Daily Updates

We understand the anxiety that comes with having a hospitalized pet. That is why our technicians are able to provide the most complete information as to your pet’s condition. These updates are regularly given after 10 a.m. to allow time for the doctors to evaluate your pet’s progress and review their labwork. Please know that the Animal Emergency Clinic located in the same facility as GCVS is unable to provide updates on our patients.

We can also be reached at medicine@gcvs.com and offer the option of brief updates via text message. Please notify your technician if you are interested in either of these options.


We know and understand how difficult it is to leave your pet. If your pet has been hospitalized, you are welcome to call ahead and schedule a visit. If your pet is stable enough to leave the ICU, a 30 minute family visit will be provided. A brief 10-minute visitation is allowed for those patients in critical condition. Family visits may be scheduled during the following times:

  • Monday-Friday 10 a.m. – 6 p.m.
  • Saturday 10 a.m. – 2 p.m.
  • Sunday No Visitations (*Special arrangements may be made for critically ill patients)

Client Information

  • How do I care for a pet with a nasogastric tube?

    The Nasogastric tube (NG tube) is a feeding tube placed through the patients nose which runs into their stomach.

    Even though you are supporting your pet with NG tube feedings, the ultimate goal is to have your pet regain his/her normal appetite and eat on his/her own.  This can be accomplished by continuing to offer your pet a variety of foods prior to NG tube feedings.

    As your pet begins to eat on his/her own, decrease the feeding volumes accordingly.  Taper down the amount administered using your best judgment to determine how much to feed through the NG tube.

    Feeding: First aspirate (draw back with an empty syringe attached to the tube) the NG tube.  If you draw back 40 mls skip the next feedings.  Always feed the diet at room temperature or slightly warmer.  NEVER microwave the food.  Test the temperature on your wrist to be sure that it is not too hot or too cold.  Always inject the gruel through the NG tube slowly over 10-15 minutes to decrease incidence of vomiting.  Some pets require longer, slower feedings to avoid vomiting.  The minimal amount of time between feedings is 3 ½ – 4 hours.

    Flushing: always flush the tube after feeding or giving medications to avoid clogging.  Slowly flush the tube with 5-10 cc of warm water.  If you find that the tube is clogged, you can flush 2-3 mls of Coca-Cola® down the tube to dislodge any obstruction.

    Medications can be given through the NG tube as well.  Pills can be crushed and put through the tube dissolved in water.  Always flush the tube with water (5 cc) after giving medications.  DO NOT CRUSH CHEMOTHERAPY MEDICATIONS.

    If your pet vomits, skip the next feeding.  When the next feeding is due, give the food slowly and watch your pet carefully for vomiting or signs of nausea (i.e. salivating, licking lips, etc).  You may need to administer the food more slowly or decrease the amount given per feeding.  If your pet vomits more than once daily, consult your veterinarian.

    You will need to inspect the site where the NG tube enters the nose to make sure the tube is still attached.

    The NG tube should be capped at all times when not being used.

    Consult your veterinarian if your pet deteriorates, or if you have any further questions or concerns.

  • What are the dangers of sago palms?

    Sago palms (also called King palms or King Sago palms) are a hardy, ornamental plant found commonly in the Houston area.

    Given their prevalence, you or someone near you may even have one of these Sago palms growing in the yard.  But did you know that this plant can be harmful to your pets?  Dogs in particular are likely to chew on these palms or ingest the seeds/nuts and may become extremely ill as a result.  While it is not well understood why these plants are so toxic, we do know that they primarily affect the liver and can lead to liver failure and death.

    If your dog has access to these plants, please be sure they are supervised when around them.  If your dog does eat or chew on the bark or seeds of a Sago palm, please seek veterinary care immediately.  The sooner the exposure is handled, the less likely the risk of long term complications.
