Clinic Policies


The CAP Vaccination Clinic does not provide treatment for sick, heartworm positive, or injured animals. Please see a full-service veterinary clinic for these issues.

Please stay inside your car.  When you arrive, please call the clinic at 281-600-8500 and we will come out to you.

To purchase heartworm medication, dogs must have been seen by our vet within the last year and be heartworm tested either:

  • at 6 months of age if not on prevention
  • at annual visit during 2nd rabies vaccination if on prevention since 2 months of age
  • at the annual visit as an adult



Your pet will receive a basic examination by the veterinarian which includes an examination of the skin, eyes, ears, mouth, teeth, temperature, and overall body. If minor health issues are detected, such as fleas or parasites, the veterinarian can suggest medication for treatment. If the issues are more serious, you will be instructed to take your pet to a veterinarian. In addition to vaccinations, the Wellness Clinic offers:

  • Heartworm test for dogs 6 months and older
  • Microchipping through 24Petwatch network
  • Nail Trimming
  • Preventative Heartworm/Flea & Tick Medication
