Cow Ears: Safety & Feeding Guide for Dogs

Cow Ears: Safety Upfront

Yes, cow ears are generally safe for dogs. They are a popular, natural, single-ingredient chew derived from the outer ear of cattle. Cow ears consist primarily of cartilage and skin.

They are highly digestible, making them a much safer alternative to processed rawhide, which often causes serious gastrointestinal issues. Cow ears are often considered a healthier, lower-fat, and less greasy alternative to pig ears or high-fat processed treats. Safety depends heavily on the quality, source, and, crucially, supervision during chewing.

Key Takeaways & Benefits

Natural chews like cow ears offer several distinct advantages over synthetic or highly processed alternatives. They satisfy a dog’s innate need to chew while providing nutritional benefits.

Natural & Low-Calorie

Cow ears are a natural source of protein and fiber, offering a wholesome chewing experience. Importantly, they are significantly lower in fat and calories compared to pig ears, making them a better choice for dogs prone to weight gain or those requiring a low-fat diet. A typical cow ear contains around 50–70 calories, depending on the size.

Highly Digestible

Unlike processed rawhide, which is chemically treated and can swell significantly in the stomach, cow ears are generally highly digestible. This rapid breakdown reduces the risk of serious gastrointestinal blockages, which is a major concern with many other long-lasting chews. The cartilage and connective tissue are easily broken down by canine digestive enzymes.

Dental Health

The chewy, slightly tough texture of the cow ear helps scrape plaque and tartar from the surface of the teeth as the dog chews. This mechanical action contributes positively to oral hygiene. Furthermore, the act of chewing satisfies natural canine instincts, reducing boredom and destructive chewing behavior directed at household items.

Suitable for Most Dogs

Cow ears are appropriate for almost all breeds and sizes, from small terriers to large mastiffs. They are often suitable for puppies as well, provided they are monitored closely. Their relative softness compared to hard bones or antlers makes them a good choice for dogs with sensitive teeth or older dogs.

Safe Feeding Checklist

Ensuring the safety of cow ears requires careful selection and strict adherence to feeding guidelines. Treating them as a supplement, not a staple, is key to preventing health issues.

Source Check

Only purchase cow ears from reputable sources that clearly state their processing methods. Ideally, look for products labeled as single-ingredient, free from harsh chemicals, bleaches, or artificial preservatives. Minimal processing, often involving simple drying or baking, ensures the chew remains natural and safe. Avoid products with excessive smoke flavoring or added colorants.

Portion Control

Cow ears are treats and should not replace a balanced meal. They contribute calories and should be factored into your dog’s daily intake. Reduce regular food portions on days a cow ear is given to prevent excessive weight gain. For most dogs, one cow ear should be limited to a single chewing session.

Supervision

Always supervise your dog while they chew any treat, including cow ears. Supervision is mandatory to prevent choking or the swallowing of large, unchewed pieces. If a dog attempts to gulp the chew or breaks off a large chunk, intervene immediately.

Remove Small Pieces

The greatest risk associated with cow ears is the final, small piece. When the cow ear is chewed down to a small, easily swallowed piece—about the size of a postage stamp or smaller—remove it immediately. This prevents the small piece from becoming a choking hazard or causing an obstruction in the esophagus or stomach.

Monitor Digestion

After introducing a new chew, observe your dog for the next 12–24 hours. Look for signs of digestive upset, such as vomiting, diarrhea, excessive gas, or lethargy. If your dog has a sensitive stomach, introduce the chew slowly, perhaps allowing only 10–15 minutes of chewing time initially.

Risks & When to See a Vet

While cow ears are generally safe, they are not without potential risks, primarily related to ingestion habits and product quality. Understanding these risks helps owners mitigate potential dangers.

Choking Hazard

The primary risk is swallowing the final, small piece whole, which can lead to choking or obstruction. Dogs often become highly motivated to finish the treat when it is nearly gone, leading to hurried ingestion. Supervision is mandatory until the chew is removed. If a dog is a known "gulper," cow ears may not be the best choice.

Bacterial Contamination

Like all animal products, low-quality cow ears that have not been properly cleaned, dried, or stored can harbor harmful bacteria, such as Salmonella or E. coli. Choose products that are clearly sourced and processed in facilities that adhere to high hygiene standards. Always wash your hands after handling the chew.

Digestive Upset

While highly digestible, giving too many cow ears, or introducing them too quickly, can overwhelm a dog’s digestive system. This is especially true for dogs with sensitive stomachs. Temporary side effects may include soft stool, diarrhea, or mild vomiting. If these symptoms persist, discontinue use.

When to Seek Veterinary Care

Immediate veterinary attention is required if you suspect an obstruction or severe illness. Signs of a serious problem include:

• Persistent vomiting (especially if attempting to vomit but nothing comes up, which can indicate bloat or a high obstruction).
• Severe lethargy or weakness, indicating systemic distress.
• Abdominal pain or bloating, often accompanied by restlessness or inability to get comfortable.
• Inability to pass stool 24 hours after swallowing a large piece, suggesting a blockage in the lower GI tract.

Cow Ear Alternatives (Lower Risk)

For owners concerned about the choking risk associated with the final piece of a cow ear, or for dogs that are aggressive chewers, several safer, highly digestible alternatives exist.

Bully sticks are often considered the gold standard for safety because they are entirely digestible and break down into soft pieces rather than sharp shards. Yak chews are extremely durable and, when chewed down to a small nub, can be microwaved into a safe, crunchy puff, eliminating the choking hazard. Veterinary-approved dental chews offer guaranteed safety and specific health benefits.
