Ontario Spay and Neuter

This place is great! They were very thorough and all the staff I interacted with were super sweet and helpful. My little one had a neuter done and is healing wonderfully! I highly recommend and will definitely go back for his wellness visits in the future.

Love Ontario Spray and neuter they are so friendly and care so much for our puppy. Very professional and always giving us great information reasonable prices. Thanks for all you do for our Raider

I'm so happy with this clinic! The entire staff is incredibly kind and took great care of my kitten, Doja. We also left there with a bonus cat that was waiting to be adopted. She's so sweet and is a joy to have in our home!

Great prices , took my puppy to get neutered because everywhere was very expensive. Also the check ups are very affordable. My puppy loves going, never feels scared or unwelcome. The staff are very friendly and make our puppy feel safe. Thank you Ontario spay and neuter! They also offer treats

My kitty Mufasa was neuter today and the prices were just right! There's a big plus, they provide vaccines for your lovely pet. No over charge plus he got micro chipped and the best news no yearly bills! Thank you for getting the job done on the weekend! Great team Dr. They do need more front desk members in order to get clients in and out quicker!

This is a great place. They are clean, professional and welcoming. Rosa helped us in a gentle way and answered all our questions and concerns patiently. Thanks to them, our baby Xyla was back to normal in just a few days!

I made the right decision bringing our first Pet Midnight to Ontario Spay/Neuter. We had our fur baby Neutered. My daughter and I were nervous but we were soon reassured by all the explanation of process. Sure enough on schedule he was ready to be picked up as they estimated. The follow up and walking us through everything was exceptional. Definitely coming back for nail clippings, vaccines and all other services they have.

They fixed my rescued cat with no appointment. I just showed up before 9am and drop off my cat, I opted out for blood work and they fixed my cat same day. I’m a first time pet owner, it gives me peace of mind when they allow walk in neutering. FYI I tried calling/ emailing them with no response. Maybe just show up at the clinic is easier for any communication. Very nice staff at the front desk as well as the doctors care and pay attention to the animals. My cat healed perfectly thank you Ontario Spay and neuter.

The people who work here are amazing. The passion they have for the animals they are is definitely genuine. I come from the Pasadena area and will continue to do so for their amazing service. Thank you for taking care and loving my fur babies.

The staff at OSN are so great! They made me feel very confident leaving my baby girl in their hands. My little pug was well taken care of. It happened that my baby was in need of some unanticipated work done. They called and explained what was needed and they were able to take care of everything in one visit. I truly believe that they love my baby almost as much as I do. Thank you OSN. You did a great job.
