I know how it feels! i first time Layla got her nails cut by a non groomer... she jumped.. it got cut way too short... i rushed out to the pet store to get the powder and dipped her whole paw in
but i never washed it off it just kinda wore off. I won't cut them again... she goes to the groomers now for her nails... i just can't bear to hear her cry like that again! Good Luck
