Happy Dog Sano N review
We don't put a score on this food. It is a veterinary diet, formulated for a diagnosed condition and meant to be fed on a vet's advice. Your vet has seen your dog and we have not, so a number from us could only pull you towards their advice or away from it, and neither of those is ours to do. What follows is what the label declares, what the analysis works out at, and where to buy it, with no judgement attached to any of it.
Happy Dog sells Sano N through its dietetic line. It is a maize and rice kibble built around a deliberately low protein level, with potassium and salt declared on the list, for dogs whose feeding plan is set by a vet.
Happy Dog's dietetic kibble, built around a low protein level, and one we do not score. Protein is declared at 12.5%, converting to 13.6% of dry matter, and that low figure is the whole design. Potassium chloride and sodium chloride are printed side by side on the list.
Our view
Likely to suit
- A dog whose vet has set a restricted protein plan
- Owners who want each trace element dosed on the panel
- Households watching egg, which is declared plainly at 4%
- Dogs of any size, with one recipe across the range
Worth watching
- Meat meal and poultry fat do not name the animal, so the list will not clear a dog avoiding one meat
- Salmon meal and beef fat put fish and beef in the bag
