Dog wee can cause yellow or brown patches on lawns because it contains high levels of nitrogen and salts, which can “burn” the grass when concentrated in one area. While nitrogen is normally beneficial, these strong deposits overwhelm the turf and damage both leaves and roots. To reduce the impact, it helps to dilute the area with water soon after your dog has been on the lawn, encourage them to use a designated toilet space, and maintain a thick, healthy lawn through regular mowing, feeding, and overseeding. If damage has already occurred, affected areas can be raked out and reseeded to encourage fresh growth. While no grass seed can completely prevent urine damage, our Lawn Seed for Dogs mixture can significantly help the lawn recover more quickly and maintain a healthier appearance over time.
