Review of Scientific Research Dog Studies and Cloves
Due to the purported benefits to dog’s health and antibacterial nature of cloves (similar to tea tree oil) scientists have undertaken some studies on the beneficial effects of cloves.
- In a scientific journal article in Pharmanutrition scientists evaluated the anti-inflammatory and antipyretic properties of clove oil in dogs. So thirty adult male dogs were used. After a surgical incision on the abdominal area, animals were divided into four group. The first group received 25 mg/kg of clove oil while the second group was considered as a control and the other groups were provided various pharmaceutical. Interestingly, the scientists determined that:
- Clove oil treatment in dogs after surgery decreased the number of white blood cells such as neutrophils.
- Rectal temperature significantly decreased in the clove oil-treated group as compared to control after surgery.
- Clove oil-treatment significantly reduced the number of inflammatory cells in surgical area as compared to control after surgery reducing oxidative damage.
- Clove oil administration has anti-inflammatory and antipyretic properties in dogs after surgery.
- In another study published in the Archives of Animal Nutrition scientists aimed to produce dog food containing natural antioxidants (blend of blend of essential oils from clove, rosemary, oregano, and vitamin E) to replace synthetic antioxidants and determine the effects on food conservation and animal health sequentially. The foods were produced in a commercial factory, and the antioxidants were added at the oil bath stage. Ten adult beagle dogs were used, divided into two treatments; control treatment (CON; synthetic antioxidant feed [butylhydroxytoluene]) and test treatment (NAT; natural antioxidant feed; blend of essential oils from clove, rosemary, oregano, and vitamin E).
- It was concluded that natural antioxidants in dog feed, in addition to promoting feed conservation, stimulate levels of systemic antioxidants and minimize the impacts caused by free radicals in the dogs’ blood.
- In another study, published in the world small animal congress from 2007 researchers attempted to assess the ability of cloves to reduce fever in dogs. 16 adult male mixed dogs, weighing 15-20 kg, were selected and observed for three weeks to assess their general health. Then, after general anesthesia and preparation of the dogs, and following an experimental surgery, 12 dogs that had developed fever without administration of antibiotics, were randomly divided into four groups, each of three dogs. The first group was injected by clove oil 10 mg /kg, the second group by acetaminophen 10 mg/kg, the third by clove oil 20 mg/kg, and the last group (control group) by normal saline 2 ml. Each 5 minutes, for three succeeding hours, their temperature was measured rectally by a digital thermometer.
- The results of this study, revealed that clove oil has a specific antipyretic in balancing the natural temperature of body and even once injected in double dose to the febrile dogs its effects are comparable to standard acetaminophen.
Benefits of Cloves for Dogs
Cloves have many benefits for humans and dogs as the scientific studies clearly show. Although cloves contain a considerable amount of volatile oily essence that some thought to be dangerous to dogs science shows that cloves can be used as energizer, appetite stimulant, disinfectant of wounds, alleviate fever, recover from surgery.
Many people also use cloves to combat bad breath and to put on a tooth ache. In fact when dentistry was not readily available people were known to pack a tooth with a clove to remedy severe cases of tooth issues.
How Many Cloves Can Cause Serious Danger For Your Dog?
How many cloves your pet may consume without serious danger depends upon the age and bodyweight of your dog. Generally, a dog would need to consume a high doses of cloves before anything can happen.
If we look at the scientific studies where cloves were used for their beneficial effects the dogs received between 10 and 20 ml of concentrated clove oil. According to the Asian Pacific Tropical Journal, a science journal that studied clove oil, concentrations up to 18% of essential oil can be found in the clove flower buds. Roughly, 89% of the clove essential oil is eugenol and 5% to 15% is eugenol acetate and β-cariofileno.
Accordingly, if your adult dog consumes small doses like one or two cloves it should not be cause to worry as that little will not put your dog at risk. Although few cloves are enough to cause toxic effects in puppies.
Make sure you keep away any food products that contain cloves or clove oil away from puppies and if puppies do get into cloves you should call the pet poison helpline as the risk of toxicity to puppies is far greater.
Many pet owners simply desire to stay on the safe side and avoid cloves altogether despite the beneficial effects, which is understandable.
What Happens to Dogs That Consume Too Many Cloves?
If your dog does consume too many cloves or, far more likely too much concentrated clove oil, they may suffer upset stomach, gastrointestinal tract distress and resulting high blood pressure which are signs that your dog may be suffering from clove toxicity these symptoms may progress to include irregular heartbeat (arrhythmia), low body temperature, difficulty breathing, vomiting, nervous dysfunction affecting the hind limbs due to the effect on the nervous system, and even death.
However, again your dog would have to have consumed a large amount of cloves. Numerous scientific studies show that many dogs receive concentrated amount of cloves with beneficial effects.
Eating cloves for dogs is a topic still under debate. Many pet owners do not think feeding cloves is a good idea and instead just elect to play it safe and avoid cloves altogether while simply avoiding such foods that dogs don’t generally eat anyway.
Even though there are many beneficial effects from cloves many still you can’t overlook the risk of liver damage. Added to this that the sensitivity level of every dog is different if feeding cloves to one dog proved beneficial it may not work for every individual. In the end, it is best advised to feed recommended foods to your pets so they can live healthy lives and always consult a veterinarian if your pet is showing signs of toxicity and keep the dental chews to some greenies for dog dental care as opposed to cloves to avoid serious problems.
