Hedging plants, clay soil, dog friendly!

[Lovetodaydream]

Hello!
We have recently moved into a property with a small garden. At the moment, it just has fence panels and I would like some all round greenery. We had red robins in our last garden but they were very bushy and may make the garden look smaller. Also, the soil here doesn't drain well, I think due to the high clay content.
Any ideas or am I asking too much?!

Don't think I can think of anything that doesn't get bushier over time. You can allow red robins to grow tree like, so bare on one or two stems rather than bush at the bottom. Then plant maybe smaller bushes below them.
I know they grow well in clay.
I have deutzia in the garden but it is deciduous but grows on longish stems rather than bushing out. My buddleia globosa has kept it's leaves but grows v fast, but would take hard cutting back.
Maybe shrubs on one side and climbers on the other?

Pyracanthia can be trained to be pretty flat. Just shove in a bamboo cane and tuck the branches behind it. Keep doing that as it grows. It only needs one or two a year.

Climbers sound good too.

Oh a climbing rose might be good.
