    I have been using this supplement on my dog once daily since she was a baby. She just turned 8. I cannot express in words how much I love and swear by this supplement. I recommend it to every single person I can. As a dog groomer my dog has attended a kennel setting every week of her life and she has never once been sick or picked up any of the common illnesses going around and I never worry that she will. Any little cut or scrape or thing that happens to her heals so much faster then I would anticipate on your average dog. My dog just turned 8 years old and she has not slowed down at all, and I am constantly told that she looks 2 years old still. I will give this supplement to every dog I ever have for as long as they continue to produce it, and I sure hope they never discontinue it because it is gold in liquid form. I can testify after being an 8 year user of this product that supporting your pups immune system will be the best decision you could ever make for them. I cannot say enough about the results and confidence I have in this product. If I could give it 100 stars I would.

    Even though this product isn’t specific to this use, I used it to clear up a gut imbalance in my rat terrier who was always having tummy issues and bad gas. I didn’t want to put her on an antibiotic and so when I read the back of this product and realized it included several strong anti microbial herbs I decided to give it to her in combination with cultured goat cream for probiotics. A lot of the formulas made for stomach issues center around soothing the tummy but not killing off unwanted bacteria and yeast. And this formula contained antibacterial herbs and antifungal herbs. Another issue with tummy specific formulas is they tend to have probiotics, which can feed bad bacteria and yeast. Yes they can help feed good probiotics but they aren’t a good thing if your dog had an existing tummy bug. That’s why I used the cultured goat cream instead. Combined with this formula her has went away and she stopped having episodes of turning down food and eating Grass in the morning. \r\n\r\n It’s really resolved her regularly tummy issues

How long have these formulas been around?

Our Apothecary formulas have over 30 years of heritage.

Earth Animal was founded in 1979 by Dr. Bob and Susan Goldstein. Dr. Bob, an integrative veterinarian, began developing herbal formulas in his practice decades ago. Long before "holistic/integrative pet care" was mainstream.

The Apothecary story:

  • Our Supplement Formulas developed through decades of clinical veterinary practice
  • Crafted by a master herbalist in the Green Mountains of Vermont
  • Refined over 30+ years based on real-world results
  • Rooted in traditional herbalism, backed by modern understanding

These aren't new-to-market formulas chasing trends. They're time-tested blends that have helped countless dogs and cats over three decades. That's why we say we're "Rooted in Nature, Backed by Science".

How long does it take for supplements to work?

They don’t work overnight, and that’s the point. Our supplements are designed to support the body over time What to Expect

  • You may notice small changes within a few days
  • Most benefits build over 2–4 weeks of daily use
  • Continued use helps maintain balance long-term

Why It Takes Time: We’re not forcing a quick fix. We’re helping your dog or cat build from the inside out, supporting digestion, skin, immune function, and overall wellbeing in a way that lasts. For Best Results

  • Use daily, consistency is everything
  • Stick with it, don’t skip around
  • Give it time to do what it’s designed to do

A Simple Way to Think About It: You’re not flipping a switch, you’re building a foundation.

Stay consistent. Give it time. That’s when you’ll see the difference.

Can I give supplements to my pet if they're on medication?

If your dog or cat is on medication, it’s always best to talk with your veterinarian before adding anything new. Herbs and supplements can be incredibly supportive, but they can also interact with certain medications, depending on what your animal is taking. A Simple Approach

  • Start with a conversation with your veterinarian
  • Share the product or ingredients you’re considering
  • Take it slow and introduce one thing at a time

Why It Matters We believe in supporting the body naturally, but it has to be done thoughtfully and safely, especially when medications are involved.

When should I use Immune Support?

The immune system isn’t something you wait on, it’s something you support every day, especially when life puts pressure on it. Immune Support is designed for both proactive care and moments when your dog or cat needs extra resilience. When to use it proactively:

  • Seasonal shifts (cold, damp, or high-exposure times)
  • During stress (travel, boarding, new environments)
  • For senior pets or those needing extra support

Because stress, change, and environment can all challenge the immune system. When your dog or cat may benefit from extra support:

  • Low energy or just “not themselves”
  • Occasional sniffles or seasonal challenges
  • Skin or coat that feels out of balance
  • Times of recovery or increased demand on the body

Why it works: A blend of traditional herbs chosen to help the body stay strong, balanced, and responsive: Astragalus & Echinacea – help support a healthy, active immune response Elderberry – rich in antioxidants to help defend against everyday challenges Turmeric – supports a balanced inflammatory response Ashwagandha – helps the body adapt to stress, a key factor in immune health Together, they support the body’s ability to respond, recover, and stay in balance.

Because this is a potent blend, check with your veterinarian if your pet is pregnant, has underlying conditions, or is taking medications.

How do I give the liquid herbal drops to my dog or cat?

Simple. Easy to work into your routine. Ways to Give

  • Directly in the mouth using the dropper (count the drops first so you know your dose, start small and build from there)
  • Add to the water-if you choose this route switch water daily and add new drops
  • Mix into food

Whatever works best for your dog or cat

Start Slow

  • Begin with a smaller amount
  • Build up to the full dose over a few days
  • Let it become part of the routine

Dosing by Weight

  • 3–7 lbs: 4 drops
  • 8–15 lbs: 5–8 drops
  • 16–35 lbs: 10–12 drops
  • 36–85 lbs: 15–18 drops
  • 86+ lbs: 20–25 drops

How Often

  • Short-term support: twice daily
  • Ongoing support: once daily

For Picky Dogs and Cats

  • Mix into wet food or a favorite topper
  • Add a splash of bone broth
  • Start small, they’ll get used to it

Why Consistency Matters This is where the real benefit happens. With regular use, the herbs work to support balance in the body over time, helping your dog or cat feel more comfortable, resilient, and supported day after day.

The longer you stay on it, the more you’ll notice the difference.

Storage Keep in a cool, dry place. No refrigeration needed. The Takeaway Easy to give. Built over time. Real support you can see. Stay on it — and watch what changes.

Why do the liquid herbal drops contain alcohol?

Our Herbal Drops are traditional tinctures, crafted to draw out the full intelligence of each herb — not just a portion of it.

Why we use alcohol and glycerin together:

To extract what matters most. Alcohol is one of the most effective ways to pull a full spectrum of beneficial plant compounds, including those water alone can't reach. Vegetable glycerin is added to help carry those compounds and to make the formula more palatable.

To preserve naturally. The alcohol and glycerin combination protects the integrity of the formula without synthetic preservatives. What goes in stays stable, clean, and true over time.

To deliver efficiently. Tinctures are highly absorbable. They're designed to be recognized and utilized by the body, quickly and effectively.

What about safety? The amount of alcohol used per serving is very small — just a few drops, typically mixed into food or water. At recommended use, it's well within safe levels for dogs and cats.

If you'd like to minimize it further

  • Add drops to warm (not hot) water and let sit briefly
  • Mix into food rather than giving directly

Some of the alcohol will naturally dissipate.

Why this approach? Many alcohol-free formulas rely on synthetic preservatives or sacrifice potency. Our tinctures use alcohol and vegetable glycerin together — a traditional combination that lets us carry forward everything the plants offer, not just what's easy to extract.

Our Standards Our Impact

Forty-five years of refusing to settle.

Two founders. One conviction. A refusal to accept what this industry calls good enough. Dr. Bob Goldstein on the science. Susan Goldstein on the conscience.

Over decades of holistic veterinary practice, Dr. Bob saw the same thing again and again: animals responding to plant-based support in ways that conventional medicine had overlooked. That experience became the foundation for Apothecary: a range of herbal drops formulated with clinical intent, built around the eight most common wellness needs, and designed to work gently with your pet's biology rather than override it. Time-honored botanicals, held to a modern veterinary standard. 

Family owned since 1979, still guided by the same belief that started it all: that the animals we love deserve far better than they're usually offered.
