Lorna Bennett from Kidlington wrote on Facebook about her Labrador Holly-Boo with our Max Strength Joint Supplement,

"She has a really beautiful soft coat but more importantly her energy levels have risen tenfold and she can run, play and jump with the best of them. Its like her mojo has returned and it is absolutely brilliant to see the transformation".



As did Heather Fielding from North Wales and our Nourish + C Multi Vitamin and Mineral Supplement, talking about her Shih Tzu Ted. She says, 

" I have found that her skin has improved tenfold something my vet couldn’t even do. I have also found a huge improvement in both my dogs poo. I highly recommend this product and give it 5+ stars".




Pamela McCaughey from Warwick writes about her Collie Bertie on The Good Vet and Pet Guide

"An excellent product and excellent customer service. . . . . 

We have now been giving him Nourish + C and we are over the moon, our furry boy is back to his old self doing all things collie, long walk, game, 5 mins rest, more ball, what time is my next walk :) , his fur is incredible and we have had so many compliments as to how well and young he looks again. Thank you Winston and Porter for both your excellent product and clearly your care and passion for what you do".



Excellent dog nutrition is at the heart of our products. Our Multi Vitamin and Mineral and Dog Joint Supplements are very effective and probably one of the best you can buy anywhere for your dogs. This is because of the Unique Essential Ingredients included at High Levels and they contain NO Buffers or fillers; just full of Goodness!

Our supplement range is suitable for all dogs from the very smallest, to the very biggest. They are excellent for performance dogs like working and sports dogs.

Julie Hill, International Sheepdog Trial Champion endorses our Nourish + C Max Strength Dog Joint Supplement

“I have recently introduced Winston & Porter’s Nourish + C Max Strength Joint Supplement to some of my ageing working dogs. Just after two weeks I noticed improvement to flexibility and movement in my dogs.

The ground they work is steep and rugged, an unsympathetic environment that causes stress and strains to the dog’s physiques. I definitely will be continuing to use this quality product and recommend it to others.”


Julie Hill, Neth Hill Border Collies

Stan Rawlinson, dog behaviourist endorses Winston and Porter Dog Supplements

Stan Rawlinson AKA 'The Original Dog Listener' recommends our products.


Stan is an honest no nonsense type of person and he is well respected within the canine behavoural world. He says,


"As you may see on my website I do not have many recommendations or adverts on my site. I would have to really be bowled over before I recommend any product. . . . . "  

Denwyn Border Collies, Wale endorse Winston and Porter Dog Supplements

Janine Rees-Denman, Border Collie trainer and professional breeder at Denwyn Border Collies says about our Nourish + C Puppy Porridge, 

"Nourish C Puppy Porridge is the best whelping feed I have used to date.
Having working border collies in my kennels that have to be in excellent working condition after having pups, this product kept mum to be in top condition ready for whelping. A huge plus was no scouring and my litter had the best start!
