i have never givin neeka any flee treatment stuff, or any prevantative stuff nor do i even know what flees look like if she were to get them, we walk through tall grass, i take her camping and down to the river and i have never worried about it. is there something i should be giving her or is it more of a climate/regional thing? (like the winters here get to -40/50ish and im not sure flees can live in that temp)
