It’s hot and dogs are smart. They want shade and we can provide it or be warned, they may figure out something on their own. A lot of dogs left to their own devices in a treeless yard will dig a hole under your nice big hydrangea or other shrub and lay in the cool earth in shade. This may work out just fine for your pet but not your plant!
If you have a big yard you probably have at least one big tree so you have shade. If you have a small landscape it gets trickier.
Small trees for full sun that provide shade:
Katsura H. Globe has medium sized heart shaped leaves and casts light shade. (Eventually 15′ – 20′.) I’ve not seen it this big in the Pacific Northwest.
This Crape Mrytle has a thick leaf and can cast a heavy shade. Beautiful flowers, bark and fall color make it a favorite. (Eventually 20′ tall and wide.) I’ve not seen it this big in the Pacific Northwest.
If you select Strawberry Tree Arbutus Unendo ‘Compacta’ be sure to purchase the compact variety. It is my top choice for heavy cooling shade for a small yard. I’ve seen this as a 15’x15′ vase shaped tree after ten years. Please note, too much summer water will kill this durable evergreen.
This large shrub/small tree has large leaves and is great for dog shade. This plant is in Norma B.’s landscape. It was planted in 2013. It can be a 15’x15′ tree but typically is kept 10’x10′ with pruning.
