tick problem

Hi everyone!
I need advise. Once a week i take my doggy for a forest walk. I’m very concerned about ticks. What do you use? collars, spray or smth else?

It is best to spray and some new collar and then it will be fine but the collar must be good because they are cheap but they do not fulfill the task I know because I had this problem and I bought the cheapest spray and my dog ​​did not have ticks

I only spray it and no ticks or anything else bugs cling to it

I also just spray the spray and there is no problem at all
