I'm grossed out right now. I found a huge tick on my dogs neck yesterday. The day before I found 2 little ones not yet latched on. I use Revolution for heartworm. It says it controls fleas & ticks too. We don't have fleas. I hike in the local foothills 3 days a week & wonder if that's where they come from. Is there a product I can use in conjunction with Revolution to keep the blood suckers away? For now, I'm going over Arkane as carefully as I can after hiking & tracking too.
