Chronic Colitis in Dogs


Gracie’s Story

Let me introduce you to Gracie (pictured above). Gracie is a 12 year old female Cavoodle who lives on the Gold Coast in Australia.

Chronic Colitis in dogs- Signs

The next diagnostic step was to pursue colonoscopy, but given that nutritional management is often an effective strategy for chronic colitis, the specialist decided to start with a diet change. Gracie was transitioned to a food that has been especially formulated to support a dog’s digestive health.

Chronic Colitis–Nutritional Management

What food Gracie was changed to? It was Hill’s Prescription Diet Gastrointestinal Biome.


Before we talk more about this revolutionary food,  let’s refresh our knowledge of the microbiome. Think of the microbiome as a mini- ecosystem located in the pet’s digestive tract containing billions of microbes and other microorganisms — including both desirable and undesirable bacteria, and it is unique to each pet. By using nutrition to balance a pet’s gut microbiome, we can influence the transition between acute or chronic disease and overall health and well-being. You can learn more about the microbiome here.

Hills Prescription Diet Gastrointestinal Biome contains ActivBiome+ technology which is a proprietary blend of prebiotics shown to nourish the gastrointestinal microbiome, increasing the number and diversity of function of beneficial bacteria helping them to outcompete pathogenic bacteria.  These beneficial bacteria in turn produce gut-nourishing short chain fatty acids, and release and activate antioxidant and anti-inflammatory polyphenols.  Nutrition provides  a practical and long-lasting strategy to maintain a healthy balance of gut microflora and promote overall health.

Hills Prescription Diet Gastrointestinal Biome


There are many indications for Hill’s Prescription Diet Gastrointestinal Biome including acute and chronic colitis, constipation, diarrhoea, chronic enteropathy (fibre-responsive, antibiotic responsive and immunosuppressive responsive) and stress diarrhoea in both dogs and cats. 


With Hill’s Gastrointestinal Biome, you can harness the power of the microbiome to improve the digestive health and overall well-being for pet’s like Gracie with every single meal!

According to Gracie’s owner -:

Gracie's poop

“The change in Grace was dramatic, within a few days. Once we commenced the new food her faeces started being pebble like.   Gradually (within a few weeks) her faeces returned to a more normal presentation and [they have] continued to be normal without the blood and mucus.  I do not think my dog would have survived had this food not been available. She is much happier, as is her mum!”
