Humans often lead, and their dogs typically follow – this principle may now apply to weight-loss medications. Medications such as Wegovy have become common among those seeking to lose weight swiftly. However, businesses are exploring the science behind these weight-loss injections and the potential applications for our four-legged friends, who could be next to receive a slimming solution.
The active ingredients in these drugs imitate a hormone called GLP-1, which reduces appetite. A biotech firm has announced trials of an implant that targets dogs and aims to bring it to market by 2028 or 2029. The hope is that this science can curb the voracious appetites of certain dog breeds, leading to weight management.
While experts agree that such medications can be beneficial for overweight animals, there are concerns and potential for controversy regarding their use outside of the human population. The issue of pet obesity is prevalent for many owners, contributing factors being neutering, age, stationary lifestyles, and overfeeding. UK Pet Food reports that 50% of dogs and 43% of cats are overweight. Excess weight can shorten the lifespan and reduce the quality of life of pets. Overweight cats, for example, are at a greater risk of diabetes, urinary tract issues, and cancer. Overweight dogs often face health challenges like arthritis, heart disease, breathing problems, and cancer.
Veterinarians usually recommend increased exercise and strict prescription diets as solutions. Dr. Eleanor Raffan, a veterinary surgeon specializing in canine genetics and obesity, suggests that exercising discipline should be the first step. She advises owners to modify their dog’s diet and exercise routine to manage weight gain.
If this does not work, she sees no issue with using drugs mimicking GLP-1 if tested in well-designed clinical trials.
Michael Klotsman, the CEO of a company developing a long-acting implant, OKV-119, says this treatment can help differentiate between a normal appetite and weight-related behaviors. The aim is to have pets eat appropriate portions without food obsession.
Yet there is a concern that appetite suppressants can hide indicators of a pet’s health since appetite is often an essential sign. If a pet’s appetite decreases due to medication rather than illness, owners may struggle to notice other problems.
Researchers like Prof Peter Sandøe suggest trying other solutions before opting for medical interventions, including activity feeders, extra walks, treatment controlled feeders, and replacing treats with toys and games. The medical solution is just one tool and should be considered in the broader context of the well-being of both animal and human.
