Yes, Capstar (nitenpyram) is labeled as being safe for use in pregnant and lactating dogs. Just remember that Capstar will quickly kill adult fleas, but will not provide lasting flea prevention against hatching flea eggs or maturing flea larvae. K9 Advantix II is also labeled as being safe for pregnant and lactating dogs and will provide month-long flea prevention, but you would need to closely monitor the puppies to keep them away from the areas of medicine application. I hope this helps and that all goes well!

    Great question! Many flea collars are not safe to use on nursing dogs, and it doesn't say on the package insert this can be used on a nursing dog. I would therefore not use it. Instead, I would put Revolution on her. This is a spot on treatment that is labeled as safe for use on nursing dogs. I hope this helps!

    Hi there. I don't typically recommend flea collars for lactating (nursing) females. Oral medications like capstar are considered safe for lactating mothers and are relatively inexpensive. Other medications are available through your vet that are safe for nursing mothers. Please don't purchase other over the counter medications for your female-some of them can be quite dangerous. I hope this helps!

Eris has 2 week old puppies. She also has fleas, can I put a flea collar on her yet? And do those $5 ones work?

My 3 yr old Pit Bull just gave birth to 8 puppies. She had fleas but by the time we noticed...She gave birth and pups have them too! What can we do?
Revolution (a spot on treatment) and Capstar (a one time pill) are both approved for use in lactating dogs. I'd give Bella Capstar, which will start killing the fleas in 30 minutes, and then following up with Revolution. You cannot use any flea treatment on the puppies unfortunately, they are still too young. The only solution is to try to remove the fleas manually. Gently bathe the puppies in warm water, using your hand to support their heads and keeping them above water. Don't use any products, just warm water (at the same temperature you'd bathe a baby), and scoop water over their backs until wet. Then gently dry them with a soft towel. Use a flea comb to groom the puppies coats and remove fleas. Flea combs have teeth that are very close together and work by physically pulling fleas out of the fur. Start at the puppy's neck and part the fur, combing a section at a time until you have covered his whole body and removed all of the fleas. It's important to kill any fleas that you remov

My dog is pregnant with bad fleas. She is due in a few weeks. Can I use permitherin cream 5% to treat her fleas!!!!
No, this is not safe to use on your dog. Revolution is a spot on flea treatment, and it is approved and safe for use in pregnant dogs. You can get this from your vet's office. I'd recommend using Capstar as well. It's a one time pill that starts killing fleas in 30 minutes and is also safe to give pregnant dogs. Give her the Capstar to kill the fleas, and follow up with the Revolution. You will have to disinfect the environment as well. Wash her 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. Just keep her out of any room where you use Indorex or a flea bomb until the room is completely dried. I hope this helps!

Hi, thanks for using Boop by Petco! Frontline Plus is labeled for use in pregnant dogs. K9 Advantix is NOT labeled for use in pregnant dogs and using it is considered off label use. I hope this helps and good luck!

I have two female dogs who are pregnant and that have fleas. My cat has a tapeworm as well. I wanted to know if topical flea treatments are safe for pregnant bitches and are there any tapeworm preventatives that are safe for them as well.
Frontline and Revolution are safe for use in pregnant dogs. If you're already using a heartworm preventative with ivermectin, please continue to do so as it is safe for both the mom and pups and will help prevent her from passing parasites to the pups. And if they is due for vaccinations, getting them while she is pregnant will boost her and the pups immunity to disease. For tapeworms, Drontal is safe to use during all life stages, including pregnancy.

Is is really safe to use frontline to my pregnant shih tzu
Yes, Frontline is considered to be safe for use in pregnant female dogs. The active ingredient (fipronil) has never been shown to cause any birth defects or other problems, and it's poorly absorbed into the body in any case so should not affect the developing pups at all :)

Hi, I have a Siberian Husky who is 6 weeks pregnant and I have noticed she still has fleas after given her a treatment back on 4/10 (without knowing she was pregnant). I gave her one treatment of the PetLock Max for dogs. I think this medicine didn’t
She can get her rabies shot now or you can wait until after she had her puppies. As for 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: Advantage, Advantix Advantage Multi (Advocate in the UK) Frontline (ticks as well) Bravecto spot on (ticks as well) - for cats, in tablet form fo

I am giving my cocker Nexguard to prevent fleas, and am wondering if that is enough protection, or should I use a topical also? We do not have an infestation, just saw one occasionally. Never saw eggs, larvae,flea dirt. Treated house as preventative,
You do not have do use anything else if you use Nexguard, if you start finding fleas just switch to a different type of flea treatment such as Bravecto or Advantage. When pregnant the only safe product is Frontline.

Hello . Washing the pregnant dog with a anti flea shampoos is safe for her children ? What about eating chewable tablet or vaccination?
Hi, thanks for using Boop by Petco! It depends on the active ingredient in the shampoo, but likely no. Pyrethrins are not safe in pregnant dogs. I would contact your Vet for Fipronil products or look online. I am assuming by "children" you mean the puppies and not human children. If you want to tell me the name of the shampoo and the chewable tablet I can look in to it's safety. I do not recommend vaccinating pregnant dogs. I hope this helps!
