Aphids, or simply plant lice, are tiny little insects that feed off your plants. They are 1-10mm long and once you spot them they are probably with many.

Aphids cause malformed flowers, leaves, and fruits on your lawn plants. If your lawn has an infestation of aphids, you can spray infected plants with diluted soap water, then with clear water. Concentrate on the infected areas of your plants’ stems, buds, and leaves. This technique works with even the strongest aphid infestations. 

Alternatively, you can set out ladybugs to get rid of them, ladybugs are a natural enemy of the Aphid. 

Frogs and toads are generally good for the lawn, especially since they feed on the lawn pests. However, too many toads on your lawn can be a problem. You can keep your toad population low by removing any containers of standing water, as well as any wood planks or pots where they can hide. Keeping your pet’s food inside the house may also help, because dry kibble can be a tasty treat for toads. 

The lawn is a nice place for your dog to play around and lay in the sun, however, you should not leave your dog on your lawn when you're away. 

When your dog urinates on your lawn, the affected grass often dries out and doesn't grow back. If you catch your dog in the act, you can easily flush out the area with water or add horticultural lime on the affected area to neutralize the urine. However, severely damaged areas may require reseeding.

Keeping an eye on your dog will ensure that both you and your dog will enjoy your lawn for time to come.
