Given the task definition, example input & output, solve the new input case.
In this task, you're given a review from Amazon's food products. Your task is to generate a rating for the product on a scale of 1-5 based on the review. The rating means 1: extremely poor, 2: poor, 3: neutral or mixed, 4: good, 5: extremely good.
Example: I have bought several of the Vitality canned dog food products and have found them all to be of good quality. The product looks more like a stew than a processed meat and it smells better. My Labrador is finicky and she appreciates this product better than most.
Output: 5
The user really seem very satisfied with the product and gave good review worthy of 5 stars rating.

New input case for you: Our dog loves this stuff. I bought it for a occasional treat since he only eats dry dog food, I thought it would be a nice treat for him to have a lil something extra every now and then. But this stuff stinks really bad like dirt, it makes the whole area where the dog eats smell like we just opened and bag of soil in the house. If they could improve the smell of it, that would be awesome, because our dog just loves it but we can't bare the smell of it.
Output:
