Limited-Ingredient & Novel-Protein Diets

Single-Source Proteins • Novel Meats • The 12-Week Food Trial & Rotational Feeding

The Quick Version: 'My dog or cat is itchy or has a sensitive tummy—what food should we try?' is one of the most common questions on our floor! While environmental triggers (fleas, pollen, dust) are common, switching to a single animal protein your pet has never eaten before ('novel protein') with matching single-ingredient treats for about 12 weeks is the cleanest way to test whether a food ingredient is the culprit.

2. Two Ways That Work — Pick What Fits Your Home

Stocked Across All 6 Stores (Salem Pet Supply)

Step 1: Audit Every Protein Your Pet Eats Now (Including Treats!)

What is 'novel' depends 100% on your pet's own history—duck is only novel to a dog that hasn't eaten duck:

Option A

Check Your Purchase History at the Register

Can't remember every bag your dog or cat has tried over the last two years? Just ask our crew—we can look up your past food purchases right in our register system!

Option B

Read the Fine Print on Current Kibble, Cans & Chews

Many 'Salmon' or 'Lamb' foods still use chicken fat, chicken meal, or egg further down the ingredient panel. Flip the bag over and check the whole list together.

Step 2: Pick Between Limited-Ingredient (L.I.D.) & True Novel Protein

We shelve our sensitive-diet dog foods in two clear sections so they are easy to compare:

Option A

Limited-Ingredient Diets (Familiar Meats, Short Ingredient List)

Pairs a single animal protein (such as Salmon, Lamb, Duck, or Turkey) with simple carbohydrates like sweet potato, pumpkin, oats, or brown rice—skipping multi-meat blends.

Option B

Novel-Protein Diets (Venison, Kangaroo, Bison, Rabbit, Quail, Goat)

Uses less common meats your pet has likely never encountered, such as Zignature (Kangaroo, Venison, Goat, Guinea Fowl, Trout), PureVita Venison, or Natural Balance Venison/Bison.

Step 3: The 12-Week Food Trial vs. Everyday Rotational Feeding

Know which strategy you're running right now—because they have opposite rules!

Option A

During a 12-Week Food Trial: Strictly One Protein Only

As Hill's notes, food trials typically take about 12 weeks, and your pet cannot have even one off-plan treat, flavored medication, or table scrap during those 12 weeks.

Option B

Everyday Protein Rotation (After or Outside a Trial)

Both The Honest Kitchen and Stella & Chewy's support rotating between different proteins (chicken, beef, lamb, fish) within a line to keep mealtime exciting—just pause rotation during a strict food trial!

Single-Ingredient Treats & When to See Your Vet:

Single-Ingredient Treats

Freeze-dried single-protein treats (vital organs/meat from the exact same animal as your meal!)

Watch Flavored Chews

Check dental chews, pill pockets, and peanut butter jars so hidden poultry doesn't sneak in

No 'Hypoallergenic' Claims

We never call an OTC food 'hypoallergenic' or promise it cures allergies—only your vet diagnoses allergies

When to See the Vet First

Open or spreading sores, ear infections, vomiting, blood in stool, or not eating go straight to your vet

Important Vet Note: Hill's points out that environmental allergies (fleas, dust mites, pollen) are more common than food allergies. If your pet has open or spreading skin sores, severe ear redness, vomiting, diarrhea with blood, or is on a veterinary prescription hydrolysed/allergy diet, always consult your veterinarian first!

4. Four Keys from Our Pet Nutrition Team

AAFCO & Maker-Label Standards
01

Match Treats to the Main Meal

During a single-protein trial, use the kibble itself as training rewards or pick a 100% single-ingredient freeze-dried treat of the exact same animal.

02

Transition Gradually

Even when switching to a gentler limited-ingredient recipe, follow the transition directions on the new bag so the gut microbiome adjusts smoothly.

03

Keep a Simple Food Log

Write down the exact brand, protein, and date you started on the back of this sheet so you know which proteins your pet has already tried.

04

Ask Us to Check Your History

Before picking a novel protein, ask at the register—we'll pull up your past purchases so you pick a protein that is genuinely new for your pet!

How We Help With Pet Nutrition at All 6 Oregon Stores

  • We Flip the Bag Over Together (AAFCO Rules & the Maker's Own Label): At Wilsonville Pet Supply, Critter Cabana (Newberg), Gresham Pet Supply, Tigard Pet Supply, Salem Pet Supply, and South Salem Pet Supply, we never rely on front-of-bag marketing slogans or make medical promises. Bring a photo of your current food bag and we'll compare the Guaranteed Analysis, the AAFCO nutritional adequacy statement, and the first five ingredients side by side.
  • Frequent Buyer Program at Every Register: Just give your phone number at checkout at any of our 6 stores—buy 10 to 12 bags of most dog and cat food brands (Fromm, NutriSource, PureVita, Acana, Orijen, Nulo, Farmina N&D, FirstMate, Zignature, Open Farm, Stella & Chewy's, Primal, Northwest Naturals, and more) and your next bag of the same size is free! Because we track it by phone number in our POS, we can also look up the exact recipe your pet bought last time.
  • Zero-Deposit Special Requests & Vet Referral Standard: Don't see the exact bag size or formula your pet eats on our shelf today? Ask at the counter and we'll log a special request in our Command Center with zero deposit. Remember: we carry over-the-counter and vet-formulated diets (not prescription diets), so always see your veterinarian first if your pet has signs of illness (vomiting, blood, not eating, or a cat straining in the litter box), a diagnosed medical condition, or takes medications.

Common Questions (FAQ)

How can I get help with Limited-Ingredient & Novel-Protein Diets at your stores in Oregon?

Stop by any of our 6 family-owned Oregon stores—Wilsonville Pet Supply, Critter Cabana (Newberg), Gresham Pet Supply, Tigard Pet Supply, Salem Pet Supply, or South Salem Pet Supply. Bring a photo of your pet's current food bag and our team will gladly walk the aisle with you and compare labels.

How does your Frequent Buyer Program work on dog and cat food?

Just give your phone number at the register at any of our 6 locations—there are no paper punch cards to keep track of. On most major kibble, raw, freeze-dried, and gently cooked brands, when you buy 10 to 12 bags of the same size, your next bag is free!

Do you sell veterinary prescription diets, or over-the-counter specialty diets?

We do not sell veterinary prescription diets (if your veterinarian has prescribed a therapeutic Rx diet for a diagnosed medical condition, follow your vet's instructions). We stock a deep selection of over-the-counter vet-formulated, limited-ingredient, novel-protein, wholesome-grain, grain-free, wet, freeze-dried, and frozen raw diets.

What if my dog or cat is a picky eater or has a sensitive stomach when switching foods?

Always follow the gradual transition schedule printed on the back of your new food bag—mixing a small amount of the new food into the old food over 7 to 10+ days—and never starve a cat to force a food switch. Ask our crew about single-ingredient toppers, bone broths, plain canned pumpkin, or fermented goat's milk to support a smooth transition.
