Canine Behavior/Yorkie pup


Hi I have a 10 week Yorkie pup I also have a 15 month dog Yorkie and I'm not sure when she come on season as I don't want my dog to breed as she will be to young 1st time thanks jennie

Some smaller breeds come into estrus late, it really is dependent on the breeding line (you might want to ask the breeder).  The first estrus can be "silent", meaning there's very little visible evidence.  The most obvious evidence is the bitch attending to her latter parts in a manner she doesn't usually, and small spots of blood might appear.  As the cycle wanes, the blood spots will be brown and the bitch may "flag": present her rear and raise her tail, if there is a male present.  If you suspect your bitch is in estrus, purchase special paraphernalia that will prevent any dog from breeding her:

BE VIGILANT.  She cannot be outdoors alone.  A veterinarian can do an estrogen titer (blood test) to determine where she is in her estrus cycle.

A 10 week old male is incapable of breeding a bitch successfully.  It's most likely his testicles have not yet descended.  But don't push your luck: if you don't want these two to breed (ever), but you do plan to breed the bitch (and you have done your homework: you have screened her from inherited diseases and conditions and understand that this is a huge responsibility, especially in a small breed, and that she CANNOT BE BRED to a dog much larger than she is), neuter the puppy as soon as his testicles descend.  He will still be able to "couple" with her but he will be "shooting blanks" (so to speak: :o/)

I have spent my entire professional life rehabilitating the behavior of the domestic dog and I can answer any question regarding any behavior problem in any breed dog. I have answered more than 5,000 QUESTIONS on this site in the past (almost) eight years. If you are a caring, committed owner and need advice, I'm here for you. I am personally acquainted with my colleagues (Turid Rugaas, Ian Dunbar, etc.) who were members of an elite group in EGroups that I founded: K9Shrinks. THERE ARE NO QUICK FIXES for serious behavioral issues; not only is it unprofessional to offer same, it is also unethical. IF I ASK YOU SUBSEQUENT QUESTIONS, I NEED YOU TO INTERACT WITH ME. More information equals more credible answers and a more successful outcome. If you want ANSWERS THAT WORK, participate in any way I request. I'm quite committed to working on this site for YOUR benefit and the benefit of YOUR DOG. Help me in any way you can.
