Why did my dog threw up after eating bacon?

It can be concerning and alarming when your dog vomits after eating something new. Bacon is a common culprit that can cause an upset stomach in dogs. There are a few reasons why bacon may lead to vomiting in dogs.

High Fat Content

One of the main reasons bacon can cause vomiting is that it has a very high fat content. The average slice of fried bacon contains around 5 grams of fat, with 43% of those calories coming from fat. Dogs are not as efficient at digesting fat as humans are. When a dog eats a high amount of fat at once, it can overwhelm their digestive system and lead to an upset stomach. Their stomach and pancreas produce more lipase and bile to break down the fats, which can irritate the stomach lining and cause nausea and vomiting.

Some dogs may be more sensitive to dietary fat than others. Obese dogs and smaller breeds are more prone to gastrointestinal upset from high-fat foods. The high fat levels in bacon are a common trigger for vomiting and diarrhea in dogs. Slowly introducing high-fat foods and avoiding large portions can help prevent an upset stomach.

Salt Content

In addition to fat, bacon contains a large amount of sodium. A regular slice of pan fried bacon contains around 188 milligrams of sodium. Eating multiple pieces of bacon can quickly add up in sodium amounts. Too much salt at once can cause dehydration and electrolyte imbalances in dogs, which leads to vomiting and diarrhea.

Sodium helps retain water in the body. When a dog rapidly consumes a large amount of salt, it can cause water to be pulled to the intestines to dilute the salt. This shifts the fluid balance and causes inflammation in the intestinal tract, which creates an upset stomach. Dogs that are not used to high salt levels are most likely to be affected by the sodium content in bacon.

Preservatives& Nitrates

Many types of bacon contain preservatives like nitrites and nitrates to maintain color and extend shelf life. While these additives are considered safe in small amounts, large ingestions can be toxic and irritating to a dog’s stomach. The preservatives get converted to nitrosamines during digestion, which can cause oxidative damage to the stomach and intestines. This gastrointestinal irritation stimulates vomiting reflexes.

Some dogs may also have sensitivities or allergies to specific preservatives used in bacon. Reactions to sodium nitrite or sodium erythorbate found in cured bacon products can lead to vomiting, diarrhea, wheezing, and skin reactions in sensitive dogs. Checking ingredient labels and choosing preservative-free bacon can help avoid adverse reactions.

Foreign Food& Richness

Since bacon is a fatty, salty, rich meat that dogs are not used to eating regularly, it can come as a shock to their digestive system. Any new, foreign, or rich human food can disrupt a dog’s normal digestive balance and cause stomach upset.

While small amounts of new foods are usually tolerated, large portions or whole meals of people food items like bacon overwhelm a dog’s stomach. The richness, spices, and unfamiliar ingredients are hard to digest, which leads to vomiting and diarrhea. Introducing new foods slowly in tiny pieces helps avoid overwhelming their digestive system.

Speed of Eating

Many dogs will gobble up bacon quickly because of its desirable smell and taste. Eating too fast does not allow enough time for proper chewing and digestion. Large pieces of bacon can get lodged in the esophagus, stomach, or intestines, causing irritation, nausea, and vomiting.

Slow down your dog’s eating by hand feeding bacon in tiny pieces. You can also mix it into their regular food to encourage slower consumption. Avoid giving your dog large hunks of bacon which they are likely to swallow whole. Proper chewing and digestion is key to avoiding indigestion.


One of the most dangerous risks of feeding bacon to dogs is pancreatitis. The high fat content in bacon can trigger a painful inflammatory condition called pancreatitis where the pancreas becomes swollen and stops functioning properly.

The pancreas produces enzymes for fat digestion. High dietary fat stimulates the pancreas to go into overdrive producing these fat-splitting enzymes, which causes inflammation and organ damage. Pancreatitis can cause severe vomiting, abdominal pain, bloody stool, diarrhea, and even death in dogs. It requires intensive veterinary treatment with IV fluids, pain medication, and a low-fat diet.

Obese dogs, Schnauzers, Shelties, and Terriers are most at risk for developing pancreatitis from fatty foods like bacon. While a single piece likely will not cause pancreatitis on its own, regular feeding of fatty foods greatly increases a dog’s risk of developing this serious condition.

Is Bacon Safe for Dogs at All?

While bacon does come with some risks and may cause stomach upset, it does not need to be completely avoided in dogs. The key is feeding only small amounts on occasion. Here are some tips for safely feeding bacon to your dog:

– Choose uncured bacon without nitrates or nitrites. This avoids excess sodium and preservative-related irritation.

– Look for bacon made from pork, turkey, or beef to avoid reactions to alternate proteins.

– Cook bacon fully until crispy to render off some fat; avoid giving raw bacon or fatty trimmings.

– Feed only 1-2 small pieces of bacon maximum per treat. Too much can overwhelm their digestion.

– Cut bacon into small bite-sized bits. This prevents your dog from swallowing large chunks whole.

– Introduce slowly over the course of a few days by giving just tiny bacon morsels at first.

– Mix bacon bits into their regular dog food instead of giving bacon alone.

– Avoid additional high-fat foods on days when your dog gets bacon to prevent pancreatitis risks.

– Watch for any signs of stomach upset like vomiting, diarrhea, or lack of appetite after eating bacon.

As long as proper precautions are taken, most healthy dogs can enjoy a few pieces of bacon per week without issues. Monitor your dog closely and ask your veterinarian for input on an appropriate bacon feeding schedule for your pup.

What to Do If Your Dog Vomits After Eating Bacon

If your dog becomes sick after eating bacon, here are some important steps to take:

– Withhold food for 12-24 hours to give their stomach time to rest and settle. Provide small amounts of water.

– Monitor for weakness, lethargy, blood in vomit or stool, fever, lack of appetite, or tenderness in the abdomen, which indicates a more serious issue.

– Avoid giving any fatty foods during this fasting period to allow the GI tract to recover. Stick with a bland diet once feeding resumes.

– Call your vet if vomiting persists beyond 24 hours or additional symptoms develop. Your dog may need medications or IV fluids for dehydration.

– Discuss a more gradual bacon introduction or avoidance if it consistently causes vomiting. Some dogs have true allergies or intolerances.

– Consider baseline bloodwork if your dog has recurring vomiting to rule out pancreatitis and other serious conditions.

– Look for natural dog anti-nausea products containing ginger, mint, fennel, or chlorophyll to soothe their upset stomach.

With some rest and TLC, your dog should recover after a single bacon-related vomiting episode. But if symptoms persist or seem severe, get veterinary attention right away. Be cautious about reintroducing bacon to avoid repeat issues.

How to Prevent Vomiting When Feeding Bacon

You can reduce the likelihood of vomiting by taking these precautions when giving bacon to dogs:

– Choose uncured bacon without nitrates, nitrites, erythorbate or other preservatives.

– Look for reduced-fat or turkey bacon to cut down on high amounts of fat.

– Cook until crispy to decrease fat content before feeding.

– Cut bacon into tiny pieces to prevent choking hazards.

– Introduce slowly over days by giving just a few crumbs at first.

– Avoid feeding the fatty bacon trimmings and sticks to the stomach lining.

– Feed just 1-2 small pieces maximum at a time.

– Spread out feedings to avoid eating too much fat in one sitting.

– Mix into their existing dog food instead of offering bacon alone.

– Ensure your dog chews thoroughly and eats slowly.

– Know signs of pancreatitis and stop feeding bacon immediately if these appear.

– Ask your vet if your dog has any individual risk factors before feeding bacon.

With some smart precautions, you can allow your dog an occasional bacon treat in a safe way. But it’s always a good idea to check with your vet on diet advice tailored specifically for your dog.

Frequently Asked Questions

Why is my dog throwing up yellow bile after eating bacon?

Throwing up yellow foam or fluid after eating bacon likely means your dog’s stomach is irritated and inflamed from digesting such a fatty meal. Their stomach secretes excess mucus and bile, which comes back up as yellow vomit. Give their GI tract a rest by withholding food for 12-24 hours and avoid fatty foods for a few days. Seek veterinary care if vomiting persists.

Is bacon grease safe for dogs?

No, bacon grease is too high in fat and can cause pancreatitis. Dogs should not consume the leftover grease or any bacon drippings. Stick to small, fully cooked pieces of bacon only, and do not give any raw bacon fat trimmings.

Can puppies eat bacon?

You should avoid feeding bacon to puppies under 1 year old. The high fat and sodium content can create digestive upset in puppies who have a developing immune system and GI tract. Wait until maturity to introduce small bacon bits mixed into their regular puppy food.

How much bacon can I give my dog?

No more than 1-2 small pieces of fully cooked bacon 1-2 times per week. Too much bacon can lead to vomiting, diarrhea, and pancreatitis. Introduce slowly in small amounts. Also avoid additional fatty foods on the days you provide bacon treats.

Why does my dog keep throwing up undigested bacon?

If you notice whole chunks of undigested bacon coming back up, your dog likely ate the bacon too quickly without proper chewing. It was then regurgitated before having time to digest. Slow down your dog’s eating and cut bacon into tiny bites to prevent indigestion and vomiting.


While delicious and appealing to dogs, bacon does come with some risks of gastrointestinal upset and pancreatitis. By feeding only small portion sizes on occasion and taking preventative measures, you can allow your dog to enjoy a bacon treat safely as part of a balanced diet. Monitor for any vomiting or diarrhea, and ask your vet if you have concerns over your dog’s tolerance to fatty foods like bacon. With some caution, your dog can get a taste of this tasty treat!
