At this time of year the only pruning done should be shortening the branch tips to contain the size. So yes you can make it look tidier by removing what looks like the top 12 to 18 inches of the more gangly stems to give it a more oval shape. Do it with hand pruners, not a hedge trimmer.

These can be, indeed usually are, cut to the ground periodically when dormant to encourage new brightly coloured winter stems which are the main reason they're planted. If you don't do this you end up with a straggly green shrub with no particular interest.

==>>> why???? its the perfect setup ... you cant possibly be blamed for any of it ...

first.. its apparent.. or should be.. its a plant that has way too much potential to be planted that close to the house .. yes.. you can beat it into submission .. but i ask.. why ...

second.. take a lawn chair and perhaps some adult beverages.. and sit on every quadrant of the bush .. and try to figure out what it is accomplishing.. but more important.. what YOU want to accomplish with it ... are we blocking a street view out back ... a patio view to a neighbor on the right... etc ....

third.. could we accomplish your goals by moving it out 5 or 10 feet ... so it requires less maintenance... can grow into a nicer shrub ... or ...

4th.. should we just abandon ship in the next few years.. because you come up with a better 5 or 10 year plan???

foundation plants are planted to hide the foundation ... NOT ON THE FOUNDATION ... and clearly the prior owner had no concept of how big nor aggressive this thing would be.. when they planted a tiny shrub one foot from the foundation .. and no.. i really dont care about it hurting the foundation .. thats not the point ...

imo.. wait.. where are yo.. big city name .... imo.. not much is pruned or planted in july and august .... so you have plenty of time with the beverages and lawn chairs... to figure this out ...

if you think moving it is an idea.. it would be done around when it loses its leaves in fall ... or in dormancy in very late winter.. or early spring ...

soooo... plenty of time to figure it all out.. perhaps with the new house.. you have more important things to do right now ..

if you want more ideas about landscaping.. start a new post.. and give us broader pix... instead of just one corner of the house ... and we can give you lots of ideas to contemplate while sitting in those chairs getting liquored up .. lol ...

ken

ps: this is how i look at future potential ... not how large they can get.. but also how cool they can be when not scraping on the house ... round balls or red goodliness .. if properly cared for .. even if you do cut it down like flora suggests. its stick a red sore on the corner of the house... and since its a winter thing.. you probably cant even see it from the house when its red .. depending on where you are ... i mean.. really.. whos going to be sitting out there in the lawn chair with the beverages with snow on the ground ...

What floral said, but wait until next winter/early spring to do it. Red-twig dogwoods naturally have this kind of sprawling look after a couple years. I've seen them w/stems tied tightly together w/string or rope to reduce the sprawling.
