I have noticed my female besingi mix (18months) of age becoming more and more agressively towards me, children, and other dogs. She is very well socialized however she is becoming more dominant, wanting to nip at faces agressively when playing with dogs who too want to attack playfully at the face. However, she has become very aggressively to mommy when trying to keep her outside while I vacuum and she absolutely hates the vaccum and having the door shut closing her off from me. SHe tried to bite my arm (very agressive face with fangs out and fur up) last week and I had to use a broom in order to shut the door. Additionally, she snarls at children. Khloe and I are the only 2 in my household, so no kids and no one else. Only few friends and neighbors stop by but lately she is getting even more aggressive towards them, even if she knows them. I do not know what to do. We were kicked out of puppy training when she was 4 months old b/c she has severe leash aggression. She does work well with a clicker, but I dont always have the clicker on me. My vet today told me to come on here to see if you guys could potentially help or lead me to the right direction of contacting an animal behavioralist. He stated Khloe will only get worse if nothing is done. Additionally, I do not spank Khloe, I only use a clicker, but obviously does not show her that I am the dominant one. SHe also demands all of my time to the light up laser for hours on end and will not give up. Please help!
