I used to be really good and brush Armani every single day- then I got lazy I guess- partially because they behave very very badly when I brush them- it was such a struggle all the time- I either need a second set of hands (not easy when you live alone) or I have to muzzle them for their own protection- so I went down to a few times a week (sometimes less)- they do get a few mats on their legs, under their belly, and in their armpits- but otherwise they are pretty much okay. They also go to the groomer every 6 weeks (used to be every 8 weeks, but I started going more frequently when i stopped brushing as well) She always says they are fine- so I guess its not too bad. When I strike it rich (hit the lotto, become a trust fund baby, marry rich, etc) they will just go to the groomer weekly for bath, brush, blowout and I will be done with my grooming duties for good
