Dog urine contains high concentrations of nitrogen and salts that burn grass, leaving unsightly brown spots. In Zone 7, the heat of summer makes this problem even worse. Here are the 5 best grasses for handling dog urine in Zone 7.
1. Tall Fescue (Turf-Type)
Turf-Type Tall Fescue is the most urine-tolerant cool-season grass for Zone 7. Its deep root system helps it recover from urine burn faster than other grasses. It stays green year-round in Zone 7 and handles the summer heat better than Kentucky Bluegrass.
2. Bermuda Grass
Bermuda is a warm-season grass with an incredibly aggressive growth habit. When a dog burns a patch of Bermuda, the surrounding grass rapidly spreads via stolons and rhizomes to fill in the bare spot — often within 2-3 weeks in summer.
3. Zoysia Grass
Zoysia forms an incredibly dense, thick turf. This density means that urine is more diluted across a larger root mass, reducing the severity of burn spots. It also has a rapid recovery rate in warm weather.
4. Kentucky Bluegrass
Kentucky Bluegrass spreads via underground rhizomes, giving it a natural ability to fill in urine-damaged spots. It's best suited for the cooler parts of Zone 7 or areas with afternoon shade.
5. Perennial Ryegrass
Perennial Ryegrass germinates incredibly fast and establishes quickly. If you overseed urine-damaged areas in fall, Ryegrass will fill in bare spots within 7-10 days. It's often used as a "repair" grass mixed with other species.
Tips for Reducing Urine Damage
- Water the area immediately after your dog urinates to dilute the nitrogen
- Train your dog to use a designated "bathroom area" with a more tolerant groundcover
- Overseed damaged areas every fall with a urine-tolerant grass mix
