My Oster dremel works great. Sunday is nail dremeling and tooth brushing day, both my labs lie down and a foot at a time is done

followed by teeth. They're really quite good about it and lie nice and still but I started with Ella when she was 8 wks. old. I also started the routine with Charlie as soon as we got him. With Charlie it took my son lying next to him gently clapping on his chest or head to keep him distracted while i did his nails. Ella held still nicely from the get go with treat bribes. Their nails are nice and short, nowhere near touching the floor and nice and smooth, so no scratches on us or the wood floors.
