Pet Probiotics Side Effects: What to Watch Out For and How to Take Them Safely

Pet probiotics have gained popularity for their potential to boost digestive health, enhance the immune system, and promote overall well-being in our furry companions. While these beneficial bacteria can offer numerous advantages, it's crucial to be aware of potential side effects and how to prevent them. 

As responsible pet parents, understanding the possible adverse reactions and implementing preventive measures ensures our pets reap the full benefits of probiotics without any discomfort. In this article, we'll explore the common side effects of pet probiotics and the steps you can take to prevent them. 

Hold On, Can Pet Probiotics Cause Side Effects?

We've hailed pet probiotics as the tiny gut superheroes working wonders for our pets, and rightfully so! After all, they're live bacteria, earning their nickname "friendly bacteria" for a reason. While side effects or negative reactions are rare, it's important to remember that introducing any new element, even something good, can require an adjustment period.

Think of it like introducing a new playmate to your pet. There might be some initial "getting to know you" moments. Similarly, your pet's gut microbiome might experience a temporary shift as it welcomes these new probiotic residents. This can occasionally lead to some minor side effects that are usually temporary and easy to manage. 

Common Side Effects of Pet Probiotics

Here’s a closer look at some of the more common side effects you might encounter: 

Digestive Upset

Symptoms: Gas, bloating, diarrhoea, constipation, vomiting, loss of appetite, changes in stool quality 

One of the most common side effects of introducing probiotics to your pet is digestive upset. This refers to a range of gastrointestinal symptoms or issues, and are typically mild and temporary, as your pet's digestive system adjusts to the new beneficial bacteria. To minimize these effects, start with a smaller dose (e.g. use half or a quarter of the recommended dose) and gradually increase it over time.

Changes in Appetite

Some pets may experience a change in appetite when first starting probiotics. They might eat less or show less interest in their food. This reaction is usually temporary and should resolve as your pet's body adapts to the probiotics. Monitor your pet's eating habits closely and consult your veterinarian if the changes persist.

Allergic Reactions

Symptoms: Itching, swelling, hives, difficulty breathing

Though rare, some pets may have allergic reactions to specific strains of probiotics or other ingredients in the supplement. Before purchasing, ensure that you look through the ingredients and choose a product free from allergens such as soy, wheat, dairy or artificial additives to prevent allergic reactions. 

Seek immediate veterinary attention if a dog is suspected of suffering from an allergic reaction to probiotics. 

Increased Thirst

Symptoms: More frequent urination, increased water consumption.

Some pets may drink more water than usual when taking probiotics. This could be a sign that the body is working harder to process the new bacteria. Ensure that your pet always has access to fresh water and monitor their water intake to ensure it’s not excessive.

Lethargy

Symptoms:  Reduced activity level, excessive sleepiness, lack of interest in playtime or walks

Occasionally, pets might exhibit signs of lethargy or reduced energy levels when first starting a pet probiotic regimen. This usually happens because the body is working to adjust to the influx of new bacteria in the gut.

What You Can Do 

While most pets experience no issues when starting probiotics, some might encounter a few temporary side effects as their gut microbiome adjusts. Here are some tips to minimise the risk of these side effects and ensure a smooth transition for your furry friend.

• Start Low, Go Slow: This is the golden rule when introducing any new supplement to your pet's diet, including probiotics. Begin with a very small dose (¼ of the recommended amount) for the first few days. Gradually increase the dose over a week or two, allowing your pet's system to adjust comfortably.
  
  
• Choose the Right Probiotic: Not all pet probiotics are created equal! Talk to your veterinarian about selecting a high-quality probiotic specifically formulated for your pet's species and age. Look for a product containing a variety of beneficial bacterial strains tailored to their unique needs.
  
  
• Consider a Sensitive Formula: If your pet has a sensitive digestive system, consider a specially formulated "sensitive" probiotic supplement. These often contain prebiotics (food for good bacteria) which can further aid gut health and minimise digestive discomfort.
  
  
• Monitor Closely: Pay close attention to your pet's behaviour and bowel movements after starting probiotics. If you notice any concerning changes like persistent diarrhoea, vomiting, or significant lethargy, discontinue use and consult your veterinarian.
