Pet Walker

He is supposed to be a maltese, but he looks more like a maltepoo. He's under 20 lbs. I took him once to pet smart and I was so shocked. She cut him to the skin, knicked all over the place. I way over paid and I cried. He now has fur on his back and butt like a sheep, it's so rediculous and the rest of him his so full of matted areas. His toe nails are too long, I have any idea how to cut them but he freaks out. I am not cutting them too short which is the problem. Please let me know. Cheryl
