Spaying and neutering offer many benefits, but there can also be some drawbacks. These vary depending on the type of procedure and species.
Dogs
Neutering (male dogs):
- Metabolism changes after neutering, and muscle mass may decrease, which can lead to weight gain.
- Certain behavioral issues, such as aggression or anxiety, can sometimes worsen. We therefore recommend trying chemical neutering first, which lasts about 6 months but has a similar effect on behavior as surgical neutering.
- In some cases, neutering can help prevent or treat tumors influenced by testosterone, but the risk of prostate tumors may actually increase.
Spaying (female dogs):
- Spaying changes the energy balance, which may cause weight gain.
- Spayed females are more prone to urinary incontinence as they age, though this can usually be managed effectively with medication.
- The coat of long- or medium-haired dogs may change after spaying, becoming curlier or duller, but this does not affect the dog’s health.
- It is important to monitor weight after spaying and adjust the type or amount of food if needed. Contact us for advice on diet or weight management.
Cats
Neutering & spaying:
- One downside is that metabolism changes after the procedure, which can lead to weight gain. This can be managed by adjusting the cat’s diet.
The benefits, such as preventing unwanted litters and health problems, generally outweigh the disadvantages. Your veterinarian can advise on the best timing and measures to minimize any drawbacks.
