Hi Rhadi, hope this helps! https://www.cuteness.com/article/dog-stains-off-ceramic-tile
Nature's Miracle has a line of cleaners for pet stains. Match the formula to the type of stain.
In general, I clean my tile floors with the following:
1 cup baking soda
1 cup white cleaning vinegar
1 Tbsp blue Dawn
2 gallons hot water (I boil about 1/3 of mine)
For stubborn stains, I will use Lysol Lime & Rust Remover Toilet Bowl cleaner, comes in a black squirt bottle. I don't have pets but my step son's family lived in our farmhouse for a while and they did. This took out all the stains they left behind.
I came across this info that might help you:
Dogs provide companionship and love, all wrapped up in a cute little ball of fur. Unfortunately, dog urine can leave an odor that lasts for weeks and even months after the initial accidents. A variety of problems -- both emotional and physical -- will cause your dog to urinate outside its litter box, and a trip to a veterinarian may be in order. No matter what the reason, you can clean the dog-urine odor from tile and grout.

I have used Scrubbing Bubbles to lift stains out of flooring for years:
I just bought Odor Ban PH balance no rinse floor cleaner from Home Depot that is great for cleaning pet urine odors from tile. I have a 2000 sq foot basement and my old cat sprayed a lot down there so this has helped get the odors out. I had to order it at Home Depot and pick it up and it is less than $10
Purple Power from Walmart will clean the stains. It is in the automotive section and is around $5.00 for a gallon and can be used for a trillion things.
