Why Dogs Need Probiotics?

1. Digestive Disorders

Just like the human digestive system, a dog’s digestive system is home to billions of bacteria that maintain smooth functioning of their gut. But various factors such as infections, long term use of antibiotics or steroids, stress, old age or sudden changes in the diet can lead to imbalance of gut flora in your dog which can result in digestive issues such as diarrhea, gas, cramping, colitis, etc. A probiotic supplement can help to relieve diarrhea cause of stressful situations or excessive antibiotic use. Probiotics also improve the assimilation of vitamins and minerals from foods and aids your dog’s body to process critical nutrients such as vitamin B12.

2. Immune System Support

As stated before, 80% of a dog’s immune system is based in his gut. Different strains of probiotic cultures pair with different parts of the immune system and support its proper functioning which helps to reduce inflammation throughout the dog’s body and reduces his susceptibility to chronic diseases. It also helps to relieve yeast infections and yeast-related skin issues and improve the quality of the fur.

3. Maintain Brain Health

The microbiome present in the gut is responsible for producing the neurotransmitters and neuropeptides that are required for maintaining healthy brain function. The intestine is filled with nerve cells that are connected to the neurones in the brain and probiotics can support the function of these nerve cells. Probiotics also support the synthesis of important hormones such as serotonin and help in DNA repair. No doubt the gut is called the second brain.

When to Give Your Dog Probiotics?

Although, people disagree on the frequency of giving probiotics for dogs, but it is safe to give a moderate potency probiotic supplement to your dog every day. Some experts say that dogs should be given probiotics only when they have digestive upset or when they are under stress or taking an antibiotic medication.

You can give probiotics at different times of the day so that they will work differently depending on the situation in your dog’s GI tract at that time. Dr. Campbell-McBride recommends giving probiotic supplements between meals so that the microorganisms can avoid the harsh gastric juices and acids that are produced during digestion.
