I own a Pet Motel Kennel in the downtown Los Angeles area. I kennel up to 80 dogs per night. I haven't found any landscape surface that will hold up to that many dogs except concrete to this point. However concrete can be to hot and not comfortable on the dogs paws. I wanted to find the best artificial turf system made for our kennel. After months of research I found Global Syn Turf and their Los Angeles distributor. They taught me everything I needed to know about dogs and their relationship with artificial turf. Their grass has three times more preamble than other artificial turfs on the market. This turf requires no water and very little maintenance. When the artificial turf is applied over concrete there is a drainage tile that can be installed to create an air pocket between the artificial turf and concrete to create better drainage. Artificial turf for pets minimizes mud and dirt inside my kennel, no need for chemicals and fertilizers, no real grass allergies and to top it off it is green all the time. As always it comes with a 15 year manufacturer's warranty. I recommend you call Global Syn Turf for all your artificial turf needs.
