Getting rid of yellow dog spots on the lawn starts with your dog. Training a pet to eliminate waste in a selected spot in your yard can keep the damage confined to one area. Then you only have a small spot to repair. Or better yet, create a gravel or mulched area where your pet can relieve himself. When the dog signals he needs to go outside, leash him and walk him to the specific area. Use a command phrase (something short, like “potty”) in a commanding tone and wait for him to do his business in the desired location. Afterwards, reward him with vocal praise and petting, and a treat, if needed. No matter the age of the dog, this may take some time. Be patient and encourage your dog to use the selected area. After he begins to use the same spot, you can let him go without leashing and directing him.
Sometimes, though, you can’t teach an old dog new tricks. In these cases, consider constructing a dog run or dog kennel in your yard to keep your pet contained where both he and the lawn can be protected.
