There's a strange split in a lot of homes between how much thought goes into the sofa and how little goes into where the dog's bed ends up. Usually it's whatever fits in the gap left over, in whatever colour it happened to come in, shoved somewhere out of the way rather than actually considered as part of the room.
The easiest fix is colour. A bed or blanket that picks up a tone already in the room, rather than clashing against everything else, instantly reads as intentional rather than incidental. It doesn't need to match exactly, just sit within the same general palette as the cushions or the curtains, and the whole room feels more cohesive for it.
Placement matters more than people think too. A dog bed tucked into an actual corner of a room, rather than plonked in the middle of the walking path, tends to get used more and looks considered rather than accidental. Dogs generally prefer a spot with a wall or furniture at their back anyway, so this works for both of you.
Storage is worth thinking about honestly. Toys scattered everywhere read as clutter, whereas a single decent basket or box, kept somewhere accessible, turns the same pile of toys into something that looks deliberate rather than chaotic. It takes about thirty seconds a day to maintain and changes how a room feels considerably.
Feeding stations deserve a bit more thought than most people give them. A raised stand or a simple mat under the bowls stops water splashing across the floor and looks considerably better than bowls sitting directly on tiles. It's a small upgrade that costs very little and improves a corner of the kitchen that otherwise tends to look neglected.
Lighting is worth a small thought too. A dog bed tucked into a actually dark corner rarely gets used, however nice it looks, since most dogs prefer somewhere they can still see the room and keep half an eye on what's going on. A spot with a bit of natural light tends to earn far more use than a beautifully styled but poorly lit corner.
Textures are worth considering alongside colour too. A woven or knitted texture on a bed tends to sit more comfortably within a room full of soft furnishings than something with a shiny or overly synthetic finish, which can read as slightly out of place against everything else.
Think about scale too, not just colour. A bed or basket that's proportionate to the room, rather than either too small to register as intentional or too large to sit comfortably, reads as considered in a way that size alone can quietly undermine if it's badly judged against the rest of the furniture.
None of this is about disguising the fact that a dog lives in your house, nor should it be. It's about making the objects a dog actually needs sit comfortably within a home you've put thought into, rather than treating them as an afterthought bolted on at the end. A little intention goes a long way, and it usually costs nothing more than the swap you were going to make anyway.
