Could I kick my guy friend out if he just picked up my own dog after she made my own mother trip and fell on the wet sidewalk outside?

Legit my mother did not think about how strong my 1 year old puppy has in strength & she was running around the gated yard in the apartment area and the guy has a family that he currently does not live with yet he has been living with me and my mother since 2018 .
