For pet owners who let their dogs and cats into the backyard, the smell of a pet's latrine can become overwhelming, particularly during hot summer months. Although the smell of a pet's stools can be taken care of by removing the stool from the garden, pet urine often soaks into the ground and can linger in the soil. But removing the smell of pet odors is simple.
Locate the source of your pet odors. Most animals prefer to go to the bathroom in the same location each time. Others will mark their scent by urinating in the same locations.
Soak the area with a garden hose where you find the pet odor. According to Texas A&M university, adding three times as much water as urine to soil has a fertilizing effect as well as diluting odor. Water must be added to soil within eight hours from the point that the pet urinates on the soil to achieve this effect.
Test the pH of garden soil that has been soaked with dog urine with a pH testing kit. The testing solution will change hues based on the pH of the soil. Typically dog urine adds nitrogen to soil and makes it more acidic.
Mix lime into the soil based on the results of your pH testing kit by sprinkling the lime on the surface of the soil and raking it into the dirt. Lime will help nullify the ammonia smell associated with pet stains. It will also help to balance the pH in the garden.
