Do they have dogs?
I have a few in my back yard.....no dogs.. I'm thinking iron dificiency, the pH is off or both.
My guess, but the picture is terrible, creeping bent???
It is rough stalk blue grass. I just dealt with it in sod that I did in the fall. The sod farm is replacing it all for me. There was a bad out break this year. It seems to be popping up everywhere this spring.
The only thing you can do is wipe it out and reseed before it goes to seed.

Any ID from the photo above is a pure guess. Grasses are identified by using a turfgrass ID key, looking at the distinctive parts of the plant under magnification.
Roughstalk bluegrass, Poa trivialis, does not spread by seed in lawns - they never get tall enought to go to seed. The main reason for the spread of poa triv in mowed turf is contamination in seed lots. There is a market for poa triv seed, but the seed industry is moving to quarantine the installations where poa triv seed is processed, in order to prevent this contamination.
