Heartworm Prevention

Courtesy of American Heartworm Society

Most dangerous thanksgiving food for your pet:

6. Unbaked Yeast Bread Dough: Your dog’s stomach acts like an artificial oven, making the yeast rise and release carbon dioxide, causing a distended abdomen and potential life-threatening gastric dilatation-volvulus (GDV). Next, the yeast and sugar in the unbaked dough are metabolized to alcohol, which can result in secondary alcohol poisoning in your dog

​7. Alcohol: Accidental ingestion can cause severe coma, slowed respiration, and a life-threateningly low blood sugar in your dog.​

We currently carry the following heartworm prevention at our facility

1. Grapes & Raisins: Can result in severe acute kidney injury.
2. Xylitol (Found in Baking Goods): When ingested by dogs, it can result in a massive insulin spike, causing a life-threatening hypoglycemia (low blood sugar) and even liver failure with higher doses.

3. Fatty Table Scraps (gravy, turkey skin, etc): Potentially dangerous to your dog, as they can result in severe pancreatitis.

4. Bones & Turkey Legs: Risk for a possible foreign body obstruction. The bones can also get stuck in the stomach or intestines, potentially resulting in a perforation (or rupture) of the intestines.

5. Onions, Leeks, Chives and Garlic:Can result in oxidative damage to the red blood cells, making these cells more likely to rupture (e.g., hemolyze). Cats are especially sensitive, and can develop a severe anemia (low red blood cell count) from even small amounts. This is typically seen more with chronic ingestion (e.g., when they are eating it for days), but to be safe, keep these out of reach.


If you are missing or found a dog/cat here are some tips on what to do.


All dogs should be tested annually for heartworm infection to ensure that the protective program is working. A dog can become infected if just one dose is missed, given late, or spit out and can rub or swim off a topical preventive.

Every pet whether indoor or outdoor should 

receive heartworm preventive 12 months a year.

Both dogs and cats can contract heartworm but there is ONLY treatment for dogs.

Treatment for canine heartworm disease is expensive as well as traumatic and risky for the dog. The outcome is unpredictable, and treatment:
• Lasts for 4-6 months.
• Requires multiple injections of an arsenic-based
• Requires that the owner crate and isolate the
pet for 6-8 weeks.
• Involves significant cost—up to $1,000 or more.
