I have a white toy Maltese. He has a kind of long hair which always gets tangled up. Many times I have tried to untangle it bit it is really difficult and nothing has worked for me so far. So I have to take him to the dog groomers every month. They get it done. Sometimes I wonder how dog groomers untangle dog hair. Can someone help me regarding this? What all do they require to get it done? Even if someone has some personal suggestion can come up with answers. I would really appreciate it. Thanks.
