It is the high concentration of nitrogen that causes your dog's urine or fecal matter to leave behind a dry, yellow patch. The supplements work by binding to the nitrogen, diluting its effect on your lawn; other ingredients in the products have been engineered to reduce the smelliness of your dog's waste. Note that these treats are designed for dogs only; you cannot give these to your feline friends.
Lawn Guard comes in several forms: chewables, tablets and bites. All of these forms are liver flavored, so your dog won't mind wolfing them down. All of the products' main ingredient is Yucca schidegera; Lawn Guard also contains a wealth of nutritional B vitamins, green tea extract, biotin and probiotics, including Lactobacillus acidophilus and Bifidobacterium longum. These items help to keep your dog's coat healthy and shiny; they also ensure that your pet's nails will not become brittle or dull.
Directions for giving the supplements to your dog depend on the size of your dog -- for regular Lawn Guard supplements, a dog that weighs less than 10 pounds should be given half a tablet a day; 11- to 19-pound dogs get one tablet; 20- to 49-pound dogs get two tablets; 50- to 79-pound dogs get three tablets per day; and canines who weigh in excess of 80 pounds should get four tablets a day. When giving your pet the Lawn Guard supplements, if the dog gets more than one tablet a day, you should give him half the dose in the morning and half the dose at nighttime.
The company also manufactures an extra-strength formula of Lawn Guard made specially for bigger dogs. The people at Doctors Foster & Smith also give the following hints for keeping your lawn green: add extra water to your dog's food; water your yard daily, especially in areas your pet is known to urinate in; fertilize your yard less frequently and plant extra-tough greenery in your yard. Types of grass that are less vulnerable to urine's nitrogen content include rye and fescue.
