Cardiology Services for Pets

Our veterinary team believes in preventive healthcare to ensure your pet doesn’t develop any heart issues. An example of this is prescribing a monthly parasite control medication. If your pet has developed a heart issue, our team of experts is here to support your pet by giving them the compassionate and required care they need.

Are heart issues preventable in pets?

Some pets are born with heart conditions (congenital), while others develop them over time (acquired). For congenital conditions, your pet might be predisposed due to their breed or have had the condition passed down to them through their lineage. Acquired conditions on the other hand, can be caused by aging or general wear and tear your pet experiences as they get older. Other factors like obesity can also increase the risk of your pet developing a heart condition.

How can parasite preventives protect my pet’s heart?

Heartworms can cause heart disease. If your pet is bitten by an infected mosquito, heartworms can enter your pet’s bloodstream. Once inside your pet’s body, they can move to your pet’s lungs and heart, growing to be a few inches. Pets can be infected with anywhere from 1 to 100 worms at a time, causing heart and lung disease overtime. Thankfully, your pet is protected against these parasites if they’re taking a preventive medication as prescribed. If your pet doesn’t have a parasite control plan, please contact our veterinary team to discuss which ones might be the best fit at 416.941.8920.
