How to Choose a Zero Waste Pet Shampoo Bar

There are a few important factors to consider when shopping for a plastic-free pet shampoo bar:


Always check the ingredients list carefully. You’ll want to avoid harsh sulfates, parabens, artificial fragrances or dyes that can irritate your pet’s skin.

Look for plant-based cleansers like castile soap along with moisturizing oils and butters. Essential oils add natural fragrance and benefits without irritating sensitive skin. Superfood ingredients like oatmeal, aloe vera, calendula and green tea also gently cleanse and soothe skin.

Patch test any new products since even natural ingredients can cause reactions in some pets. Monitor them closely after bathing and discontinue use if any irritation occurs.


Scent preference depends partly on your own nose and your pet’s sensitivities. Some dogs dislike strongly perfumed shampoos while others enjoy the aromatherapy benefits of essential oils.

Lighter scents like citrus or herbal notes provide a subtle freshness. However, pets with allergies or sensitivities may do best with a fragrance-free shampoo bar.

Strong artificial fragrances and dyes can be irritating so check the ingredients carefully. The concentration of essential oils also impacts scent strength.

Formula and Texture

Look for a rich lathering formula that also rinses clean without leaving residue all over your pet’s coat. Thicker shampoo bars tend to last longer while thinner formulas lather more easily.

Consider the bar hardness too. Very soft bars wear down fast from wet fur rubbing against them. But bars that are too hard can be tricky to apply directly onto the coat.

Moisturizing ingredients like plant oils and butters help replenish dry, flaky skin. But overly creamy bars may leave fur feeling greasy.

Effectiveness and Gentleness

You want a shampoo bar that cleans thoroughly but is also gentle enough for regular use. Harsher surfactants strip away dirt and oil but can dry out skin. Gentler cleansers may require a bit more scrubbing and elbow grease to fully lather and penetrate the coat.

Pay attention to the pH of ingredients as the skin’s ideal range differs between humans and pets. Alkaline soaps with a high pH can disrupt your pet’s natural acidic pH balance leading to irritation.

Only opt for anti-bacterial ingredients if your pet has confirmed skin infections. Otherwise antibacterial claims may do more harm than good for your pet’s microbiome. Always patch test first.


Eco-friendly, natural ingredient shampoo bars do often come with a higher price tag than generic drugstore brands. But you’re paying for quality while also supporting sustainability.

Some smaller businesses also offer great value if you look beyond the major brands. And buying larger sized bars or multi-packs helps lower the per ounce cost. You can also make your own DIY shampoo bars for a fraction of the store price.

Consider the cost savings over time from not repeatedly buying plastic shampoo bottles that just end up in the trash or recycling bin. The environmental benefits make bars worth the occasional splurge.

Brand Reputation and Values

Look into the brand’s reputation, transparency about ingredients and manufacturing, stance on animal testing and other ethics beyond just producing a zero waste product.

Support women-owned, BIPOC-owned and local businesses when possible. And choose cruelty-free and vegan brands that align with your values.

Frequently Asked Questions About Zero Waste Pet Shampoo Bars

Still have some lingering questions about making the switch from bottles to bars for your furry friend? Here are answers to some commonly asked questions:

Q: Are shampoo bars as effective as liquid shampoo?

Quality pet shampoo bars clean your pet’s coat just as effectively as bottled shampoos. They produce a rich lather with just a little water and scrubbing. The bar format may take some getting used to but many pet owners find bars even outperform bottles once they get the technique down.

Just be sure to store your bar in a dry location to prolong its use. The humid shower environment can cause the bar to soften and break down faster. Using a soap dish allows drainage and airflow so the bar dries out between uses.

Q: How often should I bathe my pet with shampoo bars?

The ideal bathing frequency depends on your specific pet’s breed, environment, activity level, skin sensitivity and more. As a general guide, follow your vet’s recommendations for your pet’s age group and breed.

But use discretion – over-bathing with any shampoo can strip the skin and coat’s natural oils leading to dryness. For most pets, brushing can remove dirt and distribute oils between full washings.

Watch for signs of skin irritation like excessive licking or scratching and adjust your washing schedule appropriately. Use a gentler shampoo bar and bathe less often if needed.

Q: Can shampoo bars cause skin irritation in pets?

It’s possible, especially for pets with sensitivities or allergies. Even natural ingredients can provoke reactions in some animals. That’s why it’s smart to patch test any new shampoo on a small area first.

Monitor your pet closely during and after washing to notice signs like scratching, licking, redness or dry flaky patches. Discontinue use immediately if you observe any concerning irritation.

Comparison shop for a gentler shampoo bar formula. Fragrance-free and fewer ingredients may help for easily irritated skin. Consult your veterinarian for personalized guidance.

Q: How do I switch from liquid shampoo to bars?

To help your pet’s skin and coat transition smoothly, first start by using up your existing shampoo before completely switching formats.

Once your bottle supply runs low, begin alternating washes with the bar and your old bottled shampoo. Gradually increase bar usage while decreasing liquid. This helps adjust the skin’s microbiome over time.

When fully switching, allow 4-6 weeks for your pet’s body to adapt before evaluating any positive or negative effects of the bar. Their skin and coat need time to rebalance. Monitor closely during this transition period.

The bar feeling and lathering process may take some getting used to after liquid bottles. But with a little practice, your pet’s skin should adapt well to the routine change.

Q: Can I make my own DIY shampoo bars?

You certainly can create your own homemade pet shampoo bars! The basic steps involve:

  • Choosing quality ingredients safe for animals like castile soap, carrier oils, essential oils, herbals extracts and more.
  • Using the proper ratios of hard oils, liquid oils and lye solution. Follow all necessary safety precautions when using lye.
  • Mixing and heating the ingredients to fully incorporate them before pouring the batter into silicone molds.
  • Allowing the bars to saponify for 24-48 hours then removing from molds and curing for 4-6 weeks until hard. Proper drying time is essential for hardness.

There are tons of detailed recipes and tutorials online for creating your own custom shampoo bars. But be sure to thoroughly research ingredient suitability, measurements and safety protocol before attempting.
