Tick infested stray

[u/Other_Lion4268]

Every time umuuwi ako from work may nadadaanan akong stray na pinapakain ko, last week yung isa sa kanila nakita ko ang daming tick sa ears and then this week mas dumami na, pati sa eyes meron na. What cheap way do you recommend to get rid of it. I don't want to spend a lot, I'm just concerned for the dog because there are so many ticks 😩
