Are Weight Loss Drugs Like Ozempic Dangerous for Your Pet

3/15/2026By Ivan Nikolic
Ozempic, Wegovy, and other GLP-1 medications have become one of the biggest pharmaceutical revolutions of recent years. Millions of people worldwide use these drugs to regulate blood sugar and lose body weight. But as the popularity of these medications explodes in households, a new and serious concern is emerging — what happens when a pet accidentally comes into contact with them? What Are GLP-1 Drugs and Why Are They So Popular GLP-1 agonists such as semaglutide — the active substance in Ozempic and Wegovy — work by mimicking a hormone that regulates appetite and blood sugar levels. In humans they cause a feeling of fullness, slow stomach emptying, and reduce appetite leading to weight loss. The popularity of these medications means they are now present in an ever-growing number of households — which means they are increasingly accessible to pets. What Happens When a Dog or Cat Ingests Ozempic Pen injection devices are particularly dangerous because dogs and cats can easily chew and swallow them along with the remaining medication in the cartridge. Symptoms of toxicity in pets include vomiting and diarrhoea which can be severe and prolonged, low blood sugar which can lead to weakness, trembling, and loss of consciousness, lethargy and general weakness, and refusal to eat. Small dogs and cats are particularly sensitive because even small amounts of the drug can cause serious symptoms due to differences in body weight. Medications Used for Obesity in Pets Interestingly veterinary medicine is developing its own versions of these drugs. Capromorelin sold under the name Entyce has been approved by the FDA for stimulating appetite in dogs. Research is also underway on GLP-1 agonists specifically formulated for dogs and cats that could help address obesity which is a significant problem in pets. It is estimated that more than 50 percent of dogs in the US are obese or overweight which is a direct risk factor for diabetes, arthritis, and heart disease. How to Protect Your Pet Store all medications including pen injection devices in places inaccessible to pets — in locked cabinets or on high shelves. Never leave used pen injectors in accessible locations as residual medication may remain inside. If you notice your pet has eaten or played with a pen injector call your veterinarian or emergency veterinary line immediately. Do not wait for symptoms to appear as prompt intervention can prevent serious complications. When to Go to the Veterinarian If you suspect your pet has come into contact with Ozempic or a similar medication do not wait. Call your veterinarian immediately even if there are no visible symptoms because blood sugar can drop gradually. Bring the medication with you or photograph the name of the active substance so the veterinarian knows exactly what they are dealing with.
