Neutering improves the general health of your dog, whether male or female. Likewise, it can eliminate associated risks to your pet’s health, such as some types of cancer and deadly infections.
In the case of your female pet, she will have a longer and healthier life. Spaying eliminates the possibility of malign mammary tumors in about 50 percent of dogs. Also, spaying your female dog prevents uterus infections such as pyometra, which can be very expensive to treat and potentially fatal.
At the same time, neutering your male dog prevents testicular cancer and some prostate problems.
Besides, neutering can prevent behavior problems such as scent marking and straying.
Neutered males are less likely to show aggression towards other dogs.
