Not only population control of dogs but there are several other advantages of spaying/neutering dogs. Some of them are as follows: - Dog fight reduces. - Spaying prevents breast cancer. - Spaying prevents the nuisance of heat period. - Spaying prevents deadly infection of uterus. - Neutering eliminates the occurrence of testicular cancer. - Neutering eliminates the odor and markedly reduces the incidence of urine spraying.
We conducted spaying/neutering of dogs at the shelter even today. If you still think that sterilizing dogs is of no use, please go through above advantages carefully.
