Looking for a male dog

Looking for a male pup or dog that is house trained and potty trained. Has to be good with both male and female people and younger kids as I have a daughter due in may and want her to have a fur ever best friend. Just recently had a male dog but he was male aggressive and we didn’t get told by previous owner and paid 850 for him upon her refusing to give us our money back or to take the dog back. We have everything a dog needs now just looking for the dog ???? please lmk what y’all have thank you in advance
