None
Grooming
Low Maintenance

Borinquen Mastiffs require little grooming other that an occasional brushing with a bristle brush or hound glove. They should not need a bath unless they become particularly dirty. However, you will need to check your pet's ears a few times per month and clean out any excess wax using the tip of a damp cloth.

Additionally, when the nails become too long, you can trim the tips of them with a pliers-type nail clipper.

When trimming the nails, take extra care not to cut into the tiny veins that grow inside each nail. If you do cut a vein by accident, place a small amount of styptic powder on the nail to stop any bleeding.
