KONG; consistently sturdy!
Color: bone, Size: 1 Count (Pack of 1)
This toy is small enough for my 11 pound puppy and he loves it. It's also sturdy enough (as KONG products always are) to withstand his terrier jaws and ability to destroy most toys in under 5 minutes. Keeps him busy for hours.

Wears out more quickly than standard versions
Color: bone, Size: 1 Count (Pack of 1), Color: bone, Size: 1 Count (Pack of 1)
While my puppy loved this bone and it was a good starter toy, it didn't last long. Our lab puppy loves to chew - especially when we stuffed the ends on this bone. After about 1.5 months of moderate use, she ended up chewing off and swallowing a small chunk of this bone, which she thankfully passed without issue. The material of this bone is intentionally softer than other kong toys, so it breaks down easier, and you will need to inspect it for wear more frequently. We have since upgraded to the large super chewer version for her, and she still loves it.
