Our expert says:
I suspect that you JRT is expressing normal behavior by licking the other animals ears.
Grooming is an essential form of communication between animals in addition to keeping the animals ears clean.
Sometimes this behavior is aberrant such as the behaviors expressed in a condition called compulsive canine disorder - if this is the case then your JRT may require training/medication to resolve the problem - please discuss this with the website's behaviourist.
