New puppy has fleas! What's the fastest way to get rid of them?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 2 months and 7 days old | 45 lbs

Hello, my family and i very recently adopted our puppy. Tonight i noticed what appeared to be a flea on the floor. It was black thin & jumped around. He is due to get the frontline on 1/27/18. Per North Shore’s vet, preventative care is to be done monthly. Chase is not scratching or biting excessively but he occasionally does. If he does have fleas we want to put an end to it ASAP before it gets worse. Would like to know what we should do and how can we get rid of the fleas if he does have more.

Congrats on your new puppy! They can be such a lovely addition to the family, but I'm sorry that Chase may have fleas. There are a couple of things you can do now for him. First I would give him Capstar. It's a one time pill that starts killing fleas in 30 minutes, and it's safe to give daily until it's time for his Frontline treatment. I'm not sure if he's already had a Frontline treatment previously, but if he hasn't not, it's fine to give him the Frontline treatment now. He's old enough for it, and it's close enough to the due date. You will also have to disinfect the environment. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. Good luck with him, I hope this helps!

I found 2 fleas on my 5 month puppy. What should I do?
Great question! I will give you a flea treatment program for Lioh. First, I would give him Capstar. It's a one time pill that starts killing fleas within 30 minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home.

Treated my adult dog for fleas last week got new puppy today and realised he has fleas just treated him now but just wondering could my adult dog still get the fleece even do he was only treated last week
Great question! Your adult dog should be protected, but the house will be infested and he can get the fleas when the flea treatment wears off. I can give you a flea treatment for Brody, since he is almost 8 weeks of age. First, I would give him Capstar. It's a one time pill that starts killing fleas within 30. minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. I hope this helps!

Here is a way to get rid of fleas: Unfortunately fleas only hop on the body of your pet when they want to feed, then they hop off again and stay in your pet's environment. So you need to treat all pets in the household as well as the environment (which contains the fleas, their eggs and larvae). Flea treatment:  1) Get some flea medication such as a Flea spray or a spot on from a pet shop or your veterinarian and apply monthly 2) get flea powder, put some in your vacuum cleaner bag and vacuum your house and furniture and also non-carpeted areas frequently to remove flea larvae and eggs which live off house dust., Dispose of the bag in the trash outside. Hot-wash all the pet's bedding, If you do this diligently for a few months you will get rid of the fleas. Flea products: Spot-ons and/or chews Advantage, Advantix Advantage Multi (Advocate in the UK) Frontline (ticks as well) Bravecto spot on (ticks as well) - for cats, in tablet form for dogs Simparica, Nexgard Revolution (stronghold i

My dog has fleas. He’s itching really bad but he doesn’t see the doctor until Monday. Is there anything I can give him to help subside the itching? He is a bullmastiff that weighs roughly 140 lbs.
Poor Tyson! I can give you a flea treatment program for him. First, I would give him Capstar. It's a one time pill that starts killing fleas within 30 minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. You can also try giving him an oatmeal bath or a bath with a flea shampoo you get from the pet store to give him temporary relief. Best of luck.

Hello! I recently got my dog, her name is Blacky. We got her from the neighborhood. I just wanted to know what is the best recommended, flee and tick shampoo that I should use?*
Flea and tick shampoos do not provide lasting protection. I will give you the flea treatment program that has always worked for me. First, I would give Blacky Capstar. It's a one time pill that starts killing fleas within 30 minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash her bedding in hot soapy water, and vacuum the furniture and carpet surfaces.

Hi! Lupito is just 2 months old and he has never been outside the house because he is not yet vaccinated. I noticed that some parts of his back does not have hair, he is loosing a hair and he is scratching too. What can it be?
It could be fleas. Fleas can be brought in on your clothes or by other animals in the house. First, I would give him Capstar. It's a one time pill that starts killing fleas within 30 minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces.

Ive got a rescue puppy who hasnt had her shots yet and may definitely has fleas. Hasnt been vaccinated i need to know what steps to take next.
Congratulations on your new puppy! I would recommend taking her to a vet's office to get her shots as soon as you can, since she's at risk for contracting diseases like parvo or distemper right now if she's never been vaccinated. Your veterinarian can also get her started on a good quality flea medication. She will probably also need a fecal test and deworming to get rid of any parasites, which are very common in puppies. If you want to give her something for the fleas before you're able to get to the vet, K9 Advantix is the most effective over-the-counter option for fleas.
