Royal Canin made my pups loose, could only get away with using it mixed at 25% to 75% other.
No such issues with Arden Grange Prestige or Puppy.
I am sure others will have opposing views, it so much depends on what agrees with your dogs.
The Royal Canin made my adults loose,s o I should not have been surprised, but I wanted to use up the food I had won, and bought the puppy with vouchers from a good win.
Price wise on the breeders scheme Arden Grange comes off better, and more importantly is less expensive for new puppy owners.
