Yumega will help, but really, how long does it take to brush a pug? Grooming your dog is part of everyday care, and mine all get a rub over when we are watching tv or lying on the bed.
When I had my first GSD I was discussing this problem with a policedog handler and he said he added a spoon full of cheap oil to his dogs food and I still do this with Max, I've not noticed any difference in the moulting but he always has a lovely coat. As lankela grooming is the answer.
