The Frequency is 37.5 KHz which is on the Low Frequency LF band 30khz -300khz

NO.

This is SOUND, not radio. This is ultrasonic, i.e. you can't hear it. Your dog can though. This is a SOUND on the low end of what boats use for depth-finding and sonar.

Species Approximate Range (Hz) human 64-23,000 dog 67-45,000 cat 45-64,000
