If you are a teacup yorkie owner and you have an absolutely climb-proof and dig-proof run within your yard, it may be safe to leave your teacup yorkie bitch in season there.
But then again it may not be a wise idea, as there have been cases of male dogs mating with female dogs right through chain-link fencing. Just to be on the safe side, shut her indoors during her heat period and don’t let her outdoors until you are certain your teacup yorkie female’s heat season is over.
Never leave your teacup yorkie bitch in heat outdoors, unsupervised.
If you want to prevent the neighborhood dogs from hanging around your doorstep, as they inevitably will do when they discover your teacup yorkie bitch is in season, take her some distance away from the house before you let her do her business.
Otherwise, these canine suitors will be attracted to her by the arousing odor of her urine and they will know instinctively that she isn’t far from her scented “spot”. If you need to walk the teacup yorkie bitch, take her in the car to a nearby park or a field for a chance to exercise a bit.
Remember that after about three weeks – and this varies from dog to dog – you can let her go outside the house again without worrying that she can have puppies until the next heat season.
If you are seriously considering breeding your teacup yorkie, talk to as many experienced yorkie/teacup yorkie breeders as possible and read up on the subject in specific books and articles.
Only when you are fully aware of the demands and responsibilities of teacup yorkie breeding should you make your final decision. It must be stated here that there is no shortage of fine teacup yorkies in need of good homes, nor is there likely to be in the foreseeable future.
So, if your object in breeding is merely to produce more dogs – you are strongly encouraged to reconsider your objective.
It is usually best to breed your teacup yorkie bitch when she comes into her second or third season. Plan in advance the time of year which is best for you, taking into account your own schedule of activities (vacations, business trips, social engagements and so on).
Make sure you will be able to set aside plenty of time to assist your female teacup yorkie from mating her up to the time she gives birth.
