Cow ears are a popular dog chew that most healthy dogs can enjoy in moderation. They are dried cartilage with a little skin, they do not splinter like cooked bones, and they last longer than many treats. They also carry real risks: choking, intestinal blockage, extra calories, and bacteria such as Salmonella. Supervise your dog every time.
What Are Cow Ears?
Cow ears are the dried outer ears of cattle, sold whole or sliced, plain or with hair left on. The chew is mostly cartilage, which is why it is crunchy and takes time to eat. Because it is an animal product, quality varies a lot by brand and country of origin.
Possible Benefits
- Dental scraping. Long chewing can help scrape soft plaque off teeth, though it does not replace brushing.
- Mental stimulation. A chew gives dogs something to do, which can help with boredom and teething.
- Easier than rawhide for some dogs. Cow ears are softer than bully sticks or hooves, so they can suit seniors with sensitive teeth. Note that they are usually still a treat, not a joint supplement, so do not rely on them to treat arthritis.
Risks to Know About
- Choking and blockage. Dogs that gulp large pieces can choke, or swallowed chunks can block the intestines. Take away the last small piece.
- Calories and fat. Cow ears are lower in fat than pig ears but are still calorie-dense. Count them as part of the daily treat allowance, no more than about 10 percent of daily calories.
- Bacteria. The CDC and FDA have linked pig ear treats to Salmonella infections in people and dogs. Wash your hands after handling any animal chew and keep it away from children.
- Stomach upset. Rich chews can cause loose stool or vomiting, especially in dogs prone to pancreatitis. Ask your vet before giving them to a dog with a history of it.
How to Choose and Serve Safely
- Pick a size larger than your dog can swallow whole.
- Buy from a brand that lists the country of origin and ingredients, and avoid treats with added dyes or sugar.
- Stay with your dog while they chew, and throw the ear away if it breaks into sharp pieces or smells off.
- Give a chew only occasionally, not every day.

Bottom Line
Cow ears can be an occasional chew for healthy adult dogs when you supervise and choose a size that cannot be swallowed whole. Skip them for dogs that gulp, have pancreatitis, or are overweight. This is general information, so check with your veterinarian about what is right for your dog.
