I took my pups here because I'm from Hawaii and I thought "Hmm, aloha Pet Grooming sounds like a friendly-family feel place". I should have known the minute i got there when they practically dragged my dogs in by the leash. I understand my dogs were hesitant, because they knew they were about to get groomed... but at least take them back gently. When I picked them up, they looked ok... until i saw that my Bichon had had parts of the skin on his paw either shaved or cut off! it was the size of a good nickel! I complained, and they told me that it had already been there. I assured them that it was not there, as there was fresh blood on his fur.... and that they did that to him. I demanded parts of my money back, and I believe the guy called the owner or manager. She refused and we were going back and forth. In the argument, she somehow slipped and said that it was because there was a knot so big that when they chopped it off it grabbed parts of his skin. I told them that I was going to look into it deeply that they are held accountable for what they have done and without a hesitation, they credited me $20. It wasnt even about the money. They didnt even call me to or tell me about the cut and they knew what they did... and they had to lie about it. That's very bad. For the sake of your dog, please don't come here. I just read a previous review about the same thing that happened to another dog'. Thats just so horrible!
