I'm only able to comment on the grooming service I received here. I have another vet I love but that clinic doesn't offer grooming.
I took my teacup Maltese here for a trim. I keep her in the "puppy" cut as her hair is extremely fine and tangles and mats easily. She came out looking wonderful and happy. She was kept only a half day rather than the entire day required by others. They delivered exactly what I asked for at a reasonable cost.
I asked for her claws to be trimmed, which was done well. They also expressed her anal glands for free (usually costs an extra $10) because it hadn't been specifically requested.
She once had a bad experience at a groomer who was abusive towards her, at that time when I picked her up, she was so desperate to escape, she would crawl up into my neck/shoulder. This time she was very calm and sniffing around the floor, cool as a cucumber.
I will return without any hesitation.
