Mark, can you explain why nearly two year-old carpet with medium grade pad would smell so strongly of dog odor after being steam cleaned with the rotary steamer, enzyme pre-treatment and enzyme after treatment?

We have two dogs but their coats do not smell. When they do start to develop an odor we bathe them and it takes care of it. The odor after the clean is terrible. Overwhelming dog-coat smell. The cleaners came back two days later to clean again. They did not enzyme treat after the clean initially because there was no odor and we didn't have stains. They used the after treatment the second time. For most of the day, all we could smell is the treatment. Gradually, the smell started coming through the treatment scent.
