A VETERINARIAN has warned that pet owners who stop treating their dogs for heartworm in the cooler months are putting their pooches at risk.

“Many pet owners stop their pet’s heartworm preventative in the cooler months thinking that their pet is safe, but they are putting them at risk of the deadly disease,” he said.

“Mosquitos are responsible for spreading heartworm disease. While they are more prevalent in warm weather, dogs can get infected at any time of the year.

“Dogs have a special place in our hearts so it’s important we take care of theirs.”

Dr Perissinotto said heartworm disease could be avoided with the administration of a once-a-month heartworm preventative.

Adult dogs must be tested for heartworm before starting medication.

Puppies younger than four months can begin treatment without first being tested.

“Prevention of heartworm disease is one of the most important aspects of health care for your dog,” Dr Perissinotto said.

Symptoms of heartworm include coughing, weight loss, decreased activity and occasionally sudden collapse.
