Picky dog approved!
Flavor Name: Boy, Size: 8 Count (Pack of 1), Flavor Name: Boy, Size: 8 Count (Pack of 1)
My elder beagle generally doesn’t like cookie or biscuit type of treats. He prefers soft bacon types. I ordered these for his doggy 12 year birthday so his attending “friends” could all share the treats. I wasn’t expecting him to eat it, but wanted the set for the occasion. He took a sniff and immediately took the treat and ate it. He loved it as did the other dogs (one of those also a “picky treat eater” All of the dogs loved them. I will definitely be ordering again for special occasions.

Pretty but crumbled to bits.
Flavor Name: Boy, Size: 8 Count (Pack of 1)
These birthday doggy bones were pretty to look at and they smelled good. However, each bone was tightly shrink wrapped and very difficult to open. Not one came out whole and most just crumbled so thoroughly there wasn’t a piece big enough to hand to my dog. So, not a win.
