Here's a client handout written in plain language, ready for you to copy into your clinic's template:

Why we're doing this

We think your pet's itching, ear infections, or tummy troubles might be caused by a food allergy. The only reliable way to find out is a food trial — feeding a special diet and nothing else for 8 weeks straight to see if the symptoms go away.

Blood tests and saliva tests for food allergies don't work well, even though you may have heard about them. The food trial is the gold standard.

How it works

For the next 8 weeks, your pet eats only the diet we prescribed today — and that's it. No exceptions. If their symptoms clear up, we'll know food was the culprit. If they don't, we've ruled food out and can look at other causes.

What your pet CAN have

• The prescription diet we sent home
• Plain water
• Any medications we've specifically approved

What your pet CANNOT have — even a tiny bit

• No other food. Not even a different bag of "the same" diet.
• No treats. Not store-bought, not homemade, not "just one."
• No table scraps or human food. Not a crumb off the floor.
• No flavored chews or dental treats. Including pill pockets.
• No flavored medications or supplements. Including chewable heartworm or flea/tick preventatives — please ask us about non-flavored alternatives.
• No rawhides, bully sticks, or chew toys with flavor.
• No food from other pets' bowls. Feed pets separately if needed.
• No licking dishes, the floor, kids' faces after meals, or anywhere food has been.

One slip resets the clock. We mean it. Even a single hot dog or a stolen bite of cheese can ruin 6 weeks of progress.

Tips to make it work

• Tell everyone in the house — especially kids and visiting grandparents.
• Put a sign on the fridge if you need to.
• Walk on a short leash so your pet can't scavenge outside.
• Separate pets at meal times if you have more than one.
• Switch to an unflavored or "treat" version of preventatives — call us, we'll sort it out.
• Use the prescribed kibble as treats. Pull out a handful from the daily portion, give it as rewards throughout the day. It still counts as one meal.

What to watch for

Keep a simple log — even a note on your phone is fine. Each week, jot down:

• Itching level (0 = none, 10 = constant)
• Any ear scratching or head shaking
• Stool quality
• Any vomiting or diarrhea
• New or improved skin spots

Bring this with you to your recheck.

When to call us

• Your pet won't eat the new food after a few days
• Symptoms get noticeably worse
• New problems pop up (vomiting, diarrhea, lethargy)
• You accidentally slip up and aren't sure what to do
• You have any questions — we'd rather hear from you than have you guess

Your recheck

We'll see you in 8 weeks to check progress. If your pet is much better, we'll talk about the next step: a "challenge" — reintroducing the old food briefly to confirm the diagnosis. If symptoms haven't budged, we'll discuss what to investigate next.

You've got this

Eight weeks feels like a long time, but it's the most reliable way to find an answer. Stick with it — we're rooting for you both.
