Hi, my name is Nikki Walden and I am the owner of Leader of the Pack

Having been animal-mad since the day I was born, I’ve always known my life would see me work closely with dogs and their owners. During my childhood and teen years I would look after and exercise other people’s dogs and horses for them. It was not until I owned my own property in my late 20s that I could finally become a dog-owner and feel complete. The pressing demands of the bills however still meant that I could not pursue a career with animals as I would have loved.


Once in my forties I was determined to make a change. I obtained my dog psychology qualification and also completed advanced training in Jan Fennell’s ‘Dog Listener’ methods. I later finally achieved my personal goal of training at the Dog Psychology Centre in L.A. with Cesar Millan (The Dog Whisperer). Through working with Cesar I also gained access to further training possibilities and have since studied a number of times with international dog training expert Brian Agnew.

With the necessary veterinary endorsements of my practice, I also obtained Professional Membership of the International Association of Canine Professionals (IACP), I am at long last able to work with the closest things to my heart – dogs and people!

Nikki has been very good at helping me with my reactive, rescue Labrador. She has great knowledge and understanding of the dogs and is very pleasant and easy to talk to. She helped me to understand my dog's behaviour and gave me ways to deal with it. I now have the confidence to be able to help him going forwards. Many thanks to Nikki (and her helper, Laura). I thoroughly recommend her.
