questions I have bred for over 30 years...and honestly have never had a sterile male. It is not that common in a health dog. I had one female who was bred twice and no pups. Most healthy females will produce litters.
I do not offer an unproven male at stud. If the breeding misses I am fairly certain it was bad timing or the bitches problem..thatis why another service is offered. I have had only had 3 stud service females miss twice.
A male is not fertile one week and not the next,then fertile the next week.. if he is well. I have been told bad teeth and gum infections can lower the sperm count..but look at puppy mills studs..few ever see the vet for teeth cleaning an produce pups monthly. It is important to keep the teeth and gums healthy whether it effects productivity.
As to shipping semen from France or any other country besides Canada. I would not do it. I, perfer the quality of the Yorkies here in America. The English Yorkie is a quality Yorkie, but they are bred to carry their tails down and that is a big drawback in the Usa. |
