Well, I'll give you my advice as the owner of a grooming shop, but I'm sure you won't like it and will have plenty to say about it.

My advice is - take your dog to a professional groomer and have it done right. "Home grooms" almost always look ridiculous. A professional groomer is just that - a professional.

You wouldn't take a pair of scissors and start chopping off big chunks of your own hair, would you? Of course not, you get your hair cut by a professional stylist, who is trained and has years of experience. Why would you think it would be any different with your dog?

Have it done right, by a professional.
