Myself & my partner cannot thank Nik & Aleigha enough, we contacted them in July for our puppy Rottweiler Beau she was over friendly wanted to say hello to everyone was starting to pull so wanted some extra help with her.
The difference has been amazing she has learnt so much & we have as well, she absolutely loves them both, THANK YOU

Myself and my partner couldn’t thank Nik and aleigha enough for the past 8 weeks with their hard work and dedication transforming my 17month old GSD from reacting to humans, dogs and anything that moved while out walking. Have previously have 3 different trainers including boarding&training with “top places” while spending thousands with zero results, we then found NK9INE after the first few days Nik gave so much information and insight to my dogs behaviour by the first week Nik had bonded exceptionally well and we already saw changes in his behaviour with reactivity , Nik went beyond our expectations having not being able to have him off leash and enjoy/play over parks etc to now being able to have him off lead while being around other humans and dogs without reacting and even being off leash in public places which we never thought would be possible. There is so much more I could write but I’d be going on for hours.
Our 8 weeks have now came to an end and We cannot emphasise enough how grateful we are for Nik’s expertise and dedication with his passion for work you’ll be missed by Gen we have already booked in for more training and will continue to use in the future .

Myself & my husband cannot recommend NK9ine enough. We got to the point where we were dreading walking our nearly 8 stone Rottweiler due to pulling & reacting to anything & everything. Once the training started we noticed a very quick change in our daily walks. NK9ine gave us confidence, lots of helpful advise regarding how we handle different situations whilst out and changing his food to raw along with vitamins & minerals. Now we look forward to our walks and time with our very energetic and crazy dog so thank you NK9ine. More...

Walking my dog used to be a true ordeal and I dreaded it. Managing a 9-stone Rottweiler who was reactive to anything that moved—whether it had legs or wheels—completely destroyed my confidence and I could sense that he was unhappy on our walks. I contacted Nik for assistance with training and from our very first meeting, I felt enormous relief and I knew I had made the right choice.

Just eight weeks later, I have the dog I’ve always wanted. My confidence has returned, enabling me to take him out for walks at appropriate times without feeling dread. I actually look forward to some quality time walking my dog. I’ve received compliments from strangers about how well-behaved my dog is—something I once thought I would never hear. Nik has been incredibly supportive; he keeps me in the loop by sending videos and pictures of Buddy during their outings while I’m at work, which I proudly show off to my colleagues.

I cannot emphasise enough how grateful I am for Nik’s expertise and dedication. His passion for his work is evident, and it’s heart-warming to see how much my dog adores him in return. The mutual bond is a true testament to the love and attention Nik invests in to each and every training session. We’ve gained so much knowledge and skills from him, and I am genuinely thankful for the positive changes he has made.

As our training sessions are coming to an end, I’m a little sad at the thought of Buddy missing Nik. I sincerely hope we can join in some social dog walks in the future, as I know Buddy will be so happy to see him again.

Thank you Nik from Buddy and his family x

I can not rate NK9INE highly enough if stars went to 100 I would award them. Thier patience, understanding of both the dog & handler ( owner) is unsurpased. I have had several trainers/behavourist, spent a fortune on them before I bumped into him on a walk.( or should I say pull, whilst trying to hold onto a dog aggressive Staffie mix ( 3 yr old female) & an over excited high pray driven Dobberman. ( 5yr old male) After a few months due to me , And his knowledge & hard work & patience. I can now walk my Dobberman off lead, & not panic or hide from every dog I see on a walk. My walks have gone from stressful fear & years of tears to tears of pure joy when again I walked through my local woods with my Dobberman off lead. Listening to me .I continue to work with this fantastic trainer towards the day when both of my fur babies are truly brilliant k9 citizens. Which I have zero doubt will happen. So if you are looking for a peaceful, happy controlled walk with yr dog, no more looks of discust from the can't you control your dog..the its ok he/she is friendly as thier dog charges towards you..Then definitely call NK9ine More...

Cannot recommend NK9ine enough! Nik and Aleigha had my Staffy for board and train for a week whilst I was away and I can honestly see a difference in her already. NK9ine touched up on my staffys general obedience and helped with some reactivity issues she has, alongside helping her with better loose leash walking.

I was sent daily updates of my staffy and her progress and I definitely knew she was in safe hands.

Thank you NK9ine!

Having Nik step in to start training my staffie was the best thing I could of done. He not only trained my dog but also gave me great advice. I would recommend him to anyone, best thing to do. I can't thank him enough More...

We contacted Nik in regards to our Belgian Mainois, Rocko, who was a nightmare on a lead, pulling constantly, had aggression towards other dogs among many other things. During the consultation Nik explained everything throughly and answered any questions we had.
Now 4 weeks later our dog is off lead, ignoring other dogs and is finally the dog we wanted, all thanks to Nik.

Nik is genuinely brilliant and you can tell he loves what he does. The knowledge and tips he's given us is invaluable! Always prepared for the sessions, always gives a detailed overview after every session and overall a GREAT trainer! 10/10

Dog Training

Nik from NK9ine has been a brilliant trainer my dog has already turned from an unruly teenager to a lovely boy. Max was a nightmare to walk, having me over on numerous occasions but now after only 2 weeks of training he even goes into his crate without the fight we used to have. It used to take 2 of us to drag him in but now he goes in on a verbal command, Thank you Nik I was ready to give up on Max but Nik has given me real hope. More...

Wow the difference this guy has made to my dog in a week is unreal. In fact it's just 10 hours and Max resembles a good dog. I never thought I'd see my boy walking properly on the lead More...
