I've always been a little afraid of trimming my dogs nails for fear of cutting too short. I have 2 small dogs and their nails grow fast, so I finally decided it was time to learn because paying to have them trimmed so frequently was too expensive. This grinder came with information on how to trim the nail which made me feel more confident. The grinder worked great and it was my first time using it. I was able to use by myself without having someone else hold my dogs. Both of my dogs did really well with the grinder. I allowed them to get adjusted to the sound first and rewarded them with treats throughout the process. The wiggled a bit at times, but overall stayed still and allowed me to trim. I love how quiet the grinder is. I included a video so hopefully you can hear that it is quiet. The video was taken after I had trimmed my dogs nails and as you can tell they were not fearful of it at all afterwards. Highly recommend!
