Hi Please can anyone help here is my situation :
I have a jack russel x bitch (cassie) she lives in the back garden- 1 years old we have had her for few months
recently got new jack russel (jake) he is fully house trained and is 2 years old only had him a few days

the problem: Everytime they re together he tries to mount her and inpregnate her
                  she is not intrested and gets very wond up by him and so we have to seperate them.
                  he is due to have his manhood sorted out later this week
question 1 will he leave her alone- i think if he wasnt so sex mad then they would get on great
question 2 wil she need to be done- it is such an expenssive operation hence the reason why he is going first (£50 cheaper for male)
question 3 will she ever be able to live indoors- she cries when she is in presently to go out- she is not housetrained
question 4 will she resent him for living in the house as she lives outside?

summary
we have two children one of each- and jake is the better option when it comes to the family aspect as he is house trained can play easily with my little boy and girl. when we go on holiday- camping- jake can come with us as he is so well behaved and again housetrained.
Cassie we love- alhtough she is very wild and only my husband can control her- she will not walk on her lead etc likes to run free- but never runs away- my son and daughter cannot play as easily with her as she demands much more attention than jake- who is quite happy to sit and be strocked!
we are really confussed at the moment and dont know what to do- any advice would be really appriciated.

thank you

foxy

Is there a reason why Cassie lives outside?
Maybe she is getting over excited when she comes to play with the children as she isnt used to the attention whereas Jake is used to being inside with them ?

No she has always lived outside before we got her she lived outside

Are they both rescues?

yes

i have downloaded lots of stuff about introducing new dogs etc but nothing seems to cover my problem

Unless your bitch is in a secure kennel and run that another dog cannot climb, jump or diog into then you run the risk of her getting pregnant.

As to the males attitude are you sure the bitch isn't in season?  Many males can be a bit rampant with access to a femal even if she isn't in season, especially if she is not very bold.  Usualy after she tells him off for it he wills top being do over excited (unless of course she is in season).

Your bitch has obviously not been properly socialised and trained in her short life and you shouldforget that she is a year old and treat ehr as an 8 week old puppy.

Bring her indoors and housetrain ehr by letting her out every hour while she is awake.  Get her a crate or make her somewher that can be a den for her to ahve peace from the kids and the other dog.  If she has always been outsdie the hustle and bustle, smells and noise indoors will be alien and frightening/disconcering for her.

By exposing her to all this, but not overdoing it (leave her to her own devices, and let her come to you and the kids for a fuss only if she wants.  As she becomes more accustomed then she will want fussing more.  If she is being over the top with the kids then she needs to be totally ignored until she calms down. 

This will take a bit of work with the kids.

Referal through your vet to a reputable behaviourist or trainer expereinced in rehabilitating rescues will help you enormously as will reading good books about behaviour and how the dogs mind works.  go for titles written in the last decade as ideas have changed and evolved quite a lot.

thank you, so if i just start all over again with cassie then she will be able to be housetrained? 1 yr isnt too old?
should i keep the two seperated when im not in or even when i am in?

I would keep them seperated when no on eis there to supervise :)

No it isn't too late to housetrain her.

Only keep them seperated if she is in season.  Is her vulva enlarged, has she been bleeding at all in the last few weeks?

If he is pestering her then seperate them for time outs, but otherwise best to let them sort themselves out under supervision (assuming she isn't in heat).

If she is found to be in season get her to the Vet asap to have any pregnancy stopped, or if it is too long to have her spayed.

1 year old is definitely not too old to house train, maybe will take a little longer than a puppy though.  My rescue newfie was 5 and not house trained when he came to live with us.  It took roughly a week to house train him during the day but about 4 months for him to be clean at night.
