Vomiting in Pets: What Does It Mean?

Monday, June 21st, 2010

Vomiting can have numerous causes
Here at Greenbrier Emergency Animal Hospital, vomiting is one of our most commonly presented complaints. “Doc, my pet is vomiting. What’s causing it, and what can we do about it?” are questions we hear on an almost nightly basis. Unfortunately, the answers are not always simple. Just like in people, vomiting can be caused by a variety of problems.

Sometimes, vomiting is caused by nothing more than inflammation of the stomach or intestines, resulting when your pet ingests something upsetting to the stomach. This kind of case can be treated supportively with subcutaneous fluids (injected under the skin), anti-nausea medication and antacid medication.

Other causes of vomiting include parasitic, bacterial and viral infections; congenital abnormalities (abnormalities patients are born with) and structural abnormalities, including structures in the gastrointestinal tract or masses that prevent food from passing through appropriately; ulcers; and food allergies.

Sometimes, vomiting is directly related to something your pet has eaten — and this kind of situation can be very serious! Some of the most common vomit-inducing toxins we see here at Greenbrier include antifreeze; rat poison (if it can kill rats, it can kill your pet!); drugs (including over-the-counter medications, herbal medications, medications prescribed to the owner, medications prescribed to the dog, and illicit drugs); household plants; cleaning supplies; grapes; raisins; onions; chocolate; and moldy food, which can also produce tremors, seizures and even death.

Occasionally, something your pet has eaten will create an obstruction, which in turn causes vomiting. Some common items that produce obstructions when eaten by pets include underwear; socks; towels; hair ties; string (which may be attached to buttons or a needle); ribbon, including balloon ribbon; tampons and other feminine hygiene products; baby bottle nipples; pacifiers; baby toys; fishing line; dental floss; holiday ornaments and tinsel; rocks; and dog or cat chew toys.

Vomiting can be caused by systemic problems as well, including fever, kidney and liver disease; inflammation of the pancreas (commonly called pancreatitis); vestibular disease; inner ear infections; and seizures. Uncontrolled diabetes, hyperthyroidism, and Addison’s disease can also cause vomiting. In older patients, cancer can cause vomiting. Even medications like antibiotics, chemotherapeutic drugs and anti-inflammatories can cause vomiting in some patients.

So my pet is vomiting — what should I do now?
First, stop feeding your pet. Second, make an appointment with your veterinarian or bring your pet into Greenbrier Emergency Animal Hospital right away. As the cause of the vomiting can be almost anything and a diagnosis usually cannot be made over the phone, you’ll need to seek medical treatment for your pet quickly. Discuss with your veterinarian what the vomit looks like, how much there is, how many times your pet has vomited, your pet’s energy level, and whether the vomit is associated with anything specific (e.g., right after your pet eats, right after running, after a seizure, etc.).

After a physical examination, your veterinarian or the doctors here at Greenbrier will make recommendations for diagnostics and treatment. Diagnostics often include fecal examination, blood work and radiographs. Sometimes patients will need gastroscopy (during which a camera is used to look inside the stomach).

Treatment for vomiting can include withholding food for a specific time period, keeping the pet on a bland diet, administering fluid therapy (subcutaneous or, in more serious cases, IV fluid therapy), antibiotics, oral medications, anti-nausea medications, antacids, and plasma transfusions. Occasionally — especially when a foreign object is involved — patients will require surgery.

If you see your pet eat something he/she is not supposed to, be sure to bring your pet to a veterinarian or Greenbrier Emergency Animal Hospital IMMEDIATELY. Quick treatment can often reduce or completely eliminate the problems caused by some of the most commonly ingested items.

Pets and Snake Bites: Act Quickly!

Friday, June 11th, 2010

As the weather warms, our slithery, venomous snake friends become more active. And snake bites are a very common problem in the summertime. Our pets are very curious creatures and tend to lead with their noses and their front limbs, so that’s where we see the most bites (on the face and front legs). These bites often cause extreme pain, swelling and bruising, and that’s typically what you as an owner will notice first, if you don’t happen to see the snake itself. You may also see puncture marks that may be bleeding or oozing.

What should you do if you suspect your pet has been bitten?
Bring him/her in immediately to your veterinarian or to Greenbrier Emergency Animal Hospital. Besides being extremely painful, snake bites can cause skin sloughing, shock, dangerously low blood pressure, bleeding abnormalities, and — in rare cases — death. Upon your pet’s arrival at the clinic, we will likely clean the wound; start medical therapy to make your pet feel more comfortable and maintain blood pressure; and perform diagnostics, including blood tests. Often, your pet will need to stay in the hospital for a short time, depending on the severity of the injury. Most snake bites in our area do not require anti-venom, however.

Although snake bites are very painful and can have very serious consequences, most pets do very well with prompt treatment — so if you suspect your pet has been bitten, act quickly to bring them in. Keep your pet as calm as possible. And if you see the snake, remember what it looked like, but DO NOT PICK IT UP! It can bite you, too!

Xylitol: Not So Sweet for Pets

Tuesday, June 1st, 2010

Xylitol, an increasingly ubiquitous sugar substitute, is found in sugarless gum (e.g., Orbit, Trident, Dentyne), sugarless candy, a granulated form for baking, and even in toothpaste. Xylitol has antibacterial properties in the mouth, thereby reducing bacterial load and periodontal disease. Preliminary studies have shown that xylitol may have other far-reaching benefits to humans as well, such as reducing osteoporosis, helping with endometriosis and fibroids, and helping to prevent ear and throat infections.

In dogs, the effects of xylitol are very different. A dog’s pancreas will recognize xylitol as sugar, causing the pancreas to secrete insulin, which in turn causes a profound drop in blood sugar — a dangerous condition that can eventually turn deadly. And it only takes a small amount of xylitol to cause clinical signs — for a 20-pound dog, ingesting just two pieces of gum containing xylitol can be toxic.

Initial clinical signs of xylitol toxicity are related to low blood sugar: lethargy, weakness, disorientation and collapse. Clinical signs of liver failure usually occur 12-24 hours after xylitol ingestion and can include diarrhea, vomiting, seizures, uncontrolled bleeding and death.

So what should you do if you suspect your dog has ingested xylitol? Although there is no specific antidote to xylitol, seek veterinary care immediately. Your veterinarian will likely induce vomiting and place your dog on IV fluids to increase its blood sugar. Blood work will also likely be performed to monitor liver enzymes, blood sugar and blood clotting times. The best chance for your dog’s survival after ingesting xylitol is to begin supportive care as quickly as possible. So if you suspect xylitol toxicity, don’t hestitate! Get your dog to your veterinarian or emergency animal hospital as quickly as possible.

As a side note, it remains unknown whether xylitol is toxic to cats. There have been some anecdotal reports of xylitol toxicity in ferrets, however.
