Does anyone have recommendations for a good tick/flea product? My dog is 7 months old. He is an indoor dog, but is walked outside in a large field bordered by woods twice a day. As soon as it gets a little warm out, I have found ticks on him, and on me to. I can't even imagine what spring and summer will be like! I have tried Nature's Guardian all natural spray but it stinks and I'm not sure how effective it will be.
