Is it something like this?
Wahl Home Products | Battery Beard 9906-717
It looks like it has a #30 or #40 blade. That's surgical shave, very close. I use a #10 blade against the grain for their bellies & sanitary areas. #10 is 1/16" cut, #30 is 1/50" & #40 is 1/100".
Maybe Teddy is just xtra sensitive...might need to get a clipper that has different blade lengths. I have this one in pink & love it. It has 5 blades in 1, sizes: 9, 10, 15, 30, and 40. For blades, the higher the #, the shorter the cut. Also comes w/2 rechargeable batteries & a charging station.
