The lake was frozen, so the dog was crossing solid ice

Insects are able to walk across bodies of water without sinking because of their weight. Insects weigh literally nothing.
there are micro hairs that are almost water proof
Hydrophobic, meaning they repel water, which helps the water strider stay afloat. This allows the insect to utilize surface tension to stay on top of the water while moving.
they are neutrally buoyant. they have ballast tanks to achieve this
fast enough to run on water without sinking.
Insects that have the ability to walk on water have feet that are spread very far apart. This allows their weight to be distributed over a larger area and stops them from breaking the surface tension of water molecules sticking together.
not iron
They dissolve by sinking in to the water.
The weight a water bottle can hold without sinking depends on its size and buoyancy. A standard 16.9-ounce (500 mL) plastic water bottle can typically hold about 1 pound (approximately 0.45 kg) of additional weight before it risks sinking. However, this can vary based on the bottle's design, material, and whether it has any air trapped inside. Always consider the specific bottle's characteristics for an accurate assessment.
If an object with the same density as water is placed in water, it will remain suspended at the same level without sinking or floating. This is known as neutral buoyancy, where the object's weight is equal to the water's buoyant force, resulting in it neither sinking nor floating.
surface tension. This property is caused by the cohesive forces between water molecules, which allow the insect to stay on the water's surface without sinking.
