can you cut the hair some?

I have a dog like this and you can cut the hair and you need to brush it often and give it a bath every two months or so

Best let professionals handle the hair cutting. You need to brush him daily, and get a good comb to keep him from getting mats. I use a spray on "No More Tangles" Periodically, and the dog gets a bath whenever he needs it.

Yes the Bichon should have it's hair cut and on a regular basis. They should be taken to the groomer in your area

im a groomer. yes you cut there hair pretty much the same as a poodle. the face is trimmed different and you dont shave the feet. you should have it grommed at least every 6 weeks. back comb (comb toward the head) a couple of times a week.
