So, My dog is 11 months old. I just finished her last dose of flea and tick control. It was the drops that I had to apply onto her back. Today, I found a flea. Not sure how they look like because I have ever encounter one. It was reddish in color. It was pretty quick at hiding but I caught it in time. Did hours of research and I thought it's best if I start by trimming her poor hair. It's very knotted due to butting and scratching. Would it be okay if I trim her hair for the winter? I guess I should really talk to my grooming salon but I would like to see pictures yorkie hair cuts 

 Share some please and any ideas of how to prevent Fleas?
