Most flea and tick medications should not be used until 6-8 weeks of age and will say the age on the package. If you are having a flea problem I recommend using a flea comb to comb out any fleas. I dip it into a bowl of water with a drop or two of Dawn dishwashing soap. This will kill the fleas. As far as ticks go again I would just check Princess over daily and remove any you see with tweezers. When you go in for her first vaccinations at six weeks your veterinarian can help you decide on a flea and tick product that works well in your area and is safe for small dogs such as Princess.

    Congratulations on your new puppy! Flea and tick medications can either be oral (such as nexgard) or topical (advantix, frontline, parastar, vectra). You can choose either based on your personal preferences and what you think is the best option for her. I would reach out to your regular veterinarian to see what options they carry and the pros/cons of each. Based on her age, she may be restricted by age and weight for those she can start. I would decide which type you would like to try, and then see when it can be started based on the label recommendations.
