Food sensitivities are one of the few problems where changing the bowl genuinely changes the outcome — and one of the most common reasons owners start reading ingredient panels properly.
This page is written for owners in California weighing up freeze-dried raw. The nutrition below holds wherever you live — what changes locally is delivery, not diet — so we would rather give you the substance than pad it with things we cannot actually verify about your city.
What improvement looks like, and when
Itching and skin usually settle over two to four weeks. Digestion often moves faster. Coat is last, because you are waiting on new growth rather than repairing what is there — four to six weeks is normal.
If nothing has shifted by eight weeks on a strict trial, the trigger is probably not dietary and it is worth asking your vet about environmental causes.
How an elimination trial works
Feed a single novel protein and nothing else — no treats, no scraps, no flavored medication — for eight to twelve weeks, then reintroduce one ingredient at a time.
Most trials fail not because the food was wrong but because something else got into the dog. The discipline is the hard part, not the diet.
What a food allergy actually is
A true food allergy is an immune response to a specific protein. It is less common than owners assume; most diet-related trouble is intolerance, which is digestive rather than immune.
The distinction matters less than it sounds, because the fix is the same: identify the ingredient and remove it. That is far easier with a short, named ingredient list than with a recipe blending several proteins.
Treats are where most diets quietly fail
A careful bowl and an uncontrolled treat jar cancel out. Most commercial treats carry several proteins, wheat and flavorings, any of which can be the thing you are trying to isolate.
During any trial, treats should be single-ingredient and the same protein as the food, or absent.
You are not paying to ship water
Fresh refrigerated food is roughly three-quarters water by weight, and that water is chilled, boxed with coolant and driven to your door on a schedule.
Freeze-drying removes it before shipping. No refrigeration, no thawing, no freezer shelf, no delivery window — and if you want the moisture back, it comes free from your own tap.
Reading a label without being misled
Guaranteed analysis is printed “as fed”, so it includes the food's moisture. A dry food and a wet food cannot have their protein percentages compared directly.
Convert to dry matter first: divide the protein percentage by the dry matter percentage, where dry matter is 100 minus moisture. A canned food at 10% protein and 75% moisture is 40% protein on a dry basis — higher than a kibble showing 30%.
Single protein, and why it matters practically
Every Loyal Saints bag contains one named animal protein — Beef, Chicken, or Turkey with Salmon.
Beyond ingredient purity, this has a practical consequence: if your dog reacts to something, a single-protein food lets you identify what it was. A recipe blending several proteins makes an elimination trial close to impossible.
Getting the interval right
A 14 oz bag is about 7.8 cups. Divide by your dog's daily amount to get the days per bag, then set the delivery interval slightly shorter so you are never scraping the bottom.
Common questions
Is chicken a common allergen?
It is among the more frequently reported, along with beef and dairy — largely because those are what dogs eat most.
Do I need a prescription diet?
Sometimes, for hydrolyzed protein trials. Many dogs do just as well on a clean single-protein food. Ask your vet which applies.
Can dog food allergies appear suddenly?
Yes. Allergies develop through repeated exposure, so a dog can react to a protein it has eaten for years.
