Small but mighty
Color: Chew Pair, Size: Mini (Pack of 2)
Dusty (chihuahua) loves the blue bone! It is the perfect size for his little mouth and he loves that he can put it to the back of his mouth and just chew on it. The rope one is his least favorite as it appears to be too big for his mouth. They’re great quality and while they are not stretchy they do bounce!

The only toys my older Chihuahua likes
Color: Chew Pair, Size: Mini (Pack of 2)
These are the only toys my older Chihuahua likes. They can't be found locally, Thank goodness I can order them and get them here fast.
My younger Chihuahua grabs them sometimes and chews big chunks off. Swallowing the chunks would be a concern

Good but watch for the strings coming undone.
Color: Chew Pair, Size: Mini (Pack of 2)
Our 12 week old puppy has loved chewing on these bones. The only issue you'll need to look out for is the knots in the strings come undone very easily. I've had to retire them multiple times. This could be dangerous for dogs that like to eat strings!!

Not as I expected
Color: Chew Pair, Size: Mini (Pack of 2)
The chew pair is so small. It looks more like it is for a hamster than for a small dog of almost any size. What a waste of money!
