Generally speaking, most dogs like toys that simulate prey. This is why squeaky toys and soft toys are often very popular with most dogs. Hearing the high-pitched squeak and/or ripping apart a soft plush toy can be immensely satisfying to some dogs.

Why do dogs go crazy for squeakers?

Animalistic instinct

Similarly to how wolves choose their prey, dogs prefer toys that can be torn apart, smell like something they can eat, or make noise. That squeaking sound may be annoying to us, but to our pets, it resembles the sound of a scared or injured animal, which activates their hunting instinct.

Why does my dog cry for the squeaker?

Whatever the reason behind the crying, this behavior has its roots in your dog's ancestral dynamics geared towards hunting small squeaky animals or birds. The squeaky sound may just alert a desire to protect the squeaking toy from anyone else.
