You are doing great !
A Resco has a blade and there is no crushing. This is another reason I have never let the Vet trim nails even though this is included in the monthly 'plan' of monthly payment to alleviate sudden shocks to the wallet.
My dogs got neglected during and immediately after hip replacement surgery so once I was fit enough, I dremelled them daily for a week before getting back to normal routine.
The 'up side' for them was more 'special biscuits' - rewards they get after nail cutting !!!
Snow is promised here but not immediately -
