It’s actually a nice space with plenty of options. Do you watch television in this room?

Train the DOG. Put the sofa perpendicular to the windows, and flank the fireplace with two chairs. Clean up all the stuff on the mantel. Find some inexpensive bookshelves, storage/ for the wall opposite the window, and get a couple standing lamps next to the sofa.

Or put the sofa UNDER the window, and use the chairs angled, and flanking the fire.

Try both, clean up the entire room, and re post some pictures.

Could you please draw a floor plan? Then we can help you best. Right now we don't have enough information to help you. In general, when you have a long narrow room, it's best to create two areas. In this case, perhaps a sitting area and a play area. Areas can be defined with rugs, furniture, and wall decor. You will need storage. Lighting - a ceiling light does no one any favors. Much better is a table lamp or wall sconce in each corner at chest height. Thank you.

Thanks for your help! It’s probably not that tricky for most people, but I just haven't been able to visualize how to put it all together.

1. We have a TV, but we don’t watch it.

2. Here‘s a rough sketch of the floor plan. I love the idea of having two areas, and that’s kind of how I have it set up right now.

3. We are working on training our dog, but it’s definitely a work in progress.

Your best furniture option for this home and any future ones is a 3-seat sofa and two upholstered armchairs. Keep these moderate in size; no puffy faux leather man cave pieces. Even though you don't use the FP, I would flank it with the two chairs and hang a nice piece of art 5" above the mantel (keep art no wider than the firebox opening below.) Then float the sofa centered on and facing the FP. Put a sofa table behind it and a coffee table 18" from it, or adjust enough so that both chairs can make use of the coffee table too. That will leave half of the room for a play area for the child and dog. You can probably find a large piece of casegoods in oak second hand. That can go on the wall by the door and serve as a counter balance to the FP. Maybe a big bookcase will work. Be sure to anchor it to the wall so it doesn't fall on your toddler or dog. After that, a lamp for the sofa table and a floor lamp by one of the chairs should do nicely.

This is so helpful! Thank you!
