How soon can my shih-tzu puppy get pregnant?

I have a 5mo girl and a 7mo boy. Recently Jack has being trying to hump (for lack of better words) Isabelle (she's 5mo old and barely 5lbs.). I'm worried that she may get pregnant. Is this possible at such a young age. My vet said she will have her "period" before that is possible, but what if I don't see it, how will I know?

You will see it. Her vulva will start to swell, and she will bleed. But please spay or neuter your pets. Your female is way too young to get pregnant. She must be at least 2 before this is acceptable, but it can happen before. If you do not know what you are doing, please don't allow it!

    You need to get them spayed and neutered now. Pups can get pregnant before they are obviously in heat.

    Very young female dogs can get pregnant but it's very dangerous for them and you shouldn't allow it to happen. Some dogs have gotten pregnant as young as 5 months of age.

    She can get pregnant as soon as she has her first heat that can come any time from now on. Usually between 6 and 9 months, but it can be earlier or later. She is not old enought o have puppies just because she can have then. They should never have them until the second or 3rd heat.

    Get her spayed and the male neutered. it's better for both of them. If you don;t every heat you will be fighting to keep them apart in seperate rooms. The male will howl and drive you nouts. The will rip doors apart to get together. It's not fun for you or them.

    Put some hoop earrings on her and some of those wedge pumps and I'd say maybe 10 minutes or so.

    A dog can get pregnant during its first heat at about 6 months old. However, that would be like comparing it to a 12 year old girl who can also get pregnant after her first period. She is way, way, way to young to be bred. Spaying her is the very best idea, and get the male neutered. Please don't let her breed at this age. You will definately know when she goes into heat, as she will make bloddy messes everywhere, and your male will lose his mind! Don't put your dogs and your family through this, please get them altered. Thanks!
