Veterinarians Sound Alarm on Popular Dog Treats Causing Serious Harm
As a devoted pet owner, I used to believe that splurging on premium chews, all-natural jerky, grain-free biscuits, and fortified dental treats for my pugalier Rocky meant I was providing the best care. With Americans spending nearly $70 billion annually on pet food, I felt I was contributing to a culture of love and indulgence. However, veterinarians are now raising urgent concerns that some of the most beloved products are leading to emergency surgeries, dental issues, and organ damage in dogs.
The Hidden Dangers of Hard Chews
Dr. Stephanie Liff, a veterinarian and practice owner based in New York City, witnesses the consequences firsthand. She notes that 26% of dogs will suffer from fractured teeth, typically from chewing on hard items. The culprits are often treats owners consider safe, such as bully sticks, yak chews, antlers, and smoked bones. "Any treat that is not soft enough for you to make a dent with your nail is technically too hard and could break a tooth," Liff warns. She recently performed surgery to remove a Himalayan yak chew from a dog's stomach, and another patient, a labradoodle, cracked both large back molars on a hard chew so forcefully the owner heard it across the room, resulting in over $2,000 in repair costs.
Even experienced breeders are not immune. Katherine Bailee, from a family that has bred European Dobermans for two generations, recalls giving her Doberman, Ares, a smoked marrow bone. "Within 20 minutes, the bone splintered into shards as sharp as glass," she said. One large piece wedged horizontally across the roof of his mouth, while smaller fragments were swallowed. Ares survived, but they spent 48 hours monitoring for signs of a perforated bowel. Bailee now labels such products "a literal internal hazard," cautioning that for breeds prone to bloat and sensitive gastrointestinal tracts, the pet treat aisle can be the most dangerous place in a store.
Rawhide and Chemical Risks
Rawhide presents another significant threat, though for different reasons. Often mistaken for dried meat, it is actually a byproduct of the leather industry, processed with chemicals like bleach and hydrogen peroxide to maintain its shape. When chewed, it softens and can be swallowed in chunks, then swells in the stomach or intestines, potentially causing life-threatening blockages.
Caleb Johnstone's golden retriever, Killua, experienced this firsthand after swallowing a large chunk of a knotted rawhide bone. "The piece grew inside his stomach like a sponge and caused a serious intestinal blockage," Johnstone explained, necessitating emergency surgery. Dr. Ezra Ameis, a veterinarian and owner of Paw Priority veterinary clinic, performs gastrointestinal surgeries every few weeks to remove such items, emphasizing that these incidents are completely avoidable. He advises, "Don't give your dog anything as hard as their teeth. It can break them."
Invisible Threats: Kidney Damage and Grain-Free Diets
While injuries like fractures and blockages are visible, some treats cause damage that goes unnoticed. Dr. Jordyn Zoul, a veterinarian at Seaside Veterinary Hospital in St. Simons Island, Georgia, treated a middle-aged dog with sudden lethargy, vomiting, and loss of appetite. Blood work revealed acute kidney injury, linked to jerky treats causing Fanconi-like syndrome, a rare kidney disease. "Some recover once the treats are stopped, but others are left with permanent kidney damage," Ameis added, recommending owners avoid jerky treats altogether.
Zoul also highlights risks associated with grain-free diets, which many owners choose under the misconception that dogs are carnivores. "We have overwhelming research now that grain-free diets can lead to heart disease in dogs," she stated. Dogs are omnivores and require nutrients from plants and starches. She diagnosed a 2-year-old Rottweiler with dilated cardiomyopathy, a condition where the heart becomes enlarged and weakened, linked to a lifelong grain-free diet. After switching to a grain-inclusive diet, the dog fully recovered within a year.
Label Deception and Safer Alternatives
Beyond the contents, packaging labels pose separate issues. All three veterinarians flagged xylitol, an artificial sweetener found in some peanut butter and yogurt-based treats, as extremely dangerous, capable of causing life-threatening low blood sugar and liver failure in dogs. They also warned against ingredients like BHA, BHT, and excessive salt. Liff criticizes the term "natural" as a marketing ploy, not indicative of safety or digestibility. Ameis simplifies it: "If you can't easily identify what's in it, it's probably not a great choice."
For their own dogs, these vets opt for simplicity. Liff provides softer, single-ingredient treats, Ameis offers blueberries, carrot slices, and lean meat, and Zoul ensures treats constitute under 10% of daily calories, with supervision during chewing. They all endorse the fingernail test: if you cannot dent a treat with your nail, it is too hard for your dog.
Inspired by these insights, I have revamped Rocky's treat drawer. Smoked bones and jerky are gone, replaced by softer chews and carrot sticks. Anything with an incomprehensible ingredient list has been discarded. It is a small step to ensure the safety of my cherished companion, reflecting a broader shift toward informed and cautious pet care.
