Spot-on worksike magic Or nexgard chewable tablet give him according to his weight and age ..once in a month.. Use continuously for three months

Buy Himalaya anti tick powder and apply 15 min before bath

Fixotic advance spray

I'll suggest Bravecto you can choose as per the size..but make sure you feed your dog light the day you give this ...for next 3 months or so no tick or flew will come close

I used notix powder... not all the ticks gonna die even after using the powder,you have to manually pickup each and every tick you find...then apply boric powder it will relieve the itching
