I would create a nice path (below large pavers with stone in between) from the front door to what seems to be the driveway on the left. Along the house you can really have fun with a perennial flower bed and choose the plants according to sun or shade. Where there seems to be a tree stump, you can plant a trio of either flowering shubs or trees, on the illustration I show lilacs which are available in different colours, white - pink - purple are nice together.

It's very tough to give advice when we don't know the size of your plants. The "3 azaleas planted that will not get very tall": what cultivar, when were they planted? If they've been there a while and that's their mature height, then either you should move them or plants something lower in front of them. Heather, maybe? If you just planted them and they should double in size bringing them up to the bottom of your window in a year or two, then you should plant low annuals, while waiting for the growth. Or moss Phlox at the edge. Plant bulbs. Daffodils are pretty resistant to critters, but tulips come in more colors. Ideally, you want color in at least 3 seasons. Hellebore does well in winter, moss phlox in spring, You can add a mountaint laurel in the shady section, that will bloom in the sprint. Sedum blooms in the fall.

Maybe you could share some yard pics that I could use to create some idea-renders if you like.

If this is the dog’s domain, you’re going to have a hard time growing anything small. Like groundcover, perennial flowers, or even grass, for instance. Unless you plan to set aside an area that he/she cannot access. Or maybe large containers for flowers. And I mean LARGE, nontippable containers.
