The size of your male alone is not a good indicator of what size female would be best for him as a mate. You have to take into account the size of the other dogs in both his and her lines as their genetics attribute to what is passed on to litters as well. (That's without even delving into all the many aspects that need to be taken into consideration when contemplating breeding.)
If you are aspiring to breed your little one and striving toward being an ethical breeder as oppose to your run of the mill BYBer, then you no doubt have a breeding mentor that you are working with at this point to help prepare you for what lies ahead. My advice would be to utilize his/her knowledge while you can! As you are just starting out, your mentor will be a valuable asset in helping you to select a good match for your guy and learning what to look for when pairing up dogs . |
