Horses Often Adept At Hiding Dental Pain

Though most horse owners and caretakers will investigate a horse's mouth for pain if he's refusing to eat his feed entirely, equines often offer other clues that their mouths may hurt, reports EQUUS magazine.

Scientists from the University of Helsinki surveyed the owners of 47 horses that had cheek teeth surgically removed because of root infections. Tooth root infections can be caused by several things, but most of these removals were the result of dental fractures.

The survey asked 23 questions of these owners regarding horse behavior. Respondents noted that the behaviors that were eliminated after the surgical tooth extraction included dropping hay, eating slowly and adjusting hay in the mouth while chewing.

Before surgery, horses with dental pain often avoided the bit, raising their heads or getting “behind” the bit to avoid contact. Painful horses also behaved more antisocially toward people and horses. All of these behaviors dissipated when the painful tooth was removed.

Dr. Jaana Pehkonen, lead researcher, said that avoiding the bit was the most common indicator that something was amiss. She notes that this may be because this behavior is easiest to notice.

In half the study horses, tooth infections were not discovered until a routine dental exam took place, indicating that many owners miss behaviors that can be linked to dental pain. Only six of the 47 horses had obvious signs of tooth issues like external swellings or sinus drainage. Nearly all the owners said that their horses were more comfortable after the teeth were removed.

Pehkonen concluded that some equine behaviors, like self-mutilation, aggressive behavior or withdrawnness aren't regarded as pain behaviors by horse owners. However, once the pain is removed and the horse returns to acting “normal,” it's easier to see that the behaviors indicated discomfort. Pehkonen recommends horses have annual dental exams so that any problems can be identified.

Study Indicates Bitless Bridles Not Necessarily Better Than Snaffles When It Comes To Equine Welfare

Some riders believe that riding a horse without a bit is kinder than traditional bitted options, but new research suggests this may not be the case. Results of a new study show bitless bridles can cause as much pain and pressure on the horse's face as a traditional noseband might, according to The Horse.

Tracy Bye with the University Centre Bishop Burton in Yorkshire, and student Nina Robinson used five university-owned horses in a study using three types of bridles: a bridle with a snaffle bit and regular noseband, a cross-under bitless bridle, and a sidepull bitless bridle. The nosebands on the bitless bridles were fitted to manufacturer instructions and the bridle with the snaffle was tightened to the “two finger” rule.

[Story Continues Below]

Each bridle was fitted with pressure sensors under the crown piece and the noseband. The horses were worked for 30 minutes per day, three days in a row with the same rider, with each type of bridle.

The scientists found that the average amount of pressure on the nose was 65 percent higher with a sidepull bitless bridle than a snaffle-bit bridle. The cross-under bitless bridle had pressure that was 11 percent higher than a snaffle bridle. Compared to the snaffle, peak pressure on the nasal bones were 147 percent higher with the sidepull and 109 percent higher with the cross-under bridle compared with the snaffle.

Though peak pressures were high, they were not sustained, so it's unclear if they would cause damage. The team found that each noseband created pressure as high as that recommended for a tourniquet in human medicine. The scientists also noted that horses ridden in a cross-under bridle tended to hold their heads higher with their necks extended, which could contribute to back pain and poor performance.

The team concluded that the different styles merely transfer the pressure to other areas of the face. The ideal welfare solution may be teaching riders to use their hands differently rather than switch to any one particular type of equipment.

World Horse Welfare-Funded Research Project Seeks To Keep Horse Sport Ethical

World Horse Welfare strongly believes in the value and benefits of the horse-human partnership and actively supports the participation of horses in sport as long as their welfare is put first. Against the backdrop of increasing societal concerns about the involvement of horses in competitive sport, and with the aim of underwriting equestrian sport's continued social license, World Horse Welfare initiated this research project with the Royal Veterinary College. The project is especially relevant in light of the heightened public interest around equine welfare, sparked by recent events such as the incident at the women's Modern Pentathlon at the Tokyo Olympics and this summer's Panorama documentary, “The Dark Side of Racing.”

The first phase of the project was led by Dr. Madeleine Campbell, Senior Lecturer in Human-Animal Interactions & Ethics at the Royal Veterinary College. Phase 1 covered the theory and function of the ethical framework. Campbell also leads Phase 2, which will begin in October 2021 and continue for three years. This phase focuses on optimizing the function and uptake of the ethical framework tool. It aims to extend the scope and significance of this project's impact on welfare by advancing the applicability and uptake of the framework across the equestrian sports sector.

[Story Continues Below]

To achieve the project's broader aims, the specific objectives are:

  1. To refine the ethical framework tool following the final phase of testing in the preceding project and develop a tutorial explaining how to use it
  2. To test the applicability of the ethical framework tool at a grassroots level
  3. To investigate socio-cognitive drivers, facilitators and barriers to adoption of the ethical framework tool in practice, and to develop effective methods of overcoming such barriers and promoting adoption
  4. To conduct systematic reviews of evidence relating to two discipline-specific, stakeholder-identified ethical dilemmas in order to identify research priorities targeted at improving welfare through promoting evidence-based use of the framework

Roly Owers, Chief Executive Officer, commented, “We are delighted to support this project into its second phase, which aligns so closely with a key aspect of our 2020-2024 strategy: 'Supporting the ethical involvement of equines in sport and entertainment.' As recent events such as the infamous Gordon Eliot photo and the treatment of horses during Modern Pentathlon at the Tokyo Olympics have shown, this work has never been more relevant and we are excited to be a part of this pioneering development.

“Working together with equestrian sport and its regulators is an essential part of our work to help achieve the best possible welfare standards and practices throughout the whole lives of sport horses. We are pleased that, in line with this approach, the project will make particular use of stakeholder consultation, building on the results of the October conference and conducting further testing and consultation with equestrian organizations as we progress with the project over the next three years.”

Dr. Madeleine Campbell, Senior Lecturer in Human-Animal Interactions & Ethics at the Royal Veterinary College, commented, “We are looking forward to testing this tool with further decision-makers across all levels of horse sport and we hope the workshop engages everyone in discussion around what exactly needs to be considered when making policies that can impact upon horse welfare. The framework in itself does not tell any stakeholder what conclusion they ought to be reaching on any particular issue – it simply provides them with a logical method of reaching some conclusion based on a set of guiding principles.  This means that the framework tool can be used in any setting within equestrian sport to facilitate the transparent, consistent justification of decision and policy making.”

On Nov. 11, 2021, “Whose opinion matters?” will be the theme of World Horse Welfare's annual conference, which is being held both virtually and in person at The Royal Geographical Society, London. The Conference will bring together influential figures in the industry and will address the increasing challenge of distinguishing key voices at a time when the sheer volume of strong opinions on welfare can be overwhelming and deafening. The event will consider the role of objective evidence in decision making and when – if ever – opinion should overrule fact. The RVC research project will be particularly relevant to the Conference in light of these themes.

Stronach Group To Ban Owners And Trainers Who Ship Horses Via Cargo Ship, Citing Welfare Concerns

1/ST Racing Chief Operating Officer Aidan Butler distributed the following letter to racing connections at facilities owned by The Stronach Group on Aug. 17. The movement of horses via cargo ship has recently become a topic of discussion in the equine welfare community, as it has been the chosen method of transport for some entities moving horses from the mainland United States to Puerto Rico. 

To Our Valued Owners, Trainers and Connections,

At 1/ST RACING, one of our top priorities is to protect the welfare and safety of horses that train and race at our venues. We believe this duty of care extends to horses during their racing careers and beyond, as they leave our facilities to race and train elsewhere or to retire.

As part of 1/ST RACING's ongoing and steadfast commitment to achieving the highest standard of horse care and safety in Thoroughbred racing, we reviewed the shipment of horses via cargo ship to race and train in other parts of the world. In consultation with our Chief Veterinary Officer, Dr. Dionne Benson, we have determined that the conditions in which these horses are transported via cargo ship are inappropriate, inhumane and represent a significant risk to their health and welfare.

Accordingly, effective immediately, any trainer or owner who is associated with shipping horses via cargo ship will no longer be welcome at any of our training or racing facilities. Trainers and owners shipping horses are responsible for performing the required due diligence to ensure horses in their care are transported in safety by humane methods.

Failure to prevent the shipping of horses via cargo ship will result in the immediate removal of the associated owner or trainer's horses from any, and all, 1/ST RACING venues.

I have communicated with the horsemen's groups in each of our jurisdictions in California, Florida and Maryland and have received their full support on this issue. If you have any questions regarding this policy, please connect with me directly via email at aidan.butler@1st.com. As industry stakeholders, it is our collective responsibility to protect these amazing athletes and we thank you for your joint commitment to their health and welfare.

–Aidan Butler
