
- diarrhea
- lethargy
- weight loss associated with chronic vomiting, inability to keep food down, or lack of interest in the food
- changes in drinking and urinary habits
- abdominal pain
- abdominal enlargement or distension especially concerning if happening quickly over an hour
- blood in the vomit (partially digested blood looks like coffee grounds; fresh blood is bright red)
- attempting to vomit but nothing comes out
- evidence of poison in the vomit (e.g., packaging or bright green dyes that are included in some types of rat poison)
While there is a serious gross factor involved, examining your dog’s vomit might give you important clues about what’s going on. See the article What’s in the Vomit.
Dogs seem to conduct scientific studies on the edibility of almost everything in their environment. Still, it’s important to remember that their vomiting might have nothing to do with what they recently ate.
Things that can cause your dog’s vomiting
While vomiting is often caused by a problem in the GI tract itself, the issue might be originating somewhere else altogether.
Problems within the GI tract that cause vomiting include:
- dietary indiscretion
- foreign bodies
- intestinal obstruction
- food intolerance/food allergies
- parasites (roundworms, hookworms, Giardia, coccidia, etc.)
- viral infections (canine parvovirus, coronavirus, canine distemper, etc.)
- bacterial infections (Salmonella, E. coli, etc.)
- intussusception (telescoping of the intestines which causes a functional obstruction)
- tumors/growths in the GI tract
- ulcers in the GI tract
Issues outside the GI tract that can cause vomiting include:
- kidney disease/kidney failure
- liver disease/liver failure
- heart disease
- pancreatitis (inflammation of the pancreas)
- pyometra (infection of the uterus)
- severe diabetes mellitus
- Addison’s disease (a disease of the adrenal gland)
- toxins/poisons
- medications
How does your dog feel?
If JD or Cookie vomits something inedible, acts normally, and is hungry, I might not even withhold food and let them eat shortly after. I leave it up to them whether they want to eat or not. Our guys are usually good at making the right judgment about that.
If you pay close attention, your dogs will tell you how ill they feel.
With her IBD, Jasmine threw up fairly frequently. She’d refuse food. Her stomach would make gurgly noises, and eventually, she’d throw up some bile. Shortly after, she’d start feeling better and look for food.
When Cookie got a bout of pancreatitis, she vomited only once, and we were on our way to the vet. Why? Because she was looking sick even before she threw up. She was refusing food and looked tired and lethargic. So when she threw up, we thought that getting it out of her system would make her feel better. But because it didn’t, we didn’t wait any longer.
Know when it’s an emergency
Projectile vomiting, repeatedly vomiting, trying to vomit but nothing coming out, blood (whether fresh or digested) … mean you need to see a vet ASAP.
A vomiting dog who is lethargic, weak, shaking or otherwise obviously in distress, needs to see a vet immediately.
With severe vomiting, your problem isn’t only the underlying cause but also the dehydration, acid-base imbalances, and electrolyte disturbances caused by the vomiting.
Waiting too long before seeing a vet could even be fatal.
