I'm 14 stay at home almost all the time I leave the house 2-3x a week for only 2-3 hours at a time I have done a fair amount of research about them and my parents are fine with it but

I already have a dog but she is older and sleeps for the most part two ferrets and chickens I think i have enough time for a puppy and I am very mature so I know it will be taken care of but I'm worried that I already have enough pets that I should just be happy with what I have which I am and I'm afraid I won't really be happy white a new puppy I want it more I am afraid if I get it I will ignore my other responsibility but on the other hand i have watched family's animals and still had enough time so my question is from this should I get this puppy or should I just wait cause I already have enough animals
