I just got a 2 month old chihuahua and noticed fleas in its fur.  Gave it a bath and still I saw one.  Any suggestions?

he's still a baby!

don't use any chemical anti-flea medication just yet
instead, try using 3 tablespoons of apple cider vinegar mixed with a liter of water as a spray for your puppy's skin
spray until it soaks the skin

fleas hate the acid plus it's safe for your puppy
just don't let it go to his eyes

hope this helps

Old Fashion but try -- Unscented Talcum Powder --it can't hurt.

 

Can ordinary vinegar do? because i can't find apple cider vinegar mixed. I tried Talcum powder but it is not effective with respect to my pet.

There is another one I would like to add besides the vinegar. I would suggest oatmeal soap can do the trick.
