Gut Health, Immunity and Microbiome

At first glance the digestive system appears to have a very simple task of taking in food, digesting it, absorbing nutrients, and then excreting the waste, and while everything is in good working order, we never even give it a second thought. 

It is in fact an incredibly complex structure with a vast number of tasks to undertake. The more the gut is studied the more we realise the vital role it plays in achieving optimum health, disease prevention, and stabilising our emotional state.

 

Although the teeth are needed to some extent to bite, crush and tear off food the actual process of digestion doesn`t start until it reaches the stomach. With no digestive enzymes in the saliva to kick start it off, the food needs to quickly get where the real work begins, which is in the stomach.

 Oesophagus:

Is a long muscular tube that runs down the neck, passes through the diaphragm and uses strong contractions to push food directly into the stomach.  

 Stomach:

The stomach lies at the front of the abdominal cavity, tucked just behind the liver and acts like a big mixing bowl.  

Any incoming food is first subjected to an acid bath of around ph1, this immediately gets to work breaking down protein and also killing any harmful bacteria.

The walls of the stomach are lined with a thick mucous which provides protection from the strong acid as well as stopping the stomach from literally digesting itself.

As the stomach expands with food, a peptide hormone called gastrin is released, which in turn triggers more hydrochloric acid and digestive enzyme production.

To aid digestion even further the surface of the stomach is a mass of wrinkles and folds which expand and contract to grab food particles and perform a churning or chewing-like action.

At this point, the thick soup-like constancy of partly digested food and secretions is known as chyme.

The food has now been in the dogs stomach for anywhere between five and ten hours and its next destination is the duodenum, the first section of the small intestine.

 Pancreas

The pancreas is a small gland, which sits next to the stomach and is attached to the small intestine, here it transports digestive enzymes through two excretory ducts into the duodenum.

The enzymes it produces are amylase to help digest starch, lipase to digest fats and trypsin and chymotrypsin to deal with the protein.

Enzymes are needed to break down food into tiny molecules and allow the absorption of nutrients into the cells of the intestines which then go on to be released into the bloodstream. 

It also produces and secretes the hormones insulin and glucagon that regulate blood sugar levels. The higher the concentration of sugar in the diet the more insulin is secreted into the bloodstream and the harder the pancreas has to work.

Liver

The liver is the largest gland in the body and the only organ that has the potential to regenerate after disease or injury.

Its many crucial jobs include producing bile to assist the small intestine in breaking down and absorbing fats and to process the nutrients that are absorbed by the small intestine.

Its other roles include storing vitamins and minerals, acting as a filter for toxins in the bloodstream and as a glycogen store for when extra energy is needed. 

 Small intestine

The small intestine is made up of three sections, Duodenum, Jejunum (longest) and the ileum (shortest)

On receiving the nutrient-rich chyme from the stomach, it is joined by secretions from the liver, gallbladder and pancreas to further assist in the digestion process.

The small intestine is lined with millions of tiny finger like projections called the Villi, these act to increase the surface area in order to trap and absorb as many nutrients as possible.

Most of the absorption of nutrients takes place in the small intestine, which are then released into the bloodstream to travel throughout the body to be utilised by the cells.

The final and shortest part of the small intestine is called the Ileum, here the food gets broken down even further in preparation to enter the cecum, the first section of the large intestine.

 Large intestine :

The large intestine is made up of the cecum, colon and rectum.

Its purpose is to remove water from the faeces, keep electrolytes in balance and to prepare and temporarily store any indigestible matter for excretion.

But there is much more activity going on in the colon than just that and although not a very glamorous area of interest, it does deserve our full care and attention.

The large intestine has a high concentration of bacteria referred to as the

Microbiome.

This is a collection of microbes made up of bacteria, viruses and fungi that we all have in our gut for efficient digestion, absorption of vital nutrients and to build a strong immune system.

 Our dogs would have acquired their unique bugs from their mother at birth and developed others depending on the environment they lived in and the food they ate.

The delicate balance of the microbiome can easily be disrupted by medication such as antibiotics, periods of stress and anxiety and a poor, unsuitable diet.

When everything is in balance these good bugs work hard to extract as much nutrition as possible out of the food that is consumed and to ensure the smooth running of the whole gastrointestinal tract.  

The bacteria are also responsible for assisting in hormone production such as serotonin, which occurs in the highest concentration thorough out the lining of the gut. 

A thriving, balanced microbiome is absolutely essential for the dogs ability to resist or fight disease, control inflammation in the body and for a positive influence on their mental wellbeing.

 Rectum and anal glands.

The faeces are then ready to be expelled along with the indigestible matter and dead red blood cells that it contains. 

Ideally, the dogs stool will be quite firm, which will press on the anal glands as it is passed, causing the glands to naturally empty.     

 All disease begins in the gut - Hippocrates

 Immunity and the gut

The gut forms between 70 - 80% of the immune system and has a vital role in regulating immunity, protecting our bodies from invaders such as allergens and pathogens and controlling inflammation.  

The food we chose for our dogs and the lifestyle choices we make for them will have either a negative or positive effect on their overall gut health, ability to utilise the nutrients in the food they eat, the essential fuel to grow and repair their body and to thrive well into their senior years.

Joint Supplements for Dogs

Choosing a Joint supplement for our dog can be overwhelming. Andrew the founder of Jointly365, explains why researching the ingredients of a product is so important and ensures your dog gets the best joint support possible.

Here we consider the following:

What ingredients and why?

What to look for when choosing a joint supplement?

Introduction

We all know that as dogs progress from middle to old age they tend to decrease their levels of activity to some degree. This can be due to many reasons, but ageing and stiff joints are one of the most commonly seen. 

Stiff joints are caused by the degeneration of the normal joint structure which leads to the aches and pains that become worse as they get older – which some of us may have experienced ourselves…..

There are many approaches we can take to this progressive condition - such as exercise and weight management, complementary therapies, or prescription medication - and though they will not be discussed here today, it is important to remember a holistic and multi-pronged approach to stiff joints is always the best way forward.

Today we will be discussing joint supplements - one of the most commonly used methods to help dogs with stiff joints.

But with so many out there to choose from, how do you choose one that is best for your dog?

My simple approach to this is there are only two things you can do with a supplement: soothe the stiff joints themselves, and provide the necessary structural ingredients that a joint requires to function as well as it can.

If you can successfully achieve both, you are on the right track. Only achieving one or the other, is a sub-optimal and unnecessary situation.

The provision of structural ingredients is a more simple topic, and will be looked at shortly, but soothing joints and working with the bodies own natural anti-inflammatory system is a more complex area.

One of the most studied and effective methods of achieving soothing joints is by using marine sourced omega 3 oils. These are a type of essential fatty acid – EFA (that has to be eaten as it can’t be made by the body – hence ‘essential’), which moderate the bodies inflammatory response, so helping aching joints. These are hard to provide at high levels in normal food due to rancidity problems during storage.

Even though only a few EFAs such as EPA or DHA are ever discussed, there are dozens of them that contribute to the overall effect in different ways. So the quality and balance of those is critical in achieving the results we want. Some fish oils and mussel powders are of poor quality for what we are trying to do in a joint supplement. And this is where the big issue lies for choosing products – it is hard to know which is which.

Those who are more sure of their product will have conducted a clinical trial and published it, so owners and vets can scrutinise the methodology and results. And you should be looking for high levels of cold water marine sourced Omega 3’s – enough to carry a regulated claim that it can “XYZ”.

The second part of the equation is providing all the structural elements the joint requires, which is critical as this is a long term condition. Depending on the food that you feed your dog, these will be supplied in higher or lower quantities, but rarely to the levels that are provided by a quality supplement.

You should be looking for ingredients that will help the production of the cartilage and joint fluid such as glucosamine, N-Acetyl glucosamine (a special type of glucosamine that is utilised more readily by the body) and hyaluronic acid, that will all help the joint function to the best of its ability.

Additionally, we can help remove free radicals, which speed up the degradation of the joint. High levels of antioxidants such as vitamin E and C are what to look for here.

So if you are using a joint supplement now, remember the condition progresses and you may be able to help your dog more by changing to a more concentrated alternative.

With this in mind, if you feel the supplement you are currently using may not be giving the best response to what is a progressive condition, or just want to start with the better alternatives out there, consider trialling one that contains the ingredients mentioned previously.

And finally, there is also the cost element of the supplement – both financially and environmentally. Generally speaking buying one from your local veterinary practice will be more expensive than elsewhere, due to the profit margins vets operate on, though you will most likely be able to get extra advice at the same time.

And nowadays you don’t need to settle for using blister packs that aren’t recycled or even plastic pots anymore, when there are technically brilliant plastic free packaging materials around. No-one want s to use more plastic than we need to, and with around 12 million dogs in the UK now, we all need to do our bit to help the environment we love to get out into with our dogs.

However using a trusted supplier with a clinical study, the regulatory claim on the pack, who is also able to give advice, usually provides the most value.

 Jointly365 has been developed by Andrew Little BVetMed. Andrew worked in practice for many years before gaining 15 years of product development experience in major animal health companies, including with market leading joint supplements products in UK and abroad. He has combined this experience to focus on dog joints, producing a natural, sustainable, plastic free joint supplement, with both soothing and structural ingredients carefully chosen and tailored to provide the very best for your dog - that is roughly half the price of veterinary alternatives to ensure as many owners as possible can access quality care for their dogs.
