The endocannabinoid system plays a critical role in maintaining homeostasis within the body during periods of oxidative stress (Atalay et al., 2019). The endocannabinoid system is regulated by the ingestion of cannabinoids via hemp products and the animal’s cannabinoid receptor type 1 (CB1 Receptor) and cannabinoids receptor type 2 (CB2 receptor) already present in the body (Atalay et al., 2019). Hemp seeds can be utilized as a resource for food, fiber, dietary oil, or for its medicinal properties dating back hundreds of years (Girgih et al., 2014). Hemp seeds are comprised of 30% oil and 25% protein with current research being focused on how hemp seeds have the ability to discard toxic free radicals in the body (Girgih et al., 2014). When an animal is constantly under high stress or their body is infected with a disease, free radicals and reactive oxygen species (ROS) are over produced in response to these changes and can cause damage to nearby cells (Girgih et al., 2014). The increased number of free radicals and ROS in the body can lead to inflammation and even cell death which will trigger natural cell processes to cease immediately (Girgih et al., 2014). “These effects can cause severe damage to cells, produce a high oxidative stress condition and enhance the development or progression of chronic diseases, such as hypertension, cancer, diabetes and obesity” (Girgih et al., 2014). Oxidative stress is part of the natural aging process and can also be induced if an animal is over-exercised (Sechi et al., 2017).
Oxidative stress can be seen in dogs when they exert themselves to a point of exhaustion. (Sechi et al., 2017). Oxidative stress caused by too much exercise for a dog may lead to increased muscle fatigue, muscle fiber damage, and may even advance to damaging their immune system (Sechi et al., 2017). This has been seen in animals that race such as dogs and horses as well as animals that compete in physical exercise competitions (Sechi et al., 2017). Within an animal’s body, their muscles and blood system are enriched with antioxidants to combat the destruction of free radicals (Sechi et al., 2017). Natural metabolic reactions continually take place in order to maintain homeostasis between the creation of free radicals and antioxidants (Sechi et al., 2017). If that balance is altered by animals overexerting themselves, the homeostatic balance will be altered leading to an increased production in free radicals and ROS (Sechi et al., 2017). Another component that may increase or decrease the amount of oxidative stress that a dog incurs throughout their lifetime is their size (Jimenez et al., 2018).
Dog sizes can vary from small chihuahuas to extremely large mastiffs however smaller breeds have a lengthened lifespan compared to bigger dog breeds (Jimenez et al., 2018). The size of a dog is associated with their metabolic rate including mitochondrial function (Jimenez et al., 2018). Mitochondria provide a critical source of energy within cells and are most affected by oxidative damage due to ROS production taking place within mitochondrial organelles (Jimenez et al., 2018). When the mitochondria are damaged from oxidative stress, gene expression can be altered leading to structural damage (Jimenez et al., 2018). “The “oxidative stress” theory of aging states that aging is not a genetically programmed phenomenon, but it happens because of the deleterious damage of oxidative stress on the genetic machinery” (Jimenez et al., 2018). Large dog breeds experience cell turnover more frequently which may enhance their likelihood of being more prone to structural damage from oxidative stress compared to small dog breeds (Jimenez et al., 2018 This concept plays a pivotal role in the aging process of dogs (Jimenez et al., 2018). Chronic oxidative stress in large dogs may lead to increased rates of disease and an earlier mortality rate compared to smaller breeds (Jimenez et al., 2018). In this specific study, large breed dogs demonstrated a larger percentage of DNA damage compared to small breed dogs (Jimenez et al., 2018). DNA that has been damaged from oxidative stress can cause the cell lifespan to shorten from the negative impact of gene modifications (Jimenez et al., 2018). In large dog breeds, the DNA repair mechanism stops working earlier in a dog’s lifespan compared to small breeds (Jimenez et al., 2018). With an increased rate of cell turnover and a shorter period of DNA repair mechanisms, large dog breeds may be more susceptible to oxidative stress than smaller breeds (Jimenez et al., 2018). Further research is needed to measure dogs oxidative stress levels over their entire lifespan comparing small and large breed dogs and oxidative stress levels, antioxidant enzyme levels, free radicals, and ROS production. A larger sample size is also needed to incorporate medium size dogs as well and see how they compare to small and large dog breeds in their overall oxidative stress levels. Incorporating hemp products into a dog’s diet may be a preventative maintenance tool when taking action against oxidative stress as a vital component of the aging process.
Hemp seed meal protein hydrolysate (HMH) may be a possible preventative maintenance option for dogs when battling oxidative stress. HMH was able to decrease oxidative stress in hypertensive rats (Girgih et al., 2014). In this study , it was concluded that HMH reduced the rate of lipid peroxidation which caused oxidative stress leading to an overproduction of free radicals and ROS (Girgih et al., 2014). This mechanism of action decreased lipid peroxidation which lead to an increase in antioxidant enzymes in the body and a decreased oxidative stress response (Girgih et al., 2014). HMH contains specific amino acids that form peptides with the ability to “neutralize ROS in addition to preventing metal-catalyzed lipid peroxidation” (Girgih et al., 2014). This is demonstrated when HMH peptides are absorbed in the body via ingestion and block the accumulation of harmful lipid peroxides in the blood stream (Girgih et al., 2014). This will decrease the body’s exposure to toxic levels of radical compounds which will lower the risk of disease caused by free radicals (Girgih et al., 2014). When ROS levels are lowered, non-enzymatic antioxidants are protected from adhering to oxidation which will increase the number of antioxidants in the body (Atalay et al., 2019) Further research is needed on how HMH may affect dogs over their lifespan as a preventative maintenance option for oxidative stress. Other ingredients in hemp products such as cannabidiol (CBD) may be a helpful tool to have when contending oxidative stress.
CBD also plays a major role in reducing oxidative stress within the body (Atalay et al., 2019). CBD has been analyzed to contain (30-50%) more antioxidant properties compared to alpha- tocopherol or vitamin C (Atalay et al., 2019). “CBD protects lipids and proteins against oxidative damage by modulating the level of oxidative stress, which participates in cell signaling pathways” (Atalay et al., 2019). CBD will utilize the redox system which transfers electrons from free radicals and modifies them into less active molecules (Atalay et al., 2019). CBD is also involved in the Fenton Reaction through the chelation of transition metal ions which may include sodium, magnesium, copper, zinc and other metals not listed depending upon what the animal ingests over their lifetime (Atalay et al., 2019). Chelating transitional metals will decrease the creation of ROS in the body (Atalay et al., 2019). When transitional metal ions are chelated, their concentration is reduced in the body (Atalay et al., 2019). Reduced transitional metal ion concentration in the body has been demonstrated to slow down the formation of B-amyloids in neurons which is part of the aging process (Atalay et al., 2019). Hemp products containing HMH and CBD may play an essential role in dogs and all animals as they naturally accumulate oxidative stress through free radicals and ROS production as a part of the natural aging process. Currently, I was not able to find any studies associated with dogs who were treated with hemp to combat oxidative stress and what positive or negative impact that may have over their lifespan. Further research is needed to see how hemp products may affect oxidative stress levels in a dog’s body over their entire lifespan. Further research is also required to see what impact CBD or HMH will have on dogs when administered for their entire lifespan as a preventative maintenance tool.

In the animal rights movement, cruelty–free is a label for products or activities that do not harm or kill animals anywhere in the world. Products tested on animals are not considered cruelty–free, since these tests are often painful and cause the suffering and death of millions of animals every year.
Getting vegetarianism confused with veganism is a common mistake most people make. So today we are going to closely examine the definition of vegan versus the definition of a vegetarian in this post. Hopefully, this provides a little clarity.
The Oxford dictionary definition of a vegetarian is “a person who does not eat meat or does not believe in eating meat, fish, fowl, or in some cases, any food derived from animals, as eggs or cheese, but subsists on vegetables, fruits, nuts, grain etc.”
This basically divides vegetarians into two groups; vegetarians who exclude eggs and dairy and vegetarians who include these items in their diets. The latter can then be broken up into a further three groups; ovo- vegetarians (who consume eggs but not milk), lacto-vegetarians (who consume milk but not eggs) and ovo-lacto vegetarians who consume both milk and eggs.
There’s often controversy surrounding “semi-vegetarians”, whose diet consists mainly of vegetarian foods but includes fish or poultry. The main differentiating factor between all of the above-mentioned groups is how much animal products are included in the diet.
The above difference is the main distinguishing factor between the definition of vegan and that of a vegetarian because vegans exclude animal products in their entirety. The official definition of veganism is “the practice of abstaining from the use of animal products, particularly in a diet. As well as following an associated philosophy that rejects the commodity status of sentient animals.
A follower of veganism is known as a vegan”. That means veganism extends beyond the diet of a vegan individual. That is the biggest difference between vegans and vegetarians. While vegetarians may not consume animal products, they may use them if they are present in other products, such as items containing silk, honey or leather.
Vegans, on the other hand, avoid the use of animal products in all areas of their lifestyles.
Cannabis strains including Hemp and Marijuana are either pure or hybrid of the plant genus Cannabis, which encompasses the species Sativa, Indica, and Ruderalis.
Varieties are developed to intensify specific characteristics of the plant, or to differentiate the strain for the purposes of marketing or to make it more effective as a natural supplement. Variety names are typically chosen by their growers, and often reflect properties of the plant such as taste, color, smell, or the origin of the variety. These varieties have been cultivated to contain a high percentage of cannabinoids, including CBD, CBG, CBC and more. Several varieties of Cannabis, known as Hemp, have a very low THC content, and are instead grown for their fiber, seed and therapeutic propertiess
CBD has become quite popular over the last couple of years but despite what you might think it is only one of the 100 compounds that have been identified in the Cannabis Sativa L plant. Full-spectrum CBD oil, unlike CBD isolate products, includes a wide range of cannabinoids present in the cannabis or hemp plant. Depending on the condition and what you are looking to achieve it can provide a greater effect than CBD alone as all the cannabinoids work together in what is known as the entourage effect.
Full-spectrum CBD also contains a variety of essential vitamins, minerals, fatty acids, protein, chlorophyll, terpenes, flavonoids, and fiber. When referring to CBD in the hemp plant, it’s important to understand that Hemp contains a large number of cannabinoids (in trace amounts), but the main compounds are CBD and cannabidiolic acid (CBDa). As CBDa is more abundant in the hemp plant, firms must decarboxylate the oil. This process heats the oil and changes CBDa into CBD.
Just one last thing before we explain the benefits of Full Spectrum CBD oil, its important to understand that CBD from Cannabis is only legal in Medical or recreational states, while CBD hemp oil is legal in all 50 states under the 2014 US Farm Bill. While it may not be able to treat all conditions it has been known to assist with a variety of medical conditions including anxiety, depression and acute pain.
The Benefits of the Whole Plant
One of the most important studies relating to full-spectrum CBD oil took place at the Hebrew University of Jerusalem’s Hadassah School in 2015. It compared the performance of a full spectrum extract with one that contained CBD only. The study concluded that full spectrum was more effective when fighting pain and inflammation.
While CBD only is somewhat effective, the whole plant extract not only provided faster and better relief, the effects also lasted longer. This is why an increasing number of companies in the CBD industry are selling full-spectrum CBD oil as a rule.
The aforementioned entourage effect is the main reason behind the efficacy of whole plant extracts. There are over 100 ‘identified’ compounds in the cannabis plant. While most of these compounds have their own therapeutic benefit, they come together in a synergistic way to provide far better performance than any single compound, including CBD.
