Leaky Gut Syndrome In Dogs – What Are The Symptoms?

Leaky Gut Syndrome in dogs can lead to many unwanted symptoms that are frustrating for both the pet and for the pet owner who cares for his or her fur baby.  Symptoms of Leaky Gut Syndrome include unexplained allergies, gastrointestinal distress, changes in mood or behaviour, and chronic infections. 

If you feel that your dog’s health is compromised but you have no logical answer as to why, Leaky Gut Syndrome may be to blame.  Here, leaky gut symptoms in dogs will be explained as well as what you can do if you suspect your pet is suffering from this common syndrome.

What is Leaky Gut Syndrome?

Leaky Gut Syndrome is a condition that affects the lining of the small intestine.  Inflammation weakens the mucosal lining of the gut, which leads to food particles, bacteria, and toxins entering the bloodstream through the intestinal wall.  Once these foreign objects enter the bloodstream, the immune system attacks, leading to chronic inflammation.  Over time the daily (or hourly) attacks lead to chronic disease and poor immune function.

Leaky Gut symptoms in dogs

Leaky Gut Syndrome is believed to be extremely prevalent in dogs; however, the diversity of symptoms can make it difficult to diagnose. Here, some of the most common leaky gut symptoms in dogs will be discussed.

Gastrointestinal distress

Perhaps one of the most telltale leaky gut symptoms in dogs is gastroenteritis.  Vomiting, diarrhea, loose stools, and gas (particularly if allergies to food have been ruled out) are all signs that your dog is suffering from Leaky Gut Syndrome.  When food particles consistently breach the intestinal lining, the immune system begins to recognize daily foods as toxins and reacts accordingly by eliminating food from the body as quickly as possible. 


When the immune system is overworked, lethargy is likely.  Chronic inflammation, which is a byproduct of immune system stress, leads to feelings of fatigue caused by the constant internal onslaught of mediator release brought on by white blood cells.

Weight gain/loss

Weight gain or loss are both common leaky gut symptoms in dogs.  Weight gain can occur in the form of puffiness and water retention, caused by the effects of chronic inflammation.  On the other hand, weight loss is sometimes noted, due to malabsorption of nutrients in the gut.

Change in mood/behavior

Changes in mood and behavior, as well as long-term behavioral issues such as anxiety, can all be symptoms of leaky gut in dogs.  Gut bacteria have been shown to have an increasingly important role in mood regulation.  Mammals with imbalanced gut bacteria (a hallmark of Leaky Gut Syndrome) will have a more difficult time regulating moods and will be more prone to issues such as anxiety or depression.   

Poor recovery

If your dog is involved in canine sports or hunting, recovery is of major importance.  If you find, however, that your dog inexplicably struggles to recover from hard training sessions or days in the field, this could be a sign of Leaky Gut Syndrome.  Chronic inflammation and an overworked immune system results in impaired recovery due to a weakened immune response that is responsible for restoring muscles after a hard workout.

Joint pain

A common misconception is that joint pain and lameness are caused solely by arthritis.  However, the underlying source of joint pain is frequently chronic inflammation, which can settle in joints.  Many pet owners find that when they treat general inflammation, their dog’s “arthritis” disappears!

Allergies / Skin irritation

Other telltale leaky gut symptoms in dogs are allergies and skin irritation.  Dogs have a whole-body histamine response, which causes exposure to allergens to result in inflamed, itchy skin.  When the immune system is constantly triggered, such as in the case of Leaky Gut Syndrome, dogs can have a reaction that mimics that of allergies.  Additionally, allergic reactions can be more severe when chronic inflammation is present.

Chronic Infections

Dogs with weakened immune systems are likely to suffer from chronic infections.  Leaky gut symptoms in dogs include frequent ear infections and upper respiratory infections due to the constant stress placed on the immune system. 

How WINPRO can fight Leaky Gut symptoms in dogs

If you suspect Leaky Gut Syndrome based on these common leaky gut symptoms in dogs, what should be your plan of attack?  The most important aspect of healing Leaky Gut Syndrome is to address inflammation in the gut to allow the immune system to begin the healing process and reduce the chance of toxins leaking into the bloodstream. 

Traditional anti-inflammatory medications are not adequate because they can damage the stomach and intestinal lining, making Leaky Gut Syndrome worse.  WINPRO products, however, utilize the scientifically proven anti-inflammatory power of clinically proven animal blood proteins to reduce inflammation quickly and efficiently. 

WINPRO soft chews are ideal for dogs of all ages, sizes, breeds, and activity levels, and can be safely administered in conjunction with other supplements and veterinarian-prescribed medications with no side effects. 

Unlike traditional nutritional supplements, WINPRO products go to work quickly – or your money back.  WINPRO products can be individualized to your dog’s specific leaky gut symptoms, thanks to five formulations (Immunity for gastrointestinal distress; Focus for anxiety; Mobility for joint health; Training for recovery; Allergy for allergy symptoms). 

Additional active ingredients in each formulation work to boost the effects of animal blood proteins, putting your dog on the road to recovery and back to its normal self safely, effectively, and naturally.
