These are awesome, they are definitely for smaller dogs, puppies, or light chewers. I thought they were super cute and I am surprised my Siberian Husky puppy didn't rip this apart the first day he got it. Super cute I recomend them for smaller dogs and puppies for sure.

I have a small dog and use these for snacks, I used to keep them in plastic bags, these are clearly better. Now when I whip them out, my dog gets all excited lol. Super easy to throw in a bag and go to the dog park with.

My poms love these!  Great for small dogs,  They measure 3 inches as stated and I put a bit of peanut butter or cheap dollar store potted meat inside the shoe for an extra treat.  I will by again!

Anyone who wonders what is the difference between the small/medium and the large/extra-large, need wonder no longer. They are exactly the same except the rope on the "smaller" one is about 1/16 of an inch smaller in diameter. Otherwise they are exactly the same so save the $3.00 and get the "smaller" one. My dog loves this toy and it lasts for a couple of weeks before the antler is all chewed away.

UPDATE: DON'T BUY THESE this addendum is written 2 months after buying these for my dogs. I was very surprised to see these chewed into small shards, several of which are easily small enough to swallow and were needle sharp. I originally gave these 5 stars because my dogs love them. I have downgraded that to one star because I think my vet might love them (help with his mortgage payment?). See second photo

I got these not from amazon but from a local pet store and I must say I absolutely love them! And my pup pup does to. Don't be afraid to get these for bigger dogs! My baby girl is 50lbs and these are great for training. They are the perfect little treat. (Pro tip: read the inside of the box For a good laugh!)

My dogs absolutely loved these!  The mini treats were really easy for my small dogs to eat.  Everytime they hear that bag opening they come a runnin'.  I usually have to cut up the bigger treats for my smaller dogs,  but these mini treats are the perfect size.  Which means no waiting for treats.  As soon as that bag is open,  they can dig right in.

PROS: Easier for small dogs to squeak or catch, fun to throw for dogs to chase, and relatively safe for throwing in the house.
CONS: Dogs that intend to destroy these will have any easy time doing so.

My dog (12 lb shih-tzu/pomeranian mix) absolutely loves these. She basically only plays with plush toys that squeak, but her little mouth is too small to squeak most toys on her own. However, with these she figured out that she could make them squeak by pressing them toward the ground.
Now she goes crazy over these. When I give her a new one it instantly becomes her favorite toy. If I have to take it away she whines for it and then searches for it. She's never been as obsessed over any of her other favorite toys as she gets with these.
ONLY PROBLEM:
One of these eggs used to last her quite a while, sometimes many months, and then the squeaker would stop working, probably from punctures. That was a great lifespan for the price. But one day she decided that as fun as these were to play with, they were more fun to destroy. And so she did. And she never forgot. The last 2 that I gave her lasted maybe 30-45 minutes each. I'm keeping it at 5 stars because it's not the toys fault my dog wants to destroy them now, she didn't used to. If I give her a durable toy she won't touch it, she only likes plush. What can you do?

CONCLUSION:
If your dog is small, attracted to plush toys that squeak and likes to chase them, he/she will probably love these.
A larger dog will probably puncture the squeaker faster. And any dog that likes to intentionally tear holes in plush toys and remove the stuffing will have quick success. If you're not sure, just try it. It's cheap enough.

So happy about these senior version Kongs!!!!!!!! I have super seniors one of which has barely any teeth and these are much softer than the regular red ones which are too much for my pups. They are still very sturdy though. I got a few size smalls for my dogs who are between 8-12 lbs and its the perfect size since they're not big chewers just lickers to get the treats out. If your dog highly likes chewing and our around their size Id get a medium.

I bought 2 for our little pooches and used one to take my cat to the vet.  These are fantastic!!!  They're the perfect size for our small dogs and have the expansion features to provide additional room.  When not needed, the expansion areas can be used as storage pockets, too.  The carriers also fold down easily for storage.  We haven't used them on a plane trip yet, so really hope they'll fit under the seats as promised.

my dog absolutely adores these. Good for little dogs with small teeth that don't do well with very hard chews etc

An awesome product for a small dog who is too big for puppy collars, yet too small for regular small dog collars.

So, I personally feel as though these ears are much too small for any dog over 40 lbs. Some ears are less than 4"x1", and others might be 6"x1.5". Also, my dogs (75lbs boxer mix and a 65lbs shepherd mix) go through an ear in under 10 minutes - sometimes less than 5.

With that in mind, the dogs, especially the shepherd, LOVE them. I've offered previously loved cow ears that are now flat out rejected because they know I've got a bag of lamb ears in the same closet. The shepherd, who is normally nonchalant about treats and chews, has taken to pestering me non-stop and all-day. She's literally grabbed my shirt and started tugging to get my attention (not good behavior, and never before seen from her at all). Once I'm up, both dogs dash for the pantry where the lamb ears are kept and literally start drooling.

As obnoxious and annoying as they've become, I'll admit, I will keep buying these in bulk. They are just so thrilled, and enjoy them so much. And the price is quite reasonable when compared to other bulk ears and the dogs' affinity for them. No leftovers here...ever.

My dog loves them yet I don't consider this chews are for small breeds. I have a poodle and I have to break each chew in three parts.

Got these for my two little dogs (a Yorkie/Jack Russel/Rat Terrier mix and Border Terrier) - they love them!

I'm a huge fan of the giant knuckle bones, which keep my big dogs busy. for some reason, I thought these would be a little larger than they are. They are under 3" .... dogs still got some time out of them, but would probably be better for smaller dogs (under 40 lbs).

These sweaters are only for small dogs, make sure your measurements are correct!
These are super adorable, I bought two, one in gray, the other in light blue. I got a medium size for my 5 lb. Yorkie, and it fits perfectly, there's even a little room. The quality is great for the price, although the gray and the blue that I received feel different. The gray one is so soft, I love how it feels. The blue one is thicker, and slightly stiffer, but still good.

These are VERY tiny not even a 1/2" long. Great for dogs under  7lbs. Or to do treat training with bigger dogs - you may make them chew it & not swallow it. The cadet brand products are really great, I would recommend anything they make. Beware these are very tiny. Like little chips. They are too small for me, but I'm giving them to a friend with 7 chihuahuas all under 5lbs  it will be perfect for her. It was delivered within 3 business days.
