Any puppy flea treatment needs to be done carefully.
Chihuahua puppies should be 8 weeks old when they leave their mommas and go to their new homes.
If this is the case for your Chihuahua puppy, then fleas will not be a huge deal.
Puppies as young as 8 weeks can be treated with certain topical flea ointments, such as Frontline Plus.
However, if you have obtained your Chihuahua puppy younger than 8 weeks of age, then special considerations in your puppy's flea treatment needs to be addressed.
Hopefully, the momma will have been
treated with a flea preventative
during the time that she was nursing, as her protection carries over to her puppies and fleas will not be a major issue with your pup.
If you do have a puppy that is younger than 8 weeks and she does have fleas, do not bathe her with any type of flea shampoo.
It is dangerous to use any type of flea shampoo on a puppy that is younger than 12 weeks of age.
In this case, one of the best ways to protect your puppy is to make sure your house does not have fleas in it, or at least minimize that as much as possible.
Using a flea comb on your puppy, will be the best flea treatment option you have until she gets a bit older.
Though flea combs only target the adult, that combined with vacuuming will help to reduce their population until she is old enough to be treated safely.
Flea control for puppies should not include using a flea collar, even if it claims to be safe on puppies.
If your puppy is severely infested with fleas, a better option would be to take her to the vet and see if he can help.
If she only has a few, just vacuum and comb her daily until she reaches 8 weeks of age, then quickly get her on a topical flea ointment.
