Dog Damage on Sod: Grass Selection and Soil Amendment for Wet Sites

A 90-lb Lab will destroy any grass on wet, poorly drained soil in Nassau County. No grass variety withstands concentrated dog traffic on saturated ground. The solution is twofold: keep the dog off the lawn, and fix the soil.

Amend heavy clay soil at least 12 inches deep with organic matter—peat moss, sharp sand, compost, aged manure. No chemical fertilizers; they repel earthworms that naturally aerate and structure soil. Grade, then lay sod. Improved drainage reduces sogginess and increases wear tolerance.

If dog access is unavoidable, tall fescue handles traffic better than Kentucky bluegrass but lacks KBG's beauty. It's used on football fields for a reason. Still, neither survives daily large-dog activity on wet clay.

Never add sand alone to clay—it creates concrete-like hardpan. Use a balanced organic amendment blend.
