I was in your shoes (had dogs all my life - they never needed more grooming than a bath) and had to learn from scratch. You should start on day 1 - at first just turn on the clipper and run it with the wrong side up along the body. 20 seconds if that - and do that as often as you can. The first time you use it do it on the body. Ideally your pup already had its face and feet trimmed at least once at the breeders. My breeder sent me a video of him having his face done - which helped me to see that he was fine. Mine is more ticklish in his feet than on his face, but I was more freaked out about doing his face than his feet... I was grooming with my hands shaking at first - and calming myself and him with this sing-songey voice singing along- it was quite funny - but I got used to it and he got used to me doing it. Don't show that you are scared so your pup does not pick up on it! Friend on my said to shave my legs with the clippers so I can see there is almost no way to cut yourself (and if you do it is just a nick like with shaving - it really is no drama at all). I watched every video I could find on here and on YouTube and it helped a lot! And ask questions - lots of very knowledgeable and helpful people here..Thank you for this info. It's very helpful. I find myself checking PF almost every day now For someone who has never used clippers on a dog, would it be wise to even try grooming the face and feet?
