A lot of people buy Kongs. I however don't anymore. I have had several dogs since Kongs were invented and exactly NONE of them have liked Kongs.
Siren likes her "Chilly Bone". (Got it at either Petco or Petsmart.) You get them wet and then freeze them. Some folks just use a wash cloth and do the same thing, then let the pup chew on it. I always end up with pups that would rather pull the strings out of the wash cloth one at a time and either eat them or leave them all over the carpet.
I thought about getting a "Cuz" since it seems that a LOT of dogs on the board have them and love them. But once I squeeked one at the store, I IMMEDIATELY changed my mind. If I had to listen to THAT squeeking I would LOOSE MY MIND.
If you are going to get things that squeek, I would squeek it about a dozen times as fast as you can FIRST. Because that is what MY pups like to do. Some sounds don't bother me, others....... I would rather stick bamboo shoots under my fingernails than listen to them.
