Learn More About Probiotics for Dogs

Probiotics containing naturally occurring ingredients tend to be beneficial for dogs. The best way to determine which probiotics are best for your dog is to read the product descriptions and reviews on Petco after consulting your veterinarian about your pet’s specific needs.

Probiotic products are made for a variety of dogs experiencing different circumstances and in various life stages. When determining which probiotic to give your dog, be sure to consider your dog’s digestive habits, age and any allergies your dog may have.

No, dogs should not take human probiotics. They do not provide the same benefits as probiotics created especially for dogs.

When given appropriately, probiotics can be very beneficial for dogs. They contain a variety of beneficial bacteria, microorganisms, digestive enzymes and live cultures that can help provide support for the overall gut wellness of your dog.

No, dogs cannot overdose on probiotics due to probiotics lacking harmful ingredients. Too much good bacteria can, however, upset a dog’s digestive system, causing excessive gassiness, diarrhea and other side effects. Stick to the supplement schedule that you set with your vet or follow the dosage instructions from the product you choose.

Probiotics have been proven to increase overall gastrointestinal function in dogs. Be sure to read the product description to ensure you purchase a probiotic supplement that will best benefit your dog. To help your pup’s digestive system, consult your veterinarian about which supplements or dog health and wellness solutions will work best. They may also suggest switching your pet to a minimally processed dog food diet.
