Can i keep dog of my friend for one week in my house ?as an emergency

I’m aware that since i’m muslim i can’t own a dog . However have situation and can’t find right answer . My very good friend (non muslim) owns small dog (2 month old ) which usually sit in barrier at home for now . She is traveling now and arranged with another friend to take care of the dog but that lady unfortunately didn’t care much and dog ended up almost dying in vet clinic so they needed to do surgery for him (dog ate some plastic while was with another lady ) . My very good friend is panicking as that lady couldn’t take care properly . She doesn’t have much money to pay for one week hotel and prefer for him to recover at home (she paid very expensive surgery just now for the dog ) .So she asked if i can help and until she come back from that travel take care of her dog as she trusts only me now . Is it fine if dog will be allocated in one corner in his barrier for this period ?
