I have a male dachshund at 18 months old. Two weeks ago, I got a female dachshund 7 months. Old. We took her to our vet and everything was great except her vulva was swollen. Her very 1st heat. Three days later she began to bleed. Today is the? 14th? Day. I had bought her a panty which ties on both sides and has a pad in it. They have always played well. They like to get something(paper,toy,etc) and run and chase each other. When they were running in the room I had noticed she had something in her mouth. I got it and it was part of the plastic that held her pad in the panty. I then looked and saw she did not have on her panty and within 2-3 minutes found it. I called them over to give them a treat to keep their minds on treats! Then as I looked in the fridge for just a moment, I heard some scraping sounds, I turned and saw him humping her. Now, just know that he has never ever been close! He has never even had his penis out except just the tip. We tried to breed him with another dog before and he did not have a clue! He tried to go in her side. So I was VERY surprised to see him on her that close! I even moved his leg to see if he was in her. He WAS! Then they were tail to tail. I was so scared. I did not want them to do it, she is too young! I petted them and consoled them and finally his penis went down and he was able to release her.
What to do??
What are the statistics that she will get pregnant this very first time and when they were interrupted? I am so afraid for her. She is very long and so is he. He weighs 12 lbs and she 9.3. Should I call her vet on Monday or adapt a wait and see attitude?

Why oh why haven't your dogs been neutered? It can be done when the pups are very young. You have risked her life. I'm quite upset with you.

Yes, she could be pregnant. (Didn't you think two dogs would be able to figure out how to have sex?? )

I plan on her having puppies after her second heat. I have read and know what could happen! That's why I am so upset!! I know the risks. I wanted to know if someone knew the statistics of getting pregnant at this age and being interrupted.

I do not need for you to berate me and think you are without sin! This was not planned.

I have watched them carefully and have noted that she would attack him every time he made an advancement. I have had 2 back surgeries and I had just turned and looked into the fridge. I did not expect him to get it right this time because we had to try holding him close to the other dog and he just did not get it. However, I still took precautions of placing her in her crate in her room with the door closed if we had to be absent for any time.

But thanks a bunch for your criticism, it did not help at all. This was my first time on this question/answer. It everyone answers like you it will probably be my last!

Two unneutered dogs, with the female in heat, and you turn your back. What did you think would happen? They would wait for your permission?

I'm sorry if you think I am mean. I have volunteered for years at an over-crowded cat shelter that is full of unwanted cats. People dump them off at the back door at midnight after putting cats in unsecured cardboard boxes with a hot dog to eat. One fellow came in with his girlfriend who wanted to adopt a homeless cat. He told her that, if it didn't work out, he would bury the cat in the dirt up to its neck and run over it with his truck. Unwanted dogs at the county animal control site are euthanized daily.

Dogs and cats that are not neutered end up producing more dogs and cats. I could tell you more horror stories if you have time.

Part way through mine, I decided to end rude responses. This will save others the time to prepare a proper response to you while staying within the rules here.
