If you’re searching for a pet shampoo as the new year approaches, you may feel a bit lost in the aisle. Bottles with smiling dogs and glowing cats line the shelves, each one “gentle,” “moisturizing,” or “hypoallergenic.” We want the best for our furry family, but bold claims and bright colors don’t always mean safety. The truth is, some shampoos labeled for pets are hiding ingredients that might do more harm than good. Knowing what to look out for—and what to avoid—can keep your dog or cat clean, happy, and itch-free.
At Dogtown in Gloucester, MA, we see the effects a good (or bad) shampoo can have during grooming appointments every week. With the right knowledge, you’ll confidently choose products that protect your pet’s health, not just their shine.
Why ingredients matter more than ever
Pets can’t tell us their skin is burning or their fur feels dry. Cats and dogs simply endure, even as certain chemicals build up on their skin. As more research comes out in 2025, it’s clear that ingredients safe for humans aren’t always safe for animals. Some formulas still rely on artificial dyes, sulfates, or harsh alcohols, even though pet skin is delicate and more prone to reactions.
Skin irritation can start small—but fast. Red spots, itching, or even licking can signal something’s wrong.
This is one reason Dogtown always reviews product labels before using anything new for our clients. Whether for cat grooming or routine dog baths, safety always comes first. Here’s how you can do the same at home.
Ingredients to watch out for in 2025
The list of “bad” ingredients has grown as science learns more about what pets can tolerate. Some components are still common—a familiar fragrance, a cheap preservative, or a sudsy agent. But experts and pet care facilities like Dogtown recommend skipping any shampoo with the following:
- Sulfates (like Sodium Lauryl Sulfate): These are foaming agents. In people, they’re fairly common, but on pets, they can strip natural oils and cause dry, flaky skin or worse—itchy rashes.
- Parabens: Parabens are used to stop mold, but studies suggest they may affect hormone balance in both humans and animals.
- Artificial fragrances and dyes: Lab-made scents and synthetic colors can lead to sneezing, hives, or more subtle allergies. Pets with sensitive skin are especially at risk.
- Phthalates: These are often hidden in products labeled as “fragranced.” They’re now suspected of affecting fertility and overall health.
- Alcohols: Not all alcohols are bad, but short-chain alcohols like ethanol and isopropyl can dry out fur and skin. Look instead for “fatty alcohols” like cetyl or stearyl, which actually help lock in moisture.
- Formaldehyde-releasing preservatives: Look for ingredients like DMDM Hydantoin, Imidazolidinyl urea, or Diazolidinyl urea. These have been linked to allergic reactions and, potentially, even cancer.
- Coal tar dyes: Sometimes used for color, coal tar-related ingredients can trigger serious skin reactions and are not recommended for animals.
- Polyethylene glycols (PEGs): Used for texture and thickness, these may have some contamination risks. While rare, pets with sensitive skin could react badly.
It all sounds technical. But the bottom line is, if you notice anything on a label you struggle to pronounce—or see something on the list above—it might be better skipped. The fewer the ingredients, the better.
A closer look: why these ingredients can hurt
Imagine your dog coming home from a muddy trail, needing a good wash. You reach for the closest shampoo, not thinking twice about what’s inside. But the wrong ingredients can linger on their skin, sometimes causing problems for days after the bath.
Sulfates and dry skin
Sulfates clean well, but a little too well. They’re often in shampoos to create lots of bubbles, but they can scrub away those tiny—but important—natural skin oils. Dogs and cats don’t have as oily skin as us, so even one wash can upset their natural barrier.
Parabens and long-term effects
There’s a lot we don’t fully know about parabens yet, but the risk of hormone disruptions is enough to steer clear until research catches up. Puppies, kittens, and older pets may be even more at risk.
Artificial fragrances and allergic reactions
We all love the idea of a pet that smells like vanilla cupcakes. But most synthetic scents are just marketing—dogs, in particular, have a far stronger sense of smell and can be left feeling overwhelmed or itchy after a fragranced bath. Reactions can show up as minor as redness around the nose or more serious, like full-body hives.
Alcohol and irritation
It’s tempting to think alcohol will help clean extra-dirty fur, but harsh types can leave your pet more uncomfortable than before. Stick to milder formulas, especially for pets with fine coats or anyone prone to dry skin already.
If you wouldn’t put it on your own skin, why use it on your pet?
Reading labels (even if it feels intimidating)
It’s easy to feel a little overwhelmed by shampoo ingredient lists. They’re long, technical, and the font is sometimes tiny! But you can do it, even if chemistry was never your favorite class.
- Look for short ingredient lists.
- Avoid lots of additives with numbers or long chemical names.
- Check for natural oils (like oatmeal, sunflower oil, or aloe) listed as the main ingredients—not just at the bottom.
Pet care companies are slowly moving toward clearer, simpler ingredients, but it may take another year or two to become the norm. Right now, the responsibility still falls on pet parents to double-check.
If you ever need a hand, Dogtown’s experienced staff is always happy to talk about what they’ve found works for sensitive skin during day camp activities or boarding stays. Experience goes a long way in knowing which products to trust.
The value of “natural” and “organic”—and when to question it
You’ll see a lot of bottles boasting “all natural” or “organic” on the front label. While this can signal a better formula, it’s not a guarantee. Sadly, the pet industry sometimes uses these terms loosely. That’s why it’s so important to check the small print. If the so-called organic shampoo still lists dyes or perfumes, look elsewhere. Transparency matters, even in cute packaging.
Don’t forget: every pet is unique
I know—everyone wants a simple answer. But each dog and cat is different. What works beautifully for a low-shedding French bulldog may not suit the long, thick coat of a Maine coon. At Dogtown, we see shy kittens, playful seniors, and energetic puppies, and they each have grooming needs as unique as their personalities. Sometimes, even “safe” ingredients lead to a little itching or dryness. Watch how your pet reacts after a bath, and don’t be afraid to try something new if they seem uncomfortable.

Frequently asked questions
What ingredients should I avoid in shampoos?
Try to avoid sulfates, parabens, artificial fragrances, dyes, phthalates, harsh alcohols (like ethanol and isopropyl), formaldehyde-releasing preservatives, coal tar dyes, and polyethylene glycols (PEGs). These ingredients can dry out skin, trigger allergies, or raise health concerns for pets.
How to know if a pet shampoo is safe?
Start with the ingredient list. Choose short, simple lists focused on plant-based cleansers like oatmeal or aloe and free of harsh chemicals. Products labeled for pets, designed for their unique skin, and without unnecessary additives are usually safest. Ask experienced groomers, like those at Dogtown, if you’re uncertain.
What are the best pet shampoo brands?
Rather than focusing on brands, look for products with clear ingredients, minimal chemicals, and a focus on pets’ well-being. Choose shampoos reviewed or recommended by trustworthy grooming professionals, such as those used during Dogtown’s grooming appointments, and trusted veterinarians.
Where to buy safe pet shampoos?
You can find quality shampoos at local pet stores, through reputable pet grooming providers, or online. Always take a minute to read labels before buying. If you’re using professional grooming services, like Dogtown’s grooming team, you can ask about the products they use and trust.
Can human shampoo be used on pets?
No, it’s not recommended. Human shampoos have pH levels and ingredients more suited to human skin, which can upset a pet’s natural oils, dry them out, or cause irritation. Always stick to shampoos made specifically for pets, even if the “for humans” formula is gentle.
