What to Look for?

Dog Fluffy elaborates that there are a few things you should look for, before choosing a commercial flea treatment.


Picking a puppy flea shampoo with natural ingredients is vital because dogs aren’t used to having chemicals on or in their body. Newborn puppies have sensitive skin, and require the safe ingredients to maintain healthy skin and fur.

Natural ingredients, such as oats, aloe, and coconut oil, should always be used.

Tearless Shampoo

Nicole Cosgrove explains that many products promise to be “tear-free,” which indicates the formula will not irritate the eyes if it comes into contact with them.

Because puppies are squirmy, they are much more prone to get shampoo in their eyes or lips, therefore a completely tear-free shampoo is essential. Not all formulae work the same way, however products containing natural elements are usually tear-free.


Scented shampoos have pros and cons. If it is aromatic due to natural components, it is pretty much safe. Be careful if the word “fragrance” appears in the ingredient list. This is an actual pick up term which refers to harmful substances without explicitly listing them.

Scented shampoos can simply add a scent to your dog’s coat without neutralizing or deodorizing it, undermining the point of having a scent in the first place. Still, scented shampoos can indeed be beneficial if they remove odors and add a light scent.

Fragrance-free shampoos are the safest alternative because they are unlikely to carry the word “fragrance” on their ingredient list. Make sure that they at least neutralize scents, because if not, your puppies will be clean but still stink.

Obscure Chemicals & Brands

There are a few substances you don’t want in your dog’s flea shampoo. This includes any harmful chemicals. You should speak with your veterinarian to see what they suggest.

Shampoos that do not Heal

Keep in mind that not all shampoos will destroy both flea eggs and adult fleas. If the flea shampoo you’re using isn’t effective on both, you might try a spot-on treatment. The spot-on therapy will help make sure that the flea’s life cycle is properly interrupted.

Similarly, using flea collars on pets helps keep these insects away.

How Can I Tell if my Puppy is Infested with Fleas?

There are various methods to identify whether your puppy has fleas, according to Pet Reviews. If your pup is scratching frequently, he may have fleas.

While scratching is common in dogs, it can be a sign that he has fleas, especially if he begins to bite the spot where he is scratching.

You can thoroughly check its skin and hair to see whether he has fleas. It’s something you need to do at least once a week. Fleas are around 0.1 inch long and hide in your dog’s fur. Fleas are most commonly seen in the groin and armpit areas.

You may also observe flea feces on your dog, which is black when dry and red when moist. When you brush your dog with a white towel, you can see the flea feces drop onto the towel.

When a dog is bitten by fleas, it commonly causes an allergic reaction. If your puppy has short hair, the flea bites on his body should be visible. Fleas may also be found around your dog’s typical hangouts, like his food bowl and sleeping space.
