We recommend using our Lawn Seed For Dogs Mixture . This mixture contains a high level of perennial ryegrass which has a thicker leaf than other grass species. This thicker blade allows it to flex and bend more times before becoming damaged. This is very important when you are looking for a lawn that will be hard wearing. The larger leaf area of perennial ryegrass also contributes to its resistance to yellowing from dog wee. These factors make it perfect for gardens with dogs that love to run around and play.
