Personally, I don't think I would use cedar oil, it's an intense one.. This is possibly a biased answer though- I have a pair of small animals, and anything I've ever read regarding small animals recommends avoiding cedar/pine oil like the plague, as it can really, really aggravate the sinuses/lungs, etc. I've also read that, evidently some essential oils can be pretty detrimental to a cat's liver.. ? However, I can't seem to find any info in relation to dogs.. Any info on Neem Oil, however, seems to be positive(medicinal for all types of species, not just human)
I did recently use a topical mix of organic oils for my dog, and this is what ingredients were listed:
Infused Neem(quick wiki:
Neem oil - Wikipedia, the free encyclopedia), Catnip, and Lemongrass, Organic Essential Oils - Clove, Cedarwood(oh, look at that.), Lavender, Tea Tree, Juniper Berry, Lemongrass, Eucalyptus, Citronella, Calendula.
The woman at the store(who is knowledgeable, and I believe owns the store- which is holistic, carries no live animals, and at that, no bunk products, and has some nice big fridges for raw..) expressed that the Neem and Calendula would be the most active ingredients in that mix.
I also found these handy things:
* ANTI-FLEA DOG BISCUITS
Makes about 5 dozen bone biscuits.
1 C. self rising flour
1/4 C. wheat germ
1/4 C. brewer's yeast
1 t. salt
1 T. plus 1 1/2 t. canola oil
1 clove garlic, chopped
1/2 C. chicken stock, plus 3 T. for basting (you can use beef or fish broth instead of chicken)
Heat oven to 400 degrees, spray cookie sheet with cooking spray.
Mix flour, wheat germ, brewer's yeast, and salt together in bowl. In a small bowl, mix garlic and oil.
Alternately add 1/2 C. chicken stock and oil/garlic mixture to flour mixture, mix until well combined.
Knead about 2 minutes by hand on a floured surface, dough will be sticky.
On a lightly floured surface, roll dough out about 3/8 inch thick. Cut out bone shapes (or just cut into squares).
Bake 10 minutes, rotate baking sheet and baste with remaining 3 T. stock.
Bake 10 minutes longer.
And:
You can also concoct your own homemade flea spray! In a 16 oz. spray bottle, mix the following: 2 tablespoons cider vinegar; 1 cup Avon's Skin-so-Soft; 1 cup water; 1/8 teaspoon oil of citronella (optional - don't use if your pet hates the smell). Rub into your pet's coat to repel fleas and mosquitoes.
