'Hypoallergenic' is doing a lot of unearned work on dog food shelves: the term has no legal definition in UK pet food, so by itself it guarantees precisely nothing. In practice it usually signals that a recipe leaves out the ingredients that most commonly trigger reactions - often chicken, beef, dairy, wheat or soya. That is a sensible starting point for many itchy or troubled dogs, but it is not the same as allergen-free, and it is certainly not a diagnosis.

The useful version of this category is the one you build yourself: identify what your dog reacts to, then choose foods that verifiably exclude it. That is where clear labelling becomes everything. A food that names exactly which proteins it contains beats one hiding behind 'meat and animal derivatives' - which could contain almost any animal protein and defeats the entire purpose of an exclusion diet.
For confirmed allergies, properly run elimination trials and hydrolysed-protein diets exist, and they are vet-led tools. This is label analysis, not veterinary advice. If your dog has a health condition, talk to your vet before switching foods. Below: every food carrying hypoallergenic claims, scored /100, ingredients fully broken down.
Less than you would hope. The term has no legal definition in UK pet food, so it is a signal of intent rather than a guarantee - usually meaning the recipe avoids common triggers such as chicken, beef, dairy or wheat. Whether it avoids the thing your dog actually reacts to is a different question entirely, and the ingredients list answers it.
Animal proteins top the list of confirmed triggers - chicken, beef and dairy most often - with wheat and soya appearing less frequently. That surprises owners taught to blame grain first. It also explains why novel-protein recipes built on duck, venison or insect exist: the point is avoiding proteins your dog has already met and reacted to.
Only if food was the cause, and often it is not - fleas, environmental allergies such as pollen and dust mites, and skin conditions all cause itching too. If a food reaction is suspected, a properly run elimination diet is how it gets confirmed. Persistent itching deserves a vet conversation before a long career of expensive food-hopping.
Food where the protein is broken into pieces so small the immune system struggles to recognise and react to them - the heavy artillery of allergy feeding, generally used in vet-led elimination trials or for confirmed multi-allergen dogs. It is expensive and specific, so it is not the everyday answer for a mildly itchy dog. Talk to your vet first.
