Are Pork Ears Safe for Dogs? Four Definitions Decide

Pork ears can be safe for some healthy adult dogs when the portion fits the dog’s calorie allowance, the chew bends slightly and remains larger than the dog can swallow, the product has traceable pathogen controls, and an adult supervises from start to cleanup. They are a poor choice for gulpers and dogs on fat-restricted diets. The World Small Animal Veterinary Association (WSAVA) lists 242 calories in one 2-ounce dried pig’s ear, while the FDA has documented pig-ear samples positive for Salmonella.

Pork ears and pig ears are the same treat: dried or otherwise processed porcine ear tissue. The useful question is whether a specific ear is nutritionally, mechanically, dentally and microbiologically safe for a specific dog. I prefer those four definitions because “safe” as one undivided label hides the denominator every time.

What does “safe” mean for a pork ear?

A safe pork ear has to clear four separate tests. Passing one cannot compensate for failing another.

• Nutritional safety means the weighed portion fits among all treats, toppers and table food without displacing the dog’s complete and balanced diet.
• Mechanical safety means the dog gnaws the chew instead of gulping it, and the remaining piece never becomes swallowable whole.
• Dental safety means the individual ear yields under pressure. Drying, thickness and hard edges vary, even within one bag.
• Microbiological safety depends on processing, handling and lot control. A clean ingredient list does not reveal whether a kill step worked or whether the chew was contaminated afterward.

This is why the familiar pig ears for dogs pros and cons list is usually unsatisfying. A single-ingredient chew can provide focused chewing and enrichment, yet the same ear can exceed a small dog’s treat allowance, break into a dangerous piece or carry bacteria.

How many calories and how much fat are in a pig ear?

WSAVA’s guide Feeding Treats to Your Dog gives the clearest whole-ear reference: a 2-ounce (56-gram) dried pig’s ear contains 242 calories. That is a reference portion, not a universal ear weight. Natural ears vary, so a package sold by count needs to be weighed before its calories can be calculated.

The label matters too. Brutus & Barnaby’s current whole Pig Ears specification lists 133.2 calories per ounce and 23.6% crude fat. Its own calorie explainer correctly says calories per individual ear are not listed. At that energy density, a 10-gram portion supplies about 47 calories; the arithmetic comes from the manufacturer’s 4,700-kcal-per-kilogram figure.

“Crude fat” needs its definition. AAFCO says the standard guaranteed analysis reports a minimum percentage of crude fat by product weight, and “crude” refers to the analytical method. It is neither the percentage of calories from fat nor a promise that every pig-ear brand contains 23.6%. Compare the calorie statement and guaranteed analysis from the same product.

Body weight changes the verdict. WSAVA’s calorie table places an average healthy adult dog weighing 22 pounds (10 kilograms) at 470–590 calories per day. Its treat guidance says extras should remain below 10% of daily intake, leaving less than 47–59 calories for all treats. A 242-calorie whole ear does not fit that day’s allowance. A weighed 10-gram piece may fit if no other extras are given and the dog’s veterinarian agrees with the daily target.

How often can dogs eat pig ears, then? Mighty Paw’s current product FAQ says one to two times per week. That is a manufacturer’s general direction, not a veterinary calorie prescription. For the 22-pound example, a whole 2-ounce ear is oversized even if offered only once a week.

Can pig ears choke a dog or cause an intestinal blockage?

Yes. “Digestible” describes whether tissue can be broken down; it does not guarantee that a large swallowed fragment will pass safely. AAHA identifies choking and intestinal blockage as potential chew complications and advises choosing a chew larger than the dog’s snout and slightly wider than the mouth. Power chewers that tear and gulp deserve a different form of enrichment.

Pig ears create irregular remnants. They soften with saliva, then may fold, tear or leave a thick cartilage section. Length alone is a weak control because a broad, flexible piece can be folded and swallowed. Remove the chew as soon as the remaining portion can fit entirely inside the dog’s mouth, when a chunk separates, or when gnawing changes to repeated attempts to swallow.

There is no evidence-based remnant length that makes every pig ear safe. For comparison, Bully Sticks Direct tells owners to remove bully-stick pieces under 2 inches. That number suits a cylindrical stick and supplies a useful hard stop, but it cannot describe every flat ear. For a pig ear, swallowability should end the session sooner than any ruler does.

The Merck Veterinary Manual lists excessive drooling, gagging, difficulty swallowing, regurgitation and repeated attempts to swallow as signs of an esophageal foreign body; lethargy can appear with a chronic obstruction. Those signs after chewing require prompt veterinary care. Impaired breathing is an emergency.

What does the Salmonella evidence say about pig ears?

FDA testing has demonstrated pig-ear contamination as an exposure route. In its final update on the 2019 multistate outbreak, the FDA reported 154 human infections across 34 states and 35 hospitalizations associated with exposure to pig-ear pet treats. The Michigan Department of Agriculture and Rural Development tested samples collected from Pet Supplies Plus and found Salmonella London, Typhimurium, Newport and Infantis.

Those results apply to the tested products and outbreak, not to every ear now on a shelf. The FDA eventually stopped recommending complete avoidance of pig ears as the outbreak subsided. It continued to advise supplier pathogen controls, regular testing, prevention of contamination after processing and careful handling by consumers.

The same agency traced some implicated ears to Argentina, Brazil and Colombia, while another recalled product was sourced in the United States. Country of origin is useful traceability data, but it is not a negative Salmonella test. I would choose a sealed, lot-coded package from a manufacturer willing to name its processing and testing controls over an anonymous ear from a mixed bulk bin.

FDA handling advice is direct: supervise the chew, pick it up when the dog finishes, keep it away from small children, clean contacted surfaces, wash hands, and prevent the dog from licking people or household surfaces immediately afterward. During the outbreak, 27 illnesses occurred in children younger than 5 years. Households with young children, older adults or immunocompromised people have a lower tolerance for this exposure.

Are pig ears safer than bully sticks?

Neither chew is universally safer. Pig ears and bully sticks differ in calorie density, shape and typical failure mode; the dog’s chewing style decides which difference matters. A moderate gnawer may work gradually across a broad ear. A gulper may fold that ear. A dog that methodically softens a bully stick may handle it well, while another tries to swallow the final slick nub.

| Property | Pig ear | Bully stick | What to decide | | --- | --- | --- | --- | | Representative label calories | Brutus & Barnaby lists 133.2 kcal/oz for whole pig ears | The same company lists 99.2 kcal/oz for natural bully sticks | Weigh the offered portion; neither label gives a reliable universal “per chew” number | | Representative crude fat | 23.6% on that pig-ear specification | 1.0% on that bully-stick specification | These are product-specific guaranteed analyses, not category averages | | Fragment behavior | A flat ear may soften, fold and tear into uneven pieces | A cylinder becomes shorter and can leave a compact, slippery end | Choose against the way your dog gulps, strips or gnaws | | Hardness | A thin ear often bends sooner, though a dried rim or thick cartilage can resist | A dense or thick stick often resists longer | Apply AAHA’s thumbnail and bending tests to the actual chew; discard one that cannot be indented or flexed slightly | | Sourcing | Processing country and supplier vary by package | Cattle source and processing country also vary by package | Require a manufacturer, lot code, country disclosure and an answer about pathogen controls |

The calorie comparison is real but narrow. It comes from two current specifications from one manufacturer. A separate peer-reviewed study by Lisa Freeman, Nicol Janecko and J. Scott Weese tested five bully sticks for nutrition and found an average of 88 calories per treat, with a 45–133 range. The mean stick was 5.71 inches long. That small sample demonstrates variation; it does not establish today’s calorie count for the stick in your hand.

Sourcing labels can be specific without settling safety. Redbarn’s current Natural Pig Ears page names Canada, Mexico and South Korea as origins; its Bully Stick page lists Paraguay, Brazil, Colombia, New Zealand, Peru and Turkey.

Which dogs should skip pig ears?

Skip pig ears when the dog has a history of swallowing chews in large pieces, guarding objects so they cannot be retrieved safely, cracked teeth, painful dental disease, or a prescribed diet that excludes pork or high-fat extras. Dogs with previous pancreatitis need an individual veterinary decision; the Merck Veterinary Manual identifies dietary indiscretion as a common risk factor in dogs.

Weight management is another clear stop when the portion cannot fit the calorie plan. The 242-calorie WSAVA reference ear is more than half of the lower daily energy estimate for a 22-pound dog. Smaller ears do not solve aggressive gulping, and softer ears do not erase bacterial handling risk.

For puppies, seniors and dogs with gastrointestinal disease, the answer depends on teeth, chewing behavior and the medical diet. A blanket age cutoff would pretend those dogs are interchangeable. Ask the veterinarian who knows the dog and bring the exact package, calorie statement and guaranteed analysis.

How can you give a pork ear more safely?

1. Check the product and recall status

Choose a sealed package with a named manufacturer, lot code, country of origin and calorie statement. Ask how the company controls Salmonella and check the FDA recall database for that brand and lot. Avoid damaged packaging and mixed bulk bins with no traceable lot.

2. Set the portion by weight

Use the package’s kcal/kg or kcal/oz value and a kitchen scale. Compare the result with the veterinarian-approved daily calorie target, counting every extra. WSAVA’s below-10% rule is a ceiling. If the math requires a small portion, divide the ear before giving it rather than wrestling away a softened piece later.

3. Supervise the dog’s chewing style

Offer the ear in a quiet place and stay close enough to intervene. Watch whether the dog scrapes and gnaws or folds, strips and gulps. End the session if a large flap tears free, the ear becomes swallowable, the dog tries to bolt it, or the chew fails AAHA’s thumbnail and bending tests.

4. Remove the remnant and clean the contact area

Trade the remnant for a small piece of the dog’s regular food; do not chase or force the jaw open. Discard the chew securely. Wash hands with soap and water, clean the floor or mat, and keep the dog from licking faces and surfaces immediately afterward, following FDA handling advice.

Frequently asked questions

Are pig ears bad for dogs?

Pig ears are unsuitable for some dogs rather than inherently bad for every dog. A whole 2-ounce dried ear carries 242 calories in WSAVA’s guide, and any ear can present choking, tooth or bacterial hazards. A veterinarian should assess dogs with pancreatitis history, dental disease, weight concerns or gulping behavior.

Are pig ears hard to digest?

Pig-ear tissue is edible, but “digestible” does not mean a swallowed piece cannot obstruct the esophagus or intestine. Dogs that chew it into small, softened amounts may tolerate it; gulpers may not. Remove the ear once it can fit inside the mouth. Drooling, gagging, regurgitation or repeated swallowing requires prompt veterinary care.

How often can dogs eat pig ears?

There is no universal evidence-based weekly count. Mighty Paw’s product guidance says one to two times per week, while WSAVA limits all treats to less than 10% of daily calories. For a 22-pound dog, WSAVA’s 242-calorie reference ear exceeds the entire daily treat allowance, even when offered only weekly.

Can pig ears cause a blockage in dogs?

Yes. A dog can swallow a folded ear or torn cartilage fragment large enough to lodge in the esophagus or intestine. AAHA lists intestinal blockage and choking among chew complications. The Merck Veterinary Manual identifies drooling, gagging, regurgitation and repeated swallowing as esophageal foreign-body signs requiring prompt veterinary attention.

Are pork ears safer than bully sticks?

Safety depends on the product and chewing style. Pig ears can fold or tear; bully sticks can leave a short, slippery nub. Representative Brutus & Barnaby specifications list 133.2 kcal/oz for pig ears and 99.2 kcal/oz for bully sticks. Test actual hardness, verify sourcing and supervise either chew.

Do vets recommend pig ears for dogs?

Veterinary guidance does not endorse pig ears as a category. WSAVA warns that contaminated pig ears can transmit pathogens, and AAHA flags bacterial, choking, blockage and tooth risks across chews. A veterinarian may still approve a traceable product and measured portion for a healthy dog that chews slowly under supervision.
