We ordered 3 tubs of Nutra-Thrive for our 12 year old mixed blood hound mix to help with her bad breath. We brush her teeth daily but she still has this fishy smell in her mouth. She just started on her 2nd tub but the smell is still there although it's a bit less strong than before. Otherwise, she's healthy - great silky coat and energetic. If there's no further improvement, we will be discontinuing the product.
