Petfolk Veterinary & Urgent Care - Far North Central is a vet in San Antonio, TX, with basic ultrasound on site for dogs and cats. The vet uses it during a visit to look inside the belly or chest, or to collect a clean urine sample, without surgery.

Ultrasound uses sound waves, not radiation. Most pets stay awake and relaxed for the scan.

What does the vet use ultrasound for?

At Petfolk Far North Central, basic ultrasound helps the vet:

• Collect urine straight from the bladder with a fine needle, so the sample is sterile

• Check the belly or chest for free fluid after a fall, a fight or sudden weakness

• Take a closer look at the bladder when a pet strains, pees often or has blood in the urine

• Decide the next step after the exam, blood work or x-rays raise a question

Across Petfolk, nearly three in four ultrasound procedures (73%) are this kind of guided urine collection, called cystocentesis. About 1 in 8 (12%) is a quick, focused scan of the belly or chest, often called a FAST scan (Oct 1, 2025 to Sep 30, 2026).

Why collect urine with ultrasound?

A sample caught in a cup or scooped from the litter box picks up bacteria on the way out. That can make a culture look like an infection when there isn't one. Guided collection takes a clean sample from the bladder itself, so the lab result is easier to trust and the vet can pick the right treatment. Most pets barely notice the needle.

What happens during the scan?

1. The vet explains what the scan should answer and how it fits with other tests.

2. You'll get an estimate before any test or treatment. The final bill can differ if the plan changes during the visit.

3. Your pet lies on the table, on the back or side. A small patch of fur may be clipped, and cool gel goes on the skin.

4. Focused scans and urine collection usually take just a few minutes.

Fear Free handling is standard at every Petfolk clinic. Team members support your pet gently, talk to them, and offer treats when the vet says it's safe. A pet who is too tense to lie still may need light sedation, and the vet will talk with you before giving any.

When a full ultrasound is the better choice

Basic ultrasound answers focused questions. Some problems, such as a mass on the liver or spleen or a stomach issue that keeps coming back, need a full scan of every organ by a specialist. If your pet needs that, the team at Petfolk Far North Central will explain why, help you find a specialty clinic, and send along the exam notes, lab work and x-rays.

How much does a pet ultrasound cost?

At Petfolk Far North Central, the cost depends on the type of scan and any lab tests run on the sample. Nothing is added without your OK. PetfolkCare membership starts at $199 a year, and CareCredit financing is accepted.

Before you come in

• Ask whether your pet should skip a meal. Some belly scans are clearer on an empty stomach.

• For a urine sample, try not to let your dog pee right before the visit. A full bladder makes collection quicker.

• Bring a list of the medicines and supplements your pet takes.

Urinary signs to take seriously

In a hot San Antonio summer, a pet that drinks and pees more is easy to blame on the weather. If it lasts more than a few days, have it checked. A male cat who strains in the litter box and makes little or no urine may be blocked, and he needs care within hours. If the clinic can't see him right away, take him to a 24-hour hospital such as BluePearl Pet Hospital Stone Oak, at 503 E Sonterra Blvd. For other worries, see sick pet visits in Far North Central.
