My dog's weight is 50kg, can i use it? Will it be effective?

No. This is specialized for dog weighing between 20-40kg only. You can use the spot on available for 40-60kg body weight for great results.

I want to know with shampoo when can I bathe my dog after application?

Doctor normally suggest to give a gap of 1 week so that skin absorbs it fully. I maintain the same.

Is it in injection form & how should it be administered ?

It is in a simple & easy to squeeze pipette form. How to apply?  Break the snap-off top from the pipette along the scored line.  Part the hair at back of dog, at the base of the neck, until the skin is visible.  Place the tip of the pipette on the skin and squeeze gently at one or two spots to empty its contents onto the skin.  Care should be taken to avoid excessive wetting of hair during treatment of dogs.  Do not allow treated dogs to lick each other or rub against other animals until the application site is dry. It gives complete protection for one month from all harmful external-parasites. (Ticks, Fleas, Lice & mites)
