Hi, I have a 10 month old female jack Russel and in am wondering "how old does she have to be before she goes on heat".
please email me back asap as I also have a jack x fox terrier that is nearly two. is there any contraception that i could give her, as I really don't want her to have babies yet. she is to young, also how old is a good age for her to have babies with a great chance of all healthy one's including the mother.i would greatly appreciate if you could email me quickly. thanks heaps.
