Does garlic juice have same effect as garlic powder/garlic?

My poor pup has a nasty case of fleas and even though there's medicine on her, it's going to take a few days to fid her of all the tiny blood suckers. I read that if you put a little garlic powder in the dog's food, it'll make the dog's blood less attractive to the fleas because of some reason I forget.

Anyway, I didn't have any garlic powder and was afraid to give her minced garlic or fresh garlic directly in the food, so I just put about a teaspoon of the juice of the minced garlic that I have in a jar in the fridge. Same effect?

As far as i know an important property found in garlic is Allicin, and this occurs once (fresh) garlic is finely chopped, minced or crushed. Fresh, as in straight off the bulb and opposed to pre-chopped, aged and processed garlic is most potent and contains a slew of health benefits - one of which is the reduction of blood sugar levels and the purification of blood, along with many other anti-viral properties.

So the quantities needed from freshly chopped garlic would be far less than that of oils, pastes, powders, capsules etc to experience the same results and potency.

Fresh garlic is very strong and may cause irritation to the throat and stomach, so small quantities intitially to gauge tolerance is advisable.
