Patience is a very necessary tool doing anything with a Bouv..they don't like to be rushed..and grooming one requires patience..so she has come into your life to teach patience..
I have had many comments about William and Magic before him..and the cut I do isn't really a Bouv style..but living in Az it is the clip I use all year long..And being that both are therapy dogs and need frequent baths it just makes things a lot easier to get ready for visits.
The best advise I could give you if you want to do it yourself is to find someone who does Bouv's on a regular basis and ask for a few lessons..the face and head take the longest to grow back for some reason..but I think that is what you want to concentrate on ..for that Bouv look..
It is well worth it..
And get professional clippers if you are going to invest in some..they will pay for themselves..
On William I used a 10 blade on his tummy and private area..
and a 4 blade everywhere else..
the best explaination is that I carve a dog out of the hair ..and I use the clippers Sissoring is not my best skill..the only dogs I was ever good at were poodles..
Blowing a Bouv dry they have straight hair and I just am no good at sissoring it..
It is pretty amazing what you can do with a 4 blade..and I made lots of mistakes even after a few lessons from a groomer that I got some lessons from for a Bouv.
Just remember that the difference between a good haircut and a bad one is...a couple of weeks..
