Great product
Size: 1 Count (Pack of 10)
My dog loves these pigs ears, she's a 20 lb Shih Tzu Jack Russell mix, I cut the ears in half but they're still going within 10 minutes.

Not the same as the last shipment
Size: 1 Count (Pack of 10)
I have always thought these were great but this time they were black. Didn't look fresh. Don't know if I will buy again.

The Best for My Furry Friend
Flavor Name: Pig Ears, Size: 12 Count (Pack of 1)
As a pet owner who always seeks the best for my furry friend, I decided to try out the Scott Pet GRILLERZ Pig Ears 12CT, and I must say, they have exceeded my expectations.
**Quality and Flavor:**
The pig ears come in a pack of twelve, and each ear is substantial in size and weight, indicating a high-quality product. My dog was instantly attracted to the aroma and flavor. Unlike some other treats, these pig ears are roasted to perfection, ensuring a rich and savory taste that my dog can't get enough of.
**Health Benefits:**
One of the standout features of Scott Pet GRILLERZ Pig Ears is their natural composition. They are free from artificial preservatives, flavors, and colors, making them a healthy and safe option for my dog. Additionally, these treats help promote dental health by reducing plaque and tartar buildup as my dog chews on them.
**Longevity:**
These pig ears are long-lasting, providing my dog with hours of enjoyment. This is particularly beneficial for keeping him occupied and mentally stimulated, which is crucial for his overall well-being. I have found that one ear can keep my dog entertained for a significant amount of time, making it a cost-effective treat option.
**Packaging:**
The packaging is sturdy and resealable, ensuring the treats remain fresh between uses. This is a thoughtful touch that I appreciate, as it maintains the quality of the product over time.
**Price:**
Considering the quality and quantity of the pig ears, the price point is quite reasonable. It offers great value for money, especially when compared to other similar products on the market.
**Conclusion:**
Overall, the Scott Pet GRILLERZ Pig Ears 12CT are a fantastic choice for any dog owner looking to provide their pet with a delicious and healthy treat. The quality, flavor, and health benefits make it a top-notch product that I highly recommend. My dog loves them, and I am confident that your pet will too!

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.
