Any idea what these are?

Does anyone know what this weed is? We keep getting them in our yard. The seeds on them are very sticky and stick to my dog. Sometimes she comes in the house covered with them and they're hard to get off. I have to use a flea comb to remove them. We've tried weed killer but that only kills the weeds around them. The only way we've found to get rid of them is to pull them and they are spreading like crazy. Any suggestions are greatly appreciated.

Maybe trifolium procumbins. A form wild hop.

I found out what it is. It's Drlymaria Cordata. A kind of chickweed. Thanks anyways.
