Holly Madison says her dogs have taught her how to be a good mother.

The former Playboy model - who is due to give birth to her first child, a baby girl, on Tuesday (05.03.13) with her fiance Pasquale Rotella - is very critical of herself when it comes to disciplining her beloved pets and believes they have helped her prepare for raising a child.

She told OK! Magazine: ''I've been critical with myself about the way I'm handling my dogs, and 'am I firm enough with my dogs and strict enough with my dogs and doing the best thing for them?' I think it's definitely a good preparation for a child. You can't compare a pet to a child, obviously, because it's such a huge difference, but we all have friends that we've seen take on a pet they can't handle.

''It definitely is a responsibility, and a hurdle you have to pass before being ready for a kid.

''I've been a little more of a disciplinarian with them than I have been in the past, because I've always been that sucker parent that's really lax on my dogs, like if they're halfway potty-trained, that's OK. But I've been starting to get more strict with them, because if I can't even control my dogs, how am I going to control my kid? I'm practicing on my dogs and getting strict with them, and I've been trying to get all their training down before the baby comes so that they're ready.''

Holly recently revealed that she is planning on consuming her placenta.

The 33-year-old beauty also can't wait to dress her daughter.

She said: ''I'm most excited about all the outfits, definitely all the girly things. It looks like it's so much fun to shop for a girl than a boy. [laughs] When you walk into Babies R Us, the girls' side pops out at me. I'm definitely a girly-girl. She already has a bigger wardrobe than I do! I've bought so many things. I'm very excited to be starting off with a girl.''
