En-Dex 8000 - problem

[isanbirder]

Preventic collars are made by Virbac, which is based in Nonthaburi. When I asked my vet for them she said she would order them, and mail them to me, and I had them within a week. That was a couple of months ago, and I haven't used them yet, as we have had no ticks so far this year (well, about one a week). I shall put them on fresh when the invasion comes with the rains.
