Welcome to YT. Fleas are very hard to get rid of, you are vacuuming every day which is a must. Empty the contents of the vac outdoors into a plastic bag, tie the bag and put it in your outside trash pail. Buy flea collars, cut them into 3 pieces and stuff them in between the cushions of your sofa, do not put any flea collar pieces into your dogs bedding, you do not want your puppy or other yorkie to eat or lick a flea collar. I had a 10 / 11 year old that had fleas, my vet advised Comfortis, it's a pill form. I don't know with a puppy if Comfortis can be given, you should check with your vet. Keep vacuuming and emptying vac outdoors into a plastic bag, keep washing the bedding and use the flea collars stuffed in between the sofa cushions, make sure the dogs cannot get at the collar pieces you have stuffed in your sofa. Good luck and please keep us posted.
