Personalised nutrition for better dog health

It is a little-known fact that we human beings owe our understanding of our nutritional needs, to dogs. And just as those scientific studies established the nutritional needs of we humans, more recent studies have proven beyond doubt that our two species have shared the same diet for thousands of years.

It is with this unique understanding of both canine and human nutrition that Canine Nutritionist can improve the health of client dogs with personalised nutrition. Since most dog health problems are gut-related, whether your dog is suffering from allergies or arthritis, ear infections or pancreatitis, it makes sense to work with a team who understand gut health and how to improve it holistically through dietary means.

With an unrivalled knowledge of the history of dog nutrition, Canine Nutritionist has worked with clients all over the world, helping to improve the health of their dogs with research-based dietary knowledge.

We provide expert, science-backed nutrition advice, personalised diet plans and bespoke therapeutic recipes for both healthy puppies and adult dogs as well as dogs with various health conditions including:

 Trustindex verifies that the original source of the review is Google. I decided to contact Gerald after we had made a trip to the vets for our little dog, he has always brought up bile in the mornings after eating grass but had started to bring his food back up. We were given meds and some suggestions were made about having a camera put down his throat and a hydrolysed diet was also mentioned. Our older dog is on cooked food after buying Gerald’s guides, but our little dog was always so picky with his food so he was on commercial food as that’s all he seemed to eat. After a week of being on the elimination diet he is doing so much better. Gerald also made some other suggestions to help, we wouldn’t hesitate to reach out for a consultation if that was needed. I’m so glad I’m came across him and would highly recommend to all of my friends that have dogs 😊 here a photo of Bertie after climbing Snowdon

 Trustindex verifies that the original source of the review is Google. Gerald is AMAZING. He properly read the lengthy history I sent him about our dog, gave us sensible, research-based advice, was reassuring and helpful, and answered all our questions. We now feel we have a positive way forward with our dog after years of food difficulties and associated health problems. I would recommend Gerald in a heartbeat.

 Trustindex verifies that the original source of the review is Google. Gerald has been a knowledgeable, kind, and most helpful guide as I try to deal with my sweet dog’s chronic enteropathy. None of the solutions my vets have offered have helped (prescription diet, antibiotics, prednisone) but I was lucky enough to be referred to Gerald by a friend who raved about the success she’s had following Gerald’s nutritional advice for her dog. For us, so far so good with the nutritional and supplement changes & my dog’s spirits have improved.

Gerald has an outstanding website with tons of information; however, I’m so glad I booked a consultation with him to talk specifics about my dog’s situation.

For anyone outside the UK who might be hesitant about setting up / conducting the consult — not to worry. Gerald made it easy to schedule & there were no technical issues when we held the call.

It is very reassuring to have Gerald in our corner. Highly recommend him!

 Trustindex verifies that the original source of the review is Google. We booked the New Puppy Guidance Consultation for our 10 week old Working Golden Retriever Puppy.
From the first enquiry to the consultation everything was professional, thorough and timely.
We received a wealth of information and guidance around transitioning from a kibble diet to a fresh food diet,  along with further health guidance and support.
We have begun implementing this advice and seen improvements in bowel movements as well as behaviours.
The follow up advice was also thorough, informative and helpful, reflecting what had been discussed during the consultation along with further relevant information.
We would not hesitate to use the Canine Nutritionist again if required in the future, and have found the whole experience from start to finish extremely positive and invaluable.

Thank for you everything.
Louise and Danny

 Trustindex verifies that the original source of the review is Google. Gerald, the canine nutritionist, has been absolutely amazing to work with! When Phoebe started having some issues with weight loss and scooting and itching, our vet recommended I seek a Canine nutritionist (and also several medication options which I wasn’t happy to keep covering symptoms). I had found him months previously and purchased the fresh food diet guide and knew the quality of his advice and professionalism! I wholeheartedly request and consultation and boy am I glad I did! Just a week into his recommended elimination diet and she is already so much happier! And, I have been able to reach back out with further questions and he is happy to answer and so friendly and easy to chat with!!  Thank you so much!

 Trustindex verifies that the original source of the review is Google. We’ve been working with Gerald for Cairo’s nutrition, and I honestly can’t recommend him enough.
Cairo has quite complex needs, and Gerald has taken the time to really look at him as a whole, not just what he’s eating, but how that’s impacting his overall health and wellbeing. His knowledge is incredible, but what really stands out is how much he genuinely cares.
Everything has been explained clearly, adjustments have been thoughtful and tailored, and we’ve always felt fully supported throughout the process. You can tell this isn’t just a job to him, he truly wants the best for the dogs he works with.
We’re already seeing positive changes, and I feel so much more confident in how we’re supporting Cairo moving forward. Thank you again!

 Trustindex verifies that the original source of the review is Google. Gerald is - quite literally - a life saver. My precious Lurcher was slipping away from me after months of increasingly severe dietary issues which were perplexing her vets. One questionnaire and follow-up consultation with Gerald and she was on the road to recovery and has not looked back. I can't recommend him highly enough, his advice is life-changing as well as life-saving. Don't hesitate,  contact him today. Your precious friend will thank you for it.

 Trustindex verifies that the original source of the review is Google. As a dog professional, I sought Gerald’s expertise because I needed a clear, structured plan for my younger dog. While I have completed courses in canine nutrition and make a conscious effort to stay up to date, the field evolves rapidly—and with social media saturated with “miracle” products and conflicting advice, even those with knowledge can find it overwhelming.

Gerald was exceptional. He responded promptly, and within just a few emails we had arranged a phone consultation for the very next day.

What truly sets Gerald apart is not only his depth of knowledge, but his kindness and generosity with his time and advice. He took the time to listen carefully to all of my dog’s quirks, quickly understood the underlying issues, and provided thoughtful, practical options and solutions tailored to our situation.

Thanks to Gerald, I now have a clear, trustworthy plan of action—and most importantly, confidence in the path forward to support my dog’s health.

Thank you so much, Gerald!
