Like humans, dogs have hundreds of different types of bacteria in their gastrointestinal tract. A healthy gut microbiome is key to your pup’s overall health. When the gut is healthy, your dog is likely to feel his best from the inside out. 

If there’s a bacteria imbalance, where bad bacteria outnumber the good, there’s an increased risk of all sorts of health issues, including poor immune function, digestive problems, and even diabetes.

Other factors, such as medications and your dog’s diet, directly impact gut microbiome health. The good news is that your pup’s microbiome can be totally restored, even without using medications.

Other ways to improve your pup’s gut health

Supplementing your dog’s daily regimen with supplements like prebiotics and probiotics are only one way to boost his gut health. Here are some other things you can do to protect, support, and restore your dog’s gut microbiome.

Reduce your dog’s stress

Stress has negative effects on your dog’s gut microbiome health. When it’s damaged or outrun by bad bacteria, your pup’s body goes into a cycle of stress, which causes hormonal changes in the body. 

Most notably, stress causes the body to release cortisol. Chronic high levels of cortisol can have lasting impacts on your dog’s health, including increased blood pressure and a weakened immune system.

There are many things that can trigger stress in your furry friend, including:

  • Change in routine

  • Change in environment

  • Illness

If your dog is stressed, you’ll likely notice telltale signs and symptoms like loss of appetite, increased aggression, and avoiding contact with humans and/or other dogs.

To minimize the amount of stress your dog is exposed to, maintain a comfortable environment. This includes a comfortable place to sleep, food, and clean water along with plenty of love and affection. If your dog is sick, take him to the vet to get the treatment he needs.

Keep your dog active

Exercise naturally reduces stress levels and boosts feelings of happiness for humans and dogs alike. Be sure to keep your dog active by implementing a healthy exercise routine. Whether you go for a walk, take a jog in a local park, or play fetch in the yard, make sure you give your pup time to romp and have fun.

Exercise stimulates the release of endorphins which reduce stress. Keeping your dog active benefits the two of you!

Schedule regular vet checkups

Your dog should go to the vet at least once a year for his annual checkup. Your vet has the experience and expertise needed to address any health concerns while also testing for any underlying problems.

Regular trips to the vet also greatly reduce the risk of a disease going undiagnosed and untreated. If your dog is generally in good health, taking your dog to the vet once a year for a general checkup should be plenty.

However, if your dog is older or has a chronic disease, seeing the vet more often is ideal.

Final thoughts

Knowing how to support and protect your dog’s gut plays a crucial role in keeping him healthy for years to come. We highly recommend the 20 dog gut health supplements that we’ve listed above. Whether you choose to give your pup a gut-boosting treat, capsule, or broth, you can have peace of mind knowing that you’re doing your best to make sure that your dog is happy and healthy.
