Thank you.Variety of poodle is determined by the parents size, so if they were toys, she's a toy. If they were mini's, she's a mini. If they were one of each, she's intervariety, and I'd just call her whatever size she reaches .
Toys can go oversize as well as smaller, and mini's can go oversize as well as smaller. There have been a few times thru post Victorian breeding history where the varieties were crossed to breed in or out certain features so that genetic history can crop up occasionally.
Re Heat cycles, the 6 months is a generality. Small breeds can go into heat more frequently and it may take several cycles to regulate. After the first heat is an optimum long term health window for spaying, fyi.
