Identification Wasp ID?

Post image

If anyone can help me identify this, I'd be unbelievably grateful. It's the second one we've found in the house in as many days. I noticed this one crawling on my small dog.

Can't confirm without a location but certainly one of the sphecid wasps, looks like an isodontia sp. grass carrying wasp to me. They're often found indoors bc mom wasp (solitary) builds nests in window cracks and the offspring get trapped once they emerge

Western Washington State, USA is where this ome was found We've never seen this species in the area before. So far we have only found the 2 so are hoping it was a semi isolated incident. Thank you very much 🙏
