I dont think there is any need to take him so early, unless its just for a bath etc,
We took Riley for the first time last week and he is 4 1/2 months old, even then I only wanted his paw hair trimmed, his bottom area slightly trimmed and she did a bit on his head too.
He is however been brushed every day since we got him.
I have a soft ball slicker brush and a spratts 76 comb which COL peeps recommended.
