Yes, critical issue during the day, they will get you in immediately. It is why I am back with that vet.
The story played out a bit on here, and I got some great advice at the time, but a recap: Not long after I got Gusto, I left the vet I had used for a long time strictly over prices. I had zero complaints about their services or care, but Gusto needed to be neutered and Meg needed her teeth done, and they were quoting nearly twice what any other clinic was. I simply couldn't afford it. I tried to get in with a vet several friends use, but the best I could do was another vet in the practice she owns.
When I got a call at work at 3:00 pm that my mother had gotten home, there was vomit and poop all over, and Gusto couldn't walk, I told her to go straight to the vet and I would meet her there. I called them as I was walking out of work and they said "we can get you in at 3:45". I said "No, this is critical, and the dog is on the way." I tried to call my mother back to tell her to go to the emergency clinic (which I had never used, and doesn't officially open until 5 pm but is staffed 24/7) but she had left already. She got him to the vet by 3:15, I was there by 3:20, we were seen at 3:35. For a dog who was basically non-responsive, couldn't stand, swallow, or see. They did send us to the emergency clinic, where we were treated fantastically.
When we went back for bloodwork the next week, I brought up my concern over how long it took to be seen, and the vet basically brushed it off as "well, you could always just drive to the emergency clinic". I was so upset by how blase he was about it that I just moved back to the other vet. I can find the money to pay their prices for the reassurance of a vet who will see them right away (and not argue with me about vaccines, and honor my request to not take my dogs in the back for blood draws).
