Hi Elle
he isn't in full coat - he is only 2 (Beamer is my avatar).
I have been using the pin brush I got from Petco on him. But I realize it is not a good brush. I brush and comb him every day (sometimes more than once if he has been "gardening"

)
What are the reasons for needing more than one pin brush? You say it is not a "one brush solution"
