H Sophia,
I’ve had to fight fleas on my foster dogs. This is what has worked for me — first I wash the dog with a shampoo or soap that has tea tree in it (Dr. Bronner’s is a soap with tea tree that is the right ph for a dog’s skin – any castile soap is). Toxed has recommended Dr. Bronner’s mint soap as well. When bathing you will want to wet the head first as I’ve read that the fleas will scury towards the ears for protection — starting with the head will block them. Make sure to get soap everywhere but ears and eyes (in between toes as an example). Rince off and towel or blow dry.
Once dry I apply food grade diatomaceous earth down to the skin by parting the fur and taking a pinch of the DE between my fingers and making sure it gets on the skin not just the fur. Then I rub it in the area. (DE looks and feels like white flour but it actually has sharp edges. Those edges are harmless to us and our dogs (unless too much is inhaled) but are deadly to insects. They damage the exoskeleton and cause the insect/flea to dehydrate causing death.) I apply the DE from the top of the head to the beginning of the tail and across the back. If the dogs fur is light colored you can see the flea dirt and apply where it is seen. I have found that it is not necessary to do the entire dog — just head and back (I’m guessing this is the area where they feed?). I don’t spare the DE when I appy it but you do want to make sure to keep dust clouds down as breathing it in is not great for the lungs. I rebath and reapply DE about once a week or evey other week. DE can be a bit drying but after the fleas are dead and no more is applied the coat will go back to normal.
I also have a bottle of premade essential oils that are flea deterants. I’ll spritz some of that on all the dogs as a preventative. Here’s a premade product (there are others available) http://healthypets.mercola.com/sites/healthypets/natural-flea-and-tick-control.aspx
In the environment you want to vacuum (including baseboards and furniture that can’t be laundered etc). You also want to wash any bedding.
A few fleas is really not that hard to get rid of but if you don’t address it an infestation can develop and that can be a royal pain to battle.. Hopefully you have caught it early enough that one or two baths and one or two DE applications is all it will take along with vacuuming and laundering. If you end up with an infestation there’s more you can do but for now this, in my experiene, is a good start.
Good luck!!!
