When's the best time to spay my chihuahua puppy? What about weight?
Updated On September 23rd, 2025
Pet's info: Dog | Chihuahua | Female | unspayed | 4 months and 16 days old | 4.4 lbs
At what age should I neuter my dog? She's 4 months old, female chihuahua. I was told by one vet that she can be neutered at 6 months even before her first period. Another told me not to neuter her before she is 4 years old because she can gain weight and have health complications if she is neutered before she's 4 years old? What do you recommend for this kind of breed? And will there be any changes after she is neutered?

Having her spayed at 4 years of age is taking a big chance health wise, she will be in high risk of mammary gland tumors. i would personally recommend having her spayed at the age of 6 months, before her first period. changes you can expect is mainly weight gain, but as long as you are on top of it she should not become obese.

Happy Easter to you too! Normally, it's best to have female dogs spayed between the ages of 4 - 6 months, so she should be ready to have this done now. And yes, a spay is usually an outpatient procedure that does not require an overnight stay at most clinics - but you can double-check with your vet's office about their policy to be sure :)

You need to call and make an appointment with a veterinarian to have her spayed. If she has come into heat already, wait about 3 months afterwards to have this done. If she has not come into heat yet, schedule this asap. Make sure they offer blood work and an IV catheter with fluids for the procedure. I hope this helps and please feel free to post any additional questions.
