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.

Just what the pet parent ordered
Flavor Name: Pig Ears, Size: 12 Count (Pack of 1)
As a furbaby parent of 2 huskies who are chewers in their first 3 yrs of their life, this product helps a lot. Very healthy, dogs love them, safe, and chewy. Definitely a winner. Love the price for my pockets. Give it a try, you won't be disappointed and your pup will thank you too.

Smell of plastic
Flavor Name: Pig Ears, Size: 12 Count (Pack of 1)
These had a very off-putting smell right out of the bag - each one smelled like plastic, almost as if they’d been sitting in the packaging for too long. My dog wouldn’t touch them at all, which says everything. Would not purchase again.

AWESOME HEALTHY DENTAL TREATS for any dog.
Pattern Name: Half Ears (40-pack)
THESE ARE AWESOME!! Though I need to cut these pig ears with an industrial pair of sheers (cutting scissors), my three 6 lb Chihuahuas LOVE these treats. It also keeps them busy chewing so daddy can get some work done. They are most importantly great for cleaning my dogs tiny Chihuahua teeth. 😁😉. These are a MUST BUY for anyone seeking a healthy, affordable, teeth-cleaning option for any size dog.

Dogs enjoy them
Pattern Name: Half Ears (15-pack)
The brand I usually get them was not available at this time from Amazon and my other retailer only had large white cow ears, which don't look appealing to me even though my schnoodle is in the with knawing on them , the sound of him taking them apart in bed in the middle of the night is something to wake up to. So I was glad to have this recommended as a substitute, and they look like they are flavor to them,the are on assorted sizes and the dogs seem to like them and in the long run that's all that matters
