    Healthy, natural treat my dogs actually love—no mess!
    Flavor Name: Pig Ears, Size: 12 Count (Pack of 1), Flavor Name: Pig Ears, Size: 12 Count (Pack of 1)
    These pig ears are the perfect natural alternative to rawhide. All three of my dogs go crazy for them, and I feel good giving them a single-ingredient treat. What I used them for: Occasional chew treats for my three dogs. Pros: Single-ingredient, natural treat Dogs love the taste and texture Doesn’t stain or leave a mess despite slobber Good size for medium to large dogs Cons: Can be a bit odorous out of the bag (minor) Real experience: I’ve given these to all three dogs multiple times, and each one enjoys them equally. Unlike some rawhide or flavored chews, these don’t leave stains or get mushy—cleanup is easy, which I really appreciate. Comparison: Much healthier and cleaner than rawhide chews or flavored alternatives, but still keeps dogs occupied for a similar amount of time. Final verdict: If you want a natural, low-mess chew for dogs who love to gnaw, these pig ears are a solid choice.

    Nice Enough for the price!
    Flavor Name: Pig Ears, Size: 12 Count (Pack of 1), Flavor Name: Pig Ears, Size: 12 Count (Pack of 1)
    Good price, not all are big though. But, they look like nice pigs ears and we got 13 instead of 12 (Oliver is eating one as I type so it’s not include in my pic, lol). I will order another bag fr his Christmas gift to share with his dog buddies.

    Yummy pigs ear
    Flavor Name: Pig Ears, Size: 12 Count (Pack of 1)
    These are my dogs "special" treat. These range in size from large to small ears but my dog loves them all the same. Great for heavy chewers.

    One-and-done treat for giant breeds (our 186lb foster approves)
    Flavor Name: Pig Ears, Size: 12 Count (Pack of 1), Flavor Name: Pig Ears, Size: 12 Count (Pack of 1)
    We foster a 186lb Saint Bernard, and finding treats that actually satisfy her without requiring half the bag has been a challenge. These pig ears? Game changer. What makes these work: - ONE ear = one satisfied dog (compared to other treats where the bag says “35 per day” and she’d still beg for more) - Keeps her busy for about 5 minutes of focused chewing - She does a little excited dance when she sees the bag—can’t even sit, just wiggles - Zero crumbs or mess because she devours every single bit, then spends the next hour sniffing around hoping another one appears - She immediately grabs it and heads to her favorite bed to settle in—doesn’t move until it’s gone The only “issue”: There’s a bit of oil/greasiness when handling them, but nothing a quick hand wash can’t fix (Mrs. Meyer’s Cucumber soap works great, just saying). Bottom line: If you have a giant breed and you’re tired of buying treats that require multiple servings or disappear in one bite, these are it. One ear, complete satisfaction, Subscribe & Save so they just show up like a present you forgot you ordered. Our girl Ellie gives them 186 pounds of approval.

    Size of Ears is Inconsistent
    Flavor Name: Pig Ears, Size: 12 Count (Pack of 1)
    A bit disappointing with the size, 1 large pig ear, the rest small and not actual whole pig ears. But Doggo enjoys them. No problems with digestion for him.
