UNDERSTAND THE ROOT CAUSE

Why your dog’s itching, paw licking, and skin flare-ups may actually start in the gut.

Dog allergies often start in the gut

Dogs, like humans, can develop chronic allergies. They don’t just come from food or surface irritants — the real cause often starts in the gut.


When the gut becomes imbalanced, the immune system can misfire. Instead of protecting the body, it overreacts, triggering inflammation, histamines, and ongoing irritation.


It starts from within

What weakens the gut and immune system?

Several common issues can disrupt your dog’s gut balance and weaken immune health over time:

  • Filler-heavy kibble
  • Poor nutrient absorption
  • Genetics
  • Environmental triggers

This internal imbalance can gradually affect digestion, skin, and immune function.
 

Built from the inside out

How gut imbalance shows up on the outside

When the immune system misfires, the effects often show up in visible and uncomfortable ways.

That’s when you start noticing:

  • Itchy skin
  • Paw licking
  • Ear infections
  • Hot spots

These symptoms often get worse with age if the root cause isn’t addressed.
 

Visible symptoms, deeper cause

Watch for these warning signs

If your dog is dealing with any of the signs below, the gut may be playing a bigger role than you think:

  • Persistent itching
  • Red or swollen paws
  • Excessive licking
  • Recurring skin or ear issues

Other signs may include hair loss, strange odors, and digestive troubles.
 

Know the signs early

A Growing Concern

Itching

10 million

1 in every 7 dogs suffers from constant itching each year.

Paw Licking

Target the Root Cause Behind Your Dog’s Itching & Allergies

Itchy skin, paw licking, ear issues, and hot spots may look like separate problems — but they often begin with the same internal imbalance.

The Shared Root Cause

Dogs can develop chronic skin and allergy symptoms when the gut becomes imbalanced. Poor nutrition, filler-heavy kibble, weak digestion, genetics, and environmental triggers can all weaken the gut lining over time.


When the gut is under stress, the immune system may overreact — releasing histamines and inflammation that can show up as itching, scratching, licking, redness, and hot spots.

Targeting the Root Cause Head-On

Letili is a complete daily all-in-one supplement designed to support your dog from the inside out. Instead of only masking surface symptoms, it helps support gut balance, immune health, skin comfort, and overall wellness.


Its advanced Tri-Biotic™ blend combines prebiotics, probiotics, and postbiotics with carefully selected nutrients to help promote healthier digestion and a calmer immune response.

Nourish, Repair & Restore Balance

Letili works daily to help nourish the gut, support skin health, and restore balance where your dog needs it most.

  • Tri-Biotics™ help support a balanced gut microbiome.
  • Omega-3s, turmeric, and quercetin help support a healthy inflammatory response.
  • Collagen, hyaluronic acid, and bone broth help support skin, coat, and tissue health.
  • Ashwagandha and reishi help support immune balance and stress resilience.

Together, these ingredients help support healthier digestion, calmer skin, and long-term immune balance — so your dog can feel more comfortable every day.

THE CHOICE IS CLEAR

Alternative Chews

80% fillers and  20% active nutrition - That means your dog gets very little of what actually helps — and the rest is wasted. Fillers can also have side effects.

No nutrional benefit: Fillers don't deliver the nutrition needed for our dogs on a daily basis.

Expensive - As low as $1.38 / day

0% fillers and 99.8% active ingredients - NO fillers, NO GMO, NO artificial flavors or colors, NO sugar, NO grains, NO side effects.

How long does it take to work? 

Many pet parents notice improvements in energy, digestion, and itching in as little as 7–14 days.

You’ll start noticing major improvements in 4-6 weeks. But remember, every dog is unique—some may feel benefits even sooner!

We ask you give at least 6-8 weeks since it may take a little long depending on severity of the issues.

How much should I give my dog?

** Each bag contains 60 scoops

Serve on top or mix with dry or wet food.

Dog’s Weight | Servings / Day

  • 0-15 lbs | ½ Scoop
  • 15-30 lbs | 1 Scoop
  • 30-70 lbs | 2 Scoops
  • 71+ lbs | 3-4 Scoops

How long will a bag last?

Here is how long each bag will last:

 

X-Small Dog (0-10 lbs) - 4 months

Small Dog (10-30 lbs) - 2 months

Medium Dog (30-70 lbs) - 1 month

Large Dog (70+ lbs) - 20 days

 

This is an approximate amount. You may adjust dosage as needed based on severity of the condition and size of your dog

Where is DA-1™ Daily All-in-One made? Where does my order ship from? How long does shipping take?

All Letili products are made in California. Your order will ship from Los Angeles, California within 24 hours of placing your order. Orders placed before 12pm (PST) ship same day in most cases. All orders are delivered within 2-5 business days (depending on your location).

How many bags should I get?

We recommend starting with a 3-month supply. This gives you enough to see the full benefits, and our multi-bag options come with discounts to make it even more cost-effective.

Are there any side effects?

Our formula is made with 99.9% active, human-grade ingredients and zero fillers, making it safe for daily use. Most dogs experience only positive results like better digestion, less itching, and more energy. As with any new supplement, a small number of dogs may experience mild digestive changes as their system adjusts — this usually passes quickly. If your dog has known sensitivities or you're unsure, we always recommend checking with your vet!

Will my picky eater like it?

Yes! DA-1™ is made with beef bone broth and real beef liver powder and pumpkin for a natural, irresistible flavor. Even the pickiest pups lick their bowls clean — no force-feeding or hiding pills needed.

Can this replace other supplements?

Yes — that’s the beauty of DA-1™. It combines joint, skin, gut, allergy, and immune support into one simple scoop, saving you time, money, and clutter from juggling multiple products.

Is this vet-approved and science-backed?

100%. Our formula uses only science-supported, vet-recommended ingredients — like Glucosamine, Probiotics, Omega-3s, and Turmeric — all backed by clinical research for real, lasting results.

What if my dog is already healthy?

Perfect! DA-01™ helps maintain your dog’s health long-term, keeping their joints strong, skin healthy, and immune system resilient. Prevention is the best medicine.

Can I use this with my vet’s medications?

In most cases, yes. DA-1™ is made with natural, food-based ingredients designed to complement most treatments. However, if your dog is currently on medications, we recommend a quick chat with your vet for peace of mind.

Is this safe for all breeds and ages?

Yes! DA-1™ is formulated for dogs of all ages over 3 months, sizes, and breeds.

From energetic puppies to senior dogs, just follow the recommended serving size by weight for safe daily support.
