1. Reduces canine aggression

Desexed dogs have a gentler temperament; they become calmer, more focused, and bark less.

2. Prevents accidental pregnancy

Female dogs go into heat twice a year, which makes owners anxious; accidental pregnancies still happen and cause many other problems.

3. Extends your dog’s lifespan

Desexing surgery can extend a pet’s lifespan. This is because excessive breeding activity accelerates organ ageing and shortens a pet’s life.

4. Avoids cancers and tumours

Desexing reduces a female dog’s chance of uterine, ovarian and mammary cancers, reduces a male dog’s chance of testicular cancer, and lowers the incidence of prostate disease.

5. A gentler temperament

It reduces or completely changes bad habits such as roaming outside, fighting, marking everywhere and barking, greatly lowering the chance of getting lost, injured or catching infectious diseases, and making the pet’s relationship with its owner more harmonious and gentle.

However, after desexing a dog’s metabolism and activity level drop, so it needs fewer calories than before; you may need to adjust feeding portions to prevent your dog from becoming overweight.
