even though my vet recommended using a flea collar on my girls, I won't do it (she had said to put it on when going outside, then take it off when coming in.....which seems like it defeats the purpose based on the manufacturers directions). My girls play and bite each other and would therefore mouth the collars not to mention I have kids and I don't want them touching that stuff. We are using Revolution but for the summer are adding Parastar plus to it in order to fight the massive amounts of ticks we have right now |
