The Balancing Biome Pet Shampoo Bar by The Animal Bar is a vet-formulated, hypoallergenic, soap-free, and fragrance-free solid shampoo for dogs and cats, specially crafted for pets with sensitive, dry, or allergy-prone skin. Unlike many other pet shampoo bars on the market that contain soap—which can disrupt the skin's natural pH and cause dryness or irritation—this bar is completely soap-free and pH-balanced to gently cleanse without stripping your pet's natural oils. It features a plant-based formula with moisturizing shea and mango butters, along with calming organic botanicals like chamomile, calendula, nettle, horsetail, St. John's Wort, and licorice root to support a healthy skin barrier. It lathers easily, rinses quickly, and is simple to hold and use, making bath time stress-free for you and your pet. One concentrated 3 oz bar lasts as long as two 8 oz bottles of liquid shampoo, offering a long-lasting, low-waste alternative. Vegan, cruelty-free, and packaged without plastic, it's also free from artificial fragrances, sulfates, parabens, silicones, and colorants—making it the ideal sustainable and gentle shampoo choice for conscientious pet parents who want only the best for their dogs and cats.
