Hello Guest,
You might want to slow down and have a think. From what I understand, most breeders take their time in choosing the
best stud dog for their bitch so that they can improve their line and not exaggerate faults. Have you considered contacting your bitches breeder? She may be able to give you some guidance so you can make the best decision for your girl. Your bichon will have another season in a few months time and any serious buyers you have lined up should happily wait till she has her puppies. :)
If you want to do a bit more research into the whole breeding thing, I've provided you with a link below. Good luck! :)
