The reasons why dogs scratch tiles with their front paws:

1. When a dog is excited, he will scratch the tiles to express his mood.

2. If the dog’s nails are long and cause discomfort to the dog’s claws, the dog will grind its nails by planing the tiles. It is recommended that the owner trim the dog’s nails regularly.

3. When a dog is anxious to go out to the toilet because it is holding back urine or stool, it will tell its owner in this way that the owner should take the dog to defecate in time.

4. Some dogs with a strong sense of territory will leave their scent on the tiles by scratching the tiles to achieve the purpose of marking.

5. Dogs have the habit of pawing things, so sometimes they will also show this behavior of paving tiles.
