Pets can have behaviour issues that originate from many different experiences in their past, present and occasionally in their genetic make up. When you bring a new pet into your home, especially a rescued pet, this can also cause initial or continuing issues with your other pets.
Some pets become phobic or excessively fearful about doing particular things or hearing certain sounds. All species have their biological nature, however they too experience trauma, illness, fear, confusion, abandonment and other emotional states, in their own individual way. It is possible to de-stress and change behaviour of the vast majority of pets quickly, when they communicate the reasons of why and when the behaviour began.
