We were at FW over the Christmas break and our dog got several ticks on her. We went out and purchased a tick collar. Smudge has short fur so noticing fleas and ticks were easy. This was the first time travelling with her in the winter and I did not think ahead to know there would be a problem. We have a future leaderdog puppy living with us for a year. She's an (long thick hair) 11 month old german shepard. We won't be able to notice ticks on her. What product would other pet owners suggest/use?
