There are actually several lakes named Dog Lake in Utah. There are even two in the Wasatch (this one and the one accessed from Brighton). Dogs are allowed at this Dog Lake, but if you take this trailhead (from the Big Cottonwood side), dogs are not allowed on the trail (they are allowed on the trail that starts from the Mill Creek Canyon side).

The trailhead is the same as the one for Desolation Lake. At 1.8 miles in, you come to a junction where the right fork goes up to Desolation Lake and the left fork rises very quickly (i.e. it is pretty steep from this point) to Dog Lake. The lake is only .6 mile from this junction.

At the top (at the lake) there are several trails spurring off and you can connect to the Great Western Trail, Butler Fork, or several others, if you want to extend your hike. Otherwise, just come back down the way you started.

You can walk all the way around the lake for that few extra minutes of exercise and enjoyment.
