Is it safe to put flea prevention on a puppy?
The short answer is, yes, there are several options of flea prevention products you can choose from for puppies as young as 4 weeks old.
Longer answer … it all depends on your unique situation, the age of your puppy and comfort level.
I use a topical flea prevention on my weimaraner puppy, although I wish he didn’t need any flea prevention.
I brought Remy home when he was 8 weeks old, and I gave him a dose of topical flea prevention when he was 10 weeks. We chose a product our vet decided was OK for a puppy of Remy’s age.
Flea prevention is one of those topics where every dog owner has to make up her own mind about what is best for her own puppy. What is best for MY puppy is not necessarily best for someone else’s puppy.
Which types of flea prevention products are safe for puppies?
Obviously we all want to limit the amount of chemicals we put on our own bodies and on our pets, but puppies are especially tricky because they are smaller, more sensitive and still developing.
Most flea prevention products do not require a prescription, but I recommend you discuss with your puppy’s vet what is the most appropriate and safe flea prevention option based on your puppy’s age, the time of year and the risk of fleas in your area.
Ideally your puppy won’t need any flea & tick prevention! But unfortunately, that’s not always the case.
Natural options for flea prevention on puppies
Before you put any potentially toxic chemicals on your puppy, I recommend you look into some natural options. They might be all you need.
Not only are these generally safer for your puppy but they’re usually less expensive too.
Natural anti-flea sprays & shampoos for puppies and dogs
Natural anti-flea sprays and shampoos can be used for preventing fleas in the first place, but you could also use them if your puppy already has fleas.
Some anti-flea sprays and shampoos are safe for puppies, but you’ll want to check the minimum age and weight recommendation on the specific product you choose. (Each product is different.)
1-800-PetMeds® carries the Natural Chemistry Natural Flea & Tick Spray, which can be used on puppies. According to PetMeds, the product kills fleas and ticks on contact for up to seven days. Just ask your vet before using it on puppies under 4 weeks old.
Another option is Natural Chemistry’s natural flea & tick shampoo. This product also kills fleas on contact. Plus, giving your puppy a gentle bath helps with flea control in general because (ideally anyway) most of the fleas will drown in the bath water.
A flea comb
A flea comb is the best option for getting rid of fleas on newborn pups under 4 weeks of age, according to PetMeds.
There are no risks or potential side effects with using a flea comb as you are simply using it to gently comb the fleas off of your puppy’s coat. See: How to use a flea comb.
It’s unlikely puppies this young will have fleas unless you foster a litter from a shelter or take in a stray mother dog who transfers fleas to her pups. If that’s the case, ask your vet about the best way to treat the mother dog for fleas if she is also in your care. Do any of you have any experience with this? I’d like to hear about what you did to manage the fleas.
You can also try using a flea comb on older puppies or adult dogs, especially if you already see fleas (or “signs” of them) on your pet. A flea comb can be used with other flea prevention products and you could use the comb every day.
Food grade diatomaceous earth
Diatomaceous earth is a substance made from crushed fossils of freshwater organisms and marine life, according to Dogs Naturally Magazine. It is deadly to insects yet harmless to animals. It apparently works by dehydrating the insect or parasite.
I bought some DE for my puppy to put on his bedding and in his food in the hope that it would work as a natural de-wormer and flea prevention.
I didn’t use it consistently enough to say whether it made a difference. After I saw one flea on my puppy, I panicked and bought a chemical, topical flea prevention product.
“Spot on” topical flea prevention products
There are some natural “spot on” flea prevention products you can look into in addition to the natural options I mentioned above.
Unfortunately, sometimes natural products don’t work, and to control fleas in your home you may need to consider using some spot-on products that do contain chemicals.
Here are some examples of topical flea-prevention products considered safe for puppies, according to 1-800-PetMeds®. You would want to check with your puppy’s vet to be sure because each product has its own minimum age + weight recommendation. All of these products are available through 1-800-PetMeds®.
Spot on topical flea-prevention products for puppies:
Chewable flea-prevention tablets for puppies:
- Trifexis: For pups 8 weeks+ (Prescription required)
- NexGard: For pups 8 weeks+ (Prescription required)
There are other examples. These are just a few!
I use chemical flea prevention products on my animals, including my puppy, because:
1. We can’t use natural topical flea prevention products at our house due to allergies.
2. We kept having flea infestations until I put ALL my pets on topical flea-prevention products.
3. My senior dog has a serious skin condition and I can’t risk him getting flea bites on top of that.
While it’s general “safe” to use spot-on flea prevention with puppies of the appropriate age, I believe there are potential long-term risks of putting chemicals on a dog’s body.
As with anything else, it’s all about weighing the pros and cons and making the best choices for your own family. Also keep in mind that just because a product is “natural” does not mean it won’t cause an allergic reaction or other health issues.
When chemical “spot on” treatments are your only option
Since I use flea prevention products that contain chemicals, I do what I can to try to keep the amount of chemicals to a minimum. Here are a couple of tricks that work for me personally, but keep in mind this is going against the product’s label for maximum effectiveness.
1. I treat them every 5 to 7 weeks instead of every 4. Especially in the winter. You may be able to skip flea prevention entirely in the winter, depending on where you live.
2. I order the dose below my pet’s weight. I don’t do this for my dog Ace, but I do this with my cats. They are both at least 9 pounds but I order the “small cat” dose of flea prevention for cats 6 to 9 pounds. It still works.
(The above is what I do personally, and not a recommendation from 1-800-PetMeds or veterinarians.)

If your pet is in need of urgent or emergency care, contact your pet’s vet immediately.
What do you do for flea prevention at your house? Do you have a puppy or kitten?
