The Impact of Antibiotics on Dogs
Antibiotics serve a divine purpose for our four-legged friends: to fight off infection and keep sickness at bay. With their help, dogs can recover more quickly from illness and lead healthier lives. But thereâs one flaw with antibiotics thatâs pretty hard to overlook:
Antibiotics destroy your dog's gut health.
Think of antibiotics as if they were microscopic military drones, and their assigned mission was to enter the battlefield that is your dogâs body. To ward off potential infection, these drones are programmed to seek and destroy all bacteria in their path.
The problem, of course, is that these drones (antibiotics) have no way of distinguishing between âgoodâ and âbadâ bacteria, so to be safe, they destroy all bacteria in sight. And while this may be a very efficient way to stop infection in its tracks, this action can wreak havoc on your dogâs digestive health.
Consequences of Antibiotics On Gut Health and How Probiotics Can Help
As an antibiotic makes its way through your dogâs body, it leaves a path of destruction in its wake. The delicate microbiota of your dogâs gut is discombobulated, which can lead to all kinds of secondary problems.
Letâs take a closer look at the consequences of antibiotics on a dogâs gut health.
Gut Health
It's wild to think about, but your dogâs intestines are home to a whole ecosystem of bacteria and microorganisms. This community is often referred to as the gut microbiome, and they play a vital role in digestion, immune system function, and overall health.
As with most ecosystems, the gut microbiome is incredibly delicate and very sensitive to any sort of change. So when an aggressive agent (like an antibiotic) comes into town, it can quickly throw the whole system into turmoil, leaving your pet to suffer the consequences.
When your dogâs gut microbiome is out of balance, he may experience any one of the following symptoms:

Fortunately, thereâs a hero lurking in the background who will soon join our story: Probiotics.
But before we get into all that, letâs talk a little bit more about the effect of antibiotics on your dogâs bowel movements, and what signs to look for when you suspect somethingâs not quite right.
Antibiotic-Associated Diarrhea
As weâve stated before on this blog, much of what we know about pet health stems from research involving humans. So letâs take a look at what science has to tell us about antibiotic-associated diarrhea.
According to the Mayo Clinic, approximately 1 in 5 people who take antibiotics will develop antibiotic-associated diarrhea. Research indicates that this is likely caused by disruption of the intestinal flora in response to the presence of an antibiotic.
The subjects of the aforementioned study indicated that diarrhea occurred within just one week of taking an antibiotic though, fortunately, most cases cleared up on their own without warranting further treatment.
Antibiotic-associated diarrhea can happen to anyone, but itâs much more likely to occur in those who:
So what does this mean for your pet? Well, if your pup is taking antibiotics and they suddenly start having loose stools or diarrhea, itâs probably related!
Weak Immune System
As you can see, antibiotics can have a pretty negative impact on a dogâs gut health, but thatâs not the only system that will suffer the consequences of this attack!
Antibiotics can also cause serious damage to your dogâs immune system.
How, you might ask? Well, let us break it down for you.
As weâve learned, when antibiotics enter the body, they donât just target the âbadâ bacteria causing infection - they also kill the âgoodâ bacteria that help keep your dogâs immune system functioning in tip-top shape.
These âgoodâ bacteria serve a lot of different purposes; one of which is to act as a protective barrier for your dogâs gut, preventing harmful microbes from taking over and making your pup sick.

But when antibiotics show up and wipe them out, your dogâs immune system is left just as vulnerable as a young kid without his safety blanket.
Infections
Additionally, overuse of antibiotics can actually cause yeast infections, as well as lead to drug-resistant bacteria that are tougher than a chew toy made out of titanium. When your dogâs immune system is weakened, these superbugs can wreak havoc on their body, causing even more health problems.
In fact, some infections caused by drug-resistant bacteria can even be fatal!

Allergic Reactions

Just like humans, our furry friends can also develop allergic reactions to certain antibiotics, leading to a variety of symptoms ranging from mild skin rashes to severe anaphylactic shock.
But what causes this type of allergy, you might ask? Itâs simple!
Antibiotics, though helpful in fighting off infections, are made up of all different chemical components that some dogsâ immune systems may deem as foreign invaders.
To fight off this unfamiliar substance, your dogâs immune system will trigger an allergic reaction, which can lead to a plethora of uncomfortable symptoms.
Symptoms of antibiotic allergies in dogs can vary from mild to severe, depending on the severity of the reaction. Mild symptoms may include:
While severe symptoms can lead to vomiting, diarrhea, breathing difficulties, and in rare cases, anaphylactic shock - a potentially life-threatening condition.
Some common antibiotics that may cause allergies include:
Behavior Changes
As you can see, antibiotics can have a pretty significant impact on a dogâs gut health, immune system, and more. But thatâs not all!
Antibiotics can also have a negative impact on your dogâs mood and behavior.
Letâs take a closer look at why this happens.
As we know, antibiotics are designed to kill off harmful bacteria in the body. But unfortunately, they can also kill off some of the good bacteria that live in our pup's gut - you know, the ones that help with digestion and keep everything running smoothly.
Without enough of these âgoodâ bacteria present, our four-legged friends can start to feel lethargic and may also develop tummy troubles. As a result, they may become more agitated or irritable, which is no fun for anyone involved.
These side effects can be even more pronounced for dogs already dealing with an existing health problem.
Restoring Gut Health with Probiotics
Now to introduce the hero of todayâs story - you guessed it, probiotics!
Probiotics are the good guys - the Robin Hoods of the gut world. They help restore balance by increasing the number of good bacteria in your dog's gut, thereby enhancing overall gut health.
This tiny but mighty army of microorganisms not only improves digestive function by breaking down food and absorbing nutrients, but they also play a crucial role in modulating the immune system.
In essence, probiotics are the first line of defense for your pupâs digestive system. But when an antibiotic enters your dogâs body on a mission to seek and destroy, these microorganisms will be killed, leaving the gut defenseless against other potential invaders.
Thus, it is essential for us to replace these fallen soldiers before any more damage occurs.
Research shows that probiotics can help reduce the risk of infections and other illnesses by stimulating the body's natural defense mechanisms. They can even lift your dog's mood by regulating neurotransmitters that are responsible for mood and behavior.

So, apart from being the de facto immune system defenders, probiotics can also help keep Fidoâs spirits high. But wait, there's more!
Probiotics can also help prevent future infections by restoring the âgoodâ bacteria that were lost during antibiotic treatments.
Additionally, by promoting the presence of beneficial microorganisms, probiotics can help reduce the risk of antibiotic-associated diarrhea, among other unpleasant side effects that come with antibiotic use.
But what about those dogs who have to take antibiotics long-term? Can probiotics help with that, too?
Letâs find out.

Long-Term Antibiotic Use
When you give your dog antibiotics over a prolonged period of time, the âbadâ bacteria that the antibiotic should be targeting may become resistant, while the âgoodâ bacteria gets wiped out.
Then, your dog's gut microbiome, or the collection of microorganisms that live there, becomes imbalanced, leading to digestive distress and other such problems.
Not only that, but antibiotics can also put a strain on your dog's liver and kidneys, as these organs are responsible for metabolizing and eliminating the chemicals in your dogâs medication. In some cases, long-term use can damage these vital organs, leading to chronic health issues.
Plus, as we know, antibiotics may disrupt your dog's immune system, which could make them more susceptible to infections and illnesses in the long run.
And thatâs not even to mention the potential side effects that your pup may experience during antibiotic treatment, such as vomiting, abdominal pain, and diarrhea.

Long-term use of antibiotics is like playing a bad game of "would you rather": Would you rather put up with a little sniffle, or spend your days hunched over with stomach cramps?
Dysbiosis
Long-term antibiotic use can also contribute to a harmful condition known as Dysbiosis - the âbad boyâ in the world of gut health.
When a dog takes antibiotics, these drugs don't just target the âbadâ bacteria causing an infection - they also wipe out the âgoodâ bacteria in their gut. It's like a nuclear bomb. And just like with any war, there are casualties on both sides.
So, what are the consequences of this gut microbiome massacre? Well, here's where it gets interesting.
Dysbiosis can lead to a whole host of issues, from mild digestive problems like diarrhea and vomiting to more serious conditions like colitis, food intolerances, and even behavioral changes. But fear not, fellow dog enthusiasts, for there are ways to prevent antibiotic-induced dysbiosis.
The key is to use antibiotics only when necessary, and to supplement with probiotics to replenish the âgoodâ bacteria in your dogâs gut.

It's like rebuilding a city after a natural disaster - in order to repair the damage caused by this nuclear event (antibiotics), you have to bring in the construction workers (probiotics) to rebuild.
The Science Behind Giving Probiotics To Dogs on Antibiotics

Studies have shown that supplementing your dogâs diet with probiotics can help maintain a healthy gut microbiome despite antibiotics doing their dirty work.
But don't just take our word for it! Letâs take a look at what the experts have to say.
According to the Veterinary Information Network, âAntibiotic treatment results in dramatic changes in gut microbiota composition and in some patients this can develop into a more chronic intestinal dysbiosis. Probiotics support restoration of the commensal flora.â
Meanwhile, MDPI published the results of a meta-analysis of 17 randomized controlled trials (RCTs), which found that probiotics can be useful in the prevention of antibiotic-associated diarrhea in outpatients taking oral antibiotics, with an overall relative risk reduction of 0.46.
Additionally, an article published by Todayâs Veterinary Practice states that âthe most promising applications for probiotics are treatment of acute uncomplicated diarrhea, prevention of stress diarrhea, prevention of antibiotic-associated GI signs, and adjunct therapy for chronic enteropathies.â
Meanwhile, MDPI published the results of a meta-analysis of 17 randomized controlled trials (RCTs), which found that probiotics can be useful in the prevention of antibiotic-associated diarrhea in outpatients taking oral antibiotics, with an overall relative risk reduction of 0.46.

Tips for Administering Probiotics to Dogs on Antibiotics
There are currently two known and acceptable ways to give your dog his daily dose of probiotic goodness: supplements and probiotic-friendly foods.
Probiotic Supplements

First up, we have the maximalist's dream: probiotic supplements. These puppies (pun intended) are absolutely loaded with the good stuff, including a high concentration of âgoodâ bacteria that ensures your dog is getting a therapeutic dose each and every time.
At Tails Nâ Tummies, the main ingredient of our probiotic supplement is an innovative, âgoodâ bacterial strain known as Lactobacillus Plantarum. Jam-packed with over one billion CFUâs (live microorganisms) per unit and boasting a delicious pork flavor, you canât go wrong with this one!
Probiotics can also help replenish the âgoodâ bacteria in your pupâs gut after completing a course of antibiotics!
Probiotics and antibiotics can safely be given at the same time, though experts do recommend waiting 1-2 hours after giving the antibiotic to administer your pupâs probiotic supplement. So if you give the antibiotic at 8AM, best practice dictates waiting until 9 or 10 AM to give the probiotic.
Probiotic-Friendly Foods
But wait, hold on to your leashes! There are also many food-based alternatives for your pup's probiotic needs. If you prefer a more minimalistic, natural approach, try selecting foods that are already naturally rich in probiotics, such as:
Disease
But if you choose this route, just don't be surprised when your dog starts begging for Kombucha and Kefir like a hipster at a health food store!
