It looks like a dogwood to me. It's been pruned heavily so it's hard to tell the original intended shape. Note the red twigs, though. Are there any little fruits on it?

Looks like dogwood to me too. You could prune your shrub to look like the tree. In a few years it will match it's height.

Thank you for responding so quickly - I took a few additional photos - there is a twig with a flower bud on the end (I haven't seen it ever flower but I've only been here a few months). I also took a pic of the back of one of the leaves. Does this help confirm its identity?

Looks like a dogwood getting ready to bloom again?

Oddly enough it does look like an inflorescence budding up. It should just be berries at this point rather than flowers. I'd say Cornus sanguinea now. A stressed one.

I looked online and there was a shrub for sale that looked just like it: Arctic Sun™ Cornus sanguinea 'Cato' - Red Twig Dogwood. I think that's it. How can I help it be less stressed? It's in a place that is difficult for me to get a lot of water to, and this summer has been dry and hot. Should I wait until it cools a bit and move it to a different area?

Are you in the Portland area? It has been hot and dry this summer. I assume that's most of why your plant is already showing autumn colors and is trying to bloom in the off season. This weekend when it's supposed to be cooler, give it a good drink if you can.

I am in Seattle but I think we are having similar summers...it's been so hot and dry! I am wishing for the rain (never thought I would say that)...

And thank you for your advice - I am a newbie gardener
