★ 5★ 4★ 3★ 2★ 1I have never been in a Petco store. Had time to kill while my car was in the shop and thought this was an opportunity to stop by. First, I was surprised of the store smell, it actually smelled nice. Fir what ever reason, I thought it was going to smell bad..I was wrong. Lot of food in this store..wowzer. Pretty cool to see dog grooming for first time. Had to go to the bathroom and it requires a key...attached to a huge metal plate....bathroom was clean, always a plus. Fish, birds, one cat, reptiles..a potpourri of wildlife in here...lot going on.....if I had a pet, which i don't, I would come to Petco.Support your local Petco store....
July 30 · George Toth Jr.I LOVE this store! So much to the point I will go out of my way to drive all the way out to go to this location(I don’t live close). They have the most amazing fish department of any chain pet store I have ever been to. Their fish staff, Jackie especially, are very knowledgeable and friendly and help you make the right decisions based on your tank and what you already have. I have bought pretty much all of my plants from here and they adjust wonderfully to my tank. They also have some more specialty type fish, and most of their tanks have lots of plants in them. They take great care of their fish!
June 18 · Sofia PajunenWe went to the San Marcos Petco for grooming for the first time 4/25/25 and will NEVER go back again.We stayed around the area for the duration of our pup’s grooming and observed a rushed job from the groomer. Afterwards, we found cuts all over our pup’s armpit areas, her stomach area, and near her private area. A small nick here and there occasionally is normal sure, but this is not acceptable. We have never gotten our pup back in this condition before from any groomer and this was distressing to discover. Our pup does not struggle during her groomings so there is no reason she should be leaving the appointment with this many cuts unless it’s negligence and lack of care from the groomer’s end. Not only was our instructions not followed for the groom, but she came back injured. Not acceptable and would not recommend anyone to schedule an appointment with Alyssa N
April 26 · AlixExcellent Vet/techs!We are sooooo happy with Vetco on las Posas in San Marcos!!!Dr Massey and team are the BEST!*This is a huge “shout out” for Courtney (tech)!I brought Leo in for exam and he was calm, environment is friendly and welcoming.Courtney is so friendly, helpful and happy! She loves her “job” and it shows.Vetco and all the animals that come in are so lucky to have her! She is a gem!We couldn’t be happier with our Vetco and will never leave!
August 07 · Jill MerrittI am extremely dissatisfied with the recent handling of my dog’s grooming appointment. She was scheduled for grooming today, but it appears the appointment was rescheduled without any prior notification. Originally, her appointment was three days ago, but it was moved due to overbooking which I understand that it happens, and I have now been informed that it has been delayed again due to overbooking. This is particularly inconvenient as I took the day off work to bring her in. This ongoing issue reflects poorly on their scheduling and communication processes, and I would appreciate a clear explanation. If I can give a no star I would.
