Prescription Pet Food in Far North Central San Antonio, From Your Local Vet

Petfolk Veterinary & Urgent Care - Far North Central is a vet in San Antonio, TX, that prescribes therapeutic diets for dogs and cats. A prescription food is part of the treatment plan, chosen after an exam, for problems like an upset stomach, food allergies, bladder stones or recovery after illness.

These foods are made to a medical recipe. They aren't sold off the shelf, because the wrong diet can do more harm than good.

What is prescription pet food?

A prescription diet is changed on purpose to help one problem. One may be extra easy to digest. Another may use a protein your pet has never eaten, or have less of the minerals that form urine crystals. The vet picks the diet, the amount and how long to feed it, then checks whether it's working.

At the visit, bring your pet's current food bag or a photo of its label, plus any treats and chews. That shows the vet everything your pet eats in a day, which matters when choosing the next diet.

Which problems can a prescription diet help?

At Petfolk Far North Central, the vet may suggest a diet for:

• Vomiting or diarrhea, to rest the gut while it heals

• Food allergies, using a protein that won't trigger the itch

• Bladder crystals or stones, to change the urine

• Weight loss, with fewer calories and more fiber so pets feel full

• Recovery, when a sick pet needs calories in small, easy bites

Stomach trouble leads the list by far. Across Petfolk, 84% of the prescription diets we send home are gastrointestinal diets, and about 1 in 10 (11%) is a recovery diet (Oct 1, 2025 to Sep 30, 2026). For skin-related food trials, see allergy testing and treatment in Far North Central.

How do I switch my pet to a new food?

Unless the vet says to switch right away, mix the new food in slowly over about a week. Start with a little new food in the old, then add more each day. For a food trial, the new diet has to be the only thing your pet eats. That means no table scraps, flavored chews or treats from the neighbors. Write down any vomiting, loose stool or itching, and bring the notes to your recheck.

Fear Free handling is standard at every Petfolk clinic, and that includes weigh-ins. A pet on a weight-loss diet can hop on the scale for a treat and a quick check, without a full exam each time.

What does prescription food cost?

The cost depends on the diet, the bag or can size and how long your pet needs it. You'll get an estimate before any test or treatment. The final bill can differ if the plan changes during the visit. PetfolkCare membership starts at $199 a year.

Feeding outside in San Antonio

Fire ants are found across more than the eastern two-thirds of Texas, according to Texas A&M, and a food bowl on the patio draws them fast. Feed indoors when you can. Pick up canned food that hasn't been eaten within about an hour, and keep dry food sealed in a cool spot, not a hot garage.

Reordering and rechecks

Ask the team where to reorder before the bag runs low, so your pet doesn't go back to the old food for a few days. Some diets are short term, and others are for life. The vet will tell you which one your pet is on and when to come back.

When not eating becomes urgent

A pet that refuses even the new diet for more than a day needs to be seen. A cat that stops eating can get sick quickly. If your pet is vomiting over and over, has blood in the vomit, or has a swollen, painful belly, go to a 24-hour hospital such as BluePearl Pet Hospital Stone Oak. For milder stomach trouble, see vomiting and diarrhea treatment in Far North Central.
