Does grooming stress your shih-tzu out?

I personally don't take my dogs to a groomer simply because I worry about how they would be treated....and where I work, they do grooming there. I've been suspended on more than one occasion for taking a dog from the groomer due to how the dog was being treated. If your dogs are acting odd after being at the groomers, demand that the groomer allows you to stay while the dog is being groomed. Some will not want this since dogs tend to act up a bit more when their owners are standing there, but some do allow it. So, I learned to groom my own dogs- it took a lot of time to get everything really figured out, and then I had to buy the grooming equipment- clippers & blades, nail trimmers, ear cleaner, scissors, brushes/combs etc., but I know that my boys aren't being mistreated by someone- and I don't have to pay the grooming fees lol
