  8. Better Communication Helps to Alleviate Stress
A situation that stresses one dog may not affect another dog and some situations will stress all dogs to one degree or another. Why the difference? Well, every dog is an individual with his/her own unique disposition, physical and psychological strengths and weaknesses. 

Dogs are subject to the same basic factors that affect our ability to remain immune to, trigger on and cope with stress - for example...
  • Inherited traits;
  • Acquired traits;
  • Diet and nutrition;
  • Available support structure, etc.

If your dog happens to have heightened sensitivity additional stress may be generated if you are not aware of and/or do not understand heightened sensitivity. If you have not had the opportunity to hone your communication skills and your own sense of self awareness dealing with your dog’s stress can be a very difficult matter.

1.0 Typical Causes of Stress, Anxiety,
      Depression, Aggression in Dogs

A partial list…
Dogs can become stressed for many reasons…
  • Natural predisposition which is inadvertently enabled by the dog’s human - for example:
    • A dog that has heightened sensitivity can become stressed resulting in anxious behaviour if the dog’s human does not learn to be an effective communicator;
  • An unfamiliar situation:
  • Surgery and injuries;
  • Under-socialization;
  • A sudden traumatic event – emotional and/or physical for example;
    • The passing of a loved one - grief;
    • The sudden move of a family member away from home;
    • An emotionally destabilizing encounter reinforced by discomfort of the dog’s human – i.e. an attack by another dog while in a dog park;
    • A violent thunder storm, wind storm, etc.
    • Fireworks, gun shots, etc.
  • A condition that is inadvertently created and teaches the dog to be in an altered state of normal, for example:
  • Tension resulting from proximity to animate and inanimate objects – situations and locations, people, other animals, objects associated with tension that creates stress due to fear resulting in avoidance, aggression etc…
A condition that creates a situation where the dog is at physical and/or psychological disadvantage that results in a deficiency of the basic requirements of life…
    • Healthy diet;
      • A truly good diet supports a healthy mind and body;
      • An inadequate diet and/or a toxic diet creates instability in mind and body;
  • Safe home;
    • A physically safe environment promotes confidence; an inadequate environment promotes stress;
  • Structure that enables positive, balanced physical and mental output.
When parts of this formula are missing, stress and anxiety are a likely outcome even in the absence of a sudden trauma.

A psychologically safe environment in which a dog is understood, properly directed, provided with structure and both physical and mental stimulation is stabilizing and helps to build a firm foundation for weathering stressful situations.

3.0 Long-Term (Chronic) Stress is a Health Threatening

On a long-term basis stress (psychological and physical – i.e. dietary insufficiency) can trigger further health issues, for example:
  • Suppression of the immune system - thereby leaving the body more susceptible to:
    • Disruptions in the endocrine system; 
    • Inflammation;
    • Infections, such as:
      • Eye infections;
      • Ear infections,
        • Ironically when eye and ear infections are treated with antibiotics (rather than with natural remedies for ears and natural remedies for eyes), greater stress - physical and psychological results due to the fact that:
          •  Antibiotics kill good bacteria in the GI tract along with bad bacteria;
          • The elimination of good bacteria destroys the health-giving flora of the GI tract placing additional stress on the immune system and on the psychological state as serotonin levels in the GI tract are also adversely affected.
    • Insect and parasite infestation;
    • Fatigue and pain;
    • Low serotonin levels - thereby affecting brain function and behaviour;
    • Viruses.

4.0 Conventional Chemical-Based Drugs to Control
      Stress and Symptoms

Chemical-based anti-depressants such as Reconcile (also known as doggie Prozac, a selective serotonin reuptake inhibitor – SSRIs) are often prescribed by allopathic veterinarians in an attempt to control the symptoms of stress. While SSRIs may seem to provide some amelioration of symptoms for the short term, SSRIs will not cure the condition and in many cases may make the situation worse – the consequences of which can be very serious and can shorten life span. SSRIs often have severe side effects, may actually mimic some of the symptoms of the condition being suffered and may become an impediment to actually solving the root cause of the stress. 

There are many natural, safe ways to safely boost serotonin levels without putting a dog’s health at risk. In-fact naturally boosting serotonin levels via diet comes with other very important health benefits.

Then there are other symptoms and their ill effects that may need to be addressed. Symptoms such as hair loss and skin irritation due to excessive licking and scratching. The use of steroids such as prednisone can cause an additional burden of stress and further deterioration of health. Consider natural alternatives to steroids and non-steroidal anti-inflammatory drugs (NSAIDs).

5.0 Other Products that Claim to 'Solve' Anxiety, Stress
      and Symptoms

There are a lot of products marketed to 'solve' anxiety, for example:

The Thundershirt
The Thundershirt is a product that has been aggressively marketed - but is it really the 'solution' to anxiety as claimed by the manufacturer? 
I don't think so.

While the Thundershirt may have some value in some circumstances to ameliorate some or a single symptom of anxiety it is not the panacea for cure that is evoked by the product’s labeling as a "proven solution for dog anxiety”.
If you would like to understand more about my thoughts on the Thundershirt you can read here

Pheramone Collars, Herbal Spray Collars, Bach Flower Essences, Rescue Remedies
Pheromone collars and herbal spray collars are also promoted by some behavourists,  trainers and veterinarians as a solution to anxiety - you can read (in detail) about my thoughts on these products here.

The bottom line - in my opinion these products may have some value in some circumstances to ameliorate some or a single symptom of anxiety but they are not a panacea for curing the condion of anxiety.

6.0 Diet Can Create and/or Exacerbate Stress
      Diet Can also Help to Alleviate Stress...

A poorly designed diet can create both physical and mental stress on its own or can contribute to an existing stress from other sources. 

Although many pet food manufactures like to advertise their pet food as: nutritionally complete, science-based etc. these terms are unregulated. 

The manufacturer can say what they want to without substantiation. 

There are many examples of unsubstantiated if not outright deceitful claims or of negligence by silence exercised made by pet food manufacturers that  include specious if not downright health threatening substances in their products. And AFFCO certification  should not and can not be relied upon as a guarantee of a good dog food.  to Ingredients such as:
  • Probiotics’ that are non-viable (dead) as the living microbes that make a food probiotic cannot withstand the heat of processing required to make the product – i.e. dry dog food, wet cooked dog food.
    • This is, at the very least innocuous, and at worst harmful in the case of those that believe they are meeting their dog’s need for healthy gut flora when in fact no healthy gut support is available from the product;
  • Fish meal that contains ethoxyquin, a known: allergen, behaviour problem trigger carcinogen, cause of deformities in puppies, toxin, skin problem trigger, organ failure trigger – you can read about ethoxyquin here;
  • High pesticide residue ingredients like corn, soy, canola oil, etc.
  • Grains such as rice that are not screened for aflatoxins;
  • Artificial food colouring and preservatives;
  • Food that is advertised as containing Omega-3, however the amount of Omega-3 included is insufficient;
    • No dog food contains sufficient amounts of Omega-3 fatty acids;
    • Ingesting an insufficient level of Omega-3 fatty acids has an enormous impact…
    • On your dog’s mental health – you can read why here, and;
    • On your dog’s physical health – you can read why here;
    • Go here for a complete guide on adding Omega-3 fatty acids to your dog's or cat's diet.
It is very important to understand that no dog food is nutritionally complete on its own – this includes homemade raw or cooked and commercial processed dry and wet or raw dog food. It is also why my homemade dog food recipe outlines important supplements to be added to food at meal time.

There are certain supplements that are required for each option (homemade or, commercial) in order to make the diet nutritionally complete and therefore health-supporting and stress-suppressing.

One more thing in common between dogs and humans – both species have more serotonin in the gut than in the brain – when god gut health is not supported behaviour is affected.

A poor diet adds to the creation and maintenance of stress and anxiety.

7.0 Herbs Can Help Alleviate Stress Too

There are many herbs that can help to support health and help to alleviate stress - here are a few such examples...
 Arnica Montana;
Lemon Balm; 

8.0 Better Communication Helps to Alleviate Stress

Dogs are very insightful communicators - much more so than the average human. The significance of this is huge. Because dogs can sense and discern to a degree that exceeds that of an untrained human, It does not matter what you say as much as what you feel. 
How you feel at any one given moment instantaneously transmits itself to:
  • Your body in the form of body language;
    • Facial expression;
    • How you hold yourself - how one part of your body relates to another part of your body, your posture, etc.
    • How you occupy your space, and;
    • How you occupy the space you are located in:
      • Where you are in that space;
      • How the various parts of your body are positioned in relationship to other parts of your body;
      • The footprint are you occupying;
      • How you move, etc...
    • How you present yourself;
    • How you feel and the impacts of that on;
      • Your breathing;
      • Your adrenalin level;
      • Your heart rate;
      • Your blood pressure;
      • Your blood sugar;
      • Your scent.
Your thoughts and your emotions drive your body language...

Whatever you want your dog to be you must be that thing first. Your thoughts and emotions provide direction to your dog - more so than the words that you speak. It is not about being the ‘alpha’ a much misused term. It is about directing from a place of pure logic, with insight, fairness, honesty, self-awareness, self-discipline, self-restraint, respect and true patience. Arguing with your dog simply serves to create stress for both dog and human. All too often the human expects the dog to be what the human is not first willing to be themselves. While at other times it is not that the human is not willing – it is instead because the human has not had the opportunity to understand how to direct effectively. When we work to train ourselves what we learn can translate directly in the most positive ways to our dogs.

It is important to understand that it is not that we can never feel anxious, depressed, sad, stressed, fearful around our dogs. It is instead to say that in those moments when you seek to direct your dog you must do so by first reflecting what it is that you want your dog to be and your dog will follow your lead. 

Never feel sorry for your dog, never feel guilty as these are destabilizing emotions to both the dog and the human. Instead ensure that your thoughts are in alignment with what you want your dog to feel – this is leading by the right example.

  1. I have an American Dingo. She was found in the mesa when she was about three-four weeks old (according to the vet). She is now two. Since we got her, almost to the day, she has had a habit of sucking on blankets and kneading it at the same time, almost like she would have suckled on her mom. I do notice she does it more when she is stressed, but even when things are calm and good, she will do it too. Is this ONLY a sign of her being stressed or something else????

    1. Cause is insecurity which leads to anxiety - which cause a constant state of underlying stress - which is why she does it when things are calm. When other sources of stress are present the level of anxiety increases so the habit becomes intensified. All fixable when gone about the right way.

  2. I have a five year old female Yorkshire terrier and just this year we decided to get her a companion. It is a male Australian yorkie and she has been much happier with him around and not so lethargic. It's been about 3mths now and we are noticing that she has been really clingy to me and at night, she has started not coming to sleep with us, but instead, sleeping under the couch. We have to go and coax her out and let her lay up beside me for her not to be upset and run off. This started happening suddenly and i know our actions are enabling her inappropriate behavior but i am unsure of what else to do and what the underlying cause could be of her sudden, random behavior. Thanks for any advice!

Note -

1.0 Use of Foods, Herbs, Nutraceuticals and Alternative Medicines:

When choosing to use any of the items or protocols in the article above, it is your responsibility to ensure safe use of the item/protocol. Food, herbs, nutraceuticals and alternative medicines all have drug interactions, most have health issue contradictions, some have side effects. Use of substances and protocols are your responsibility. Prior to use of any substance or protocol make sure you do your research - check for all cautions, contradictions,interactions, side effects. If in doubt do not use the substance or protocol. If the substance, or protocol is contradicted for your animal do not use. If your animal has an underlying condition you are not aware of substances may conflict with that condition.

2.0 The Real Meaning of Holistic…

Food, herbs, nutraceuticals and alternative medicines are NOT ‘holistic’ they are a substance and MAY, or may NOT be ‘NATURAL’. It is important to keep in mind that the supplement industry is just as unethical as BigPharma, the Food and Pet Food Industry, and unfortunately many veterinarians.

If you use a ‘natural’ substance (i.e. an herb) you are using a natural substance, this is not synonymous with holistic.

Holistic is a way of approaching life, and within that - overall health, and wellbeing.

Please do not expect a natural substance to miraculously remedy a health or behavioral situation. A natural substance may be used to treat symptoms. However, if the factors causing the underlying issue are not properly identified, analyzed and addressed you do not have a remedy.

Remedy requires a comprehensive approach that identifies root cause, seeks to remove items that trigger, cause or otherwise contribute to issues, and builds a complete, and detailed approach to immediate treatment, remedy, and maintenance of long-term health = holistic.
