Anyway our good news is......
My boy Logi and I took a trip to a specialist Vet who tested his fertility, he is still firing on all four cylinders!! He even has a certificate to prove it!!! Even more than that is the fact that he is so fertile that we have been able to store his semen for future use, he has had a request from overseas so he can now fulfill that request and will still have plenty for future use long after he has gone, which I hope wont be needed for many, many years.
Good news though for his two future wives in this country as they may be getting an older more mature man but they know he is as virile as ever!!!!
