Slow-Kill And Fast-Kill Heartworm Treatment

A bold divide exists among veterinarians on the topic of how to rid dogs’ bodies of heartworms. Few lack passion for this subject. “Slow kill” or “fast kill?” Traditional “fast kill” heartworm treatment which, by the way, is not particularly fast, involves the use of Immiticide. Two regimens are described in the drug manufacturer’s package […]

Activity Restriction Needed During Heartworm Treatment

Activity restriction is important for dogs undergoing heartworm (Dirofilaria immitis) treatment. However, it is not usually needed for the entire process, just during the time after Immiticide injections are administered.

When Immiticide […]

Heartworm Disease IS A Big Deal!

“My previous veterinarian didn’t act like heartworms were any big deal, that’s why Sharkie wasn’t on a heartworm preventive.

They are not every six weeks medications! Periodically, then, they question comes up, “Should I adjust my heartworm preventive administration for February?” No. If you normally give your heartworm […]

Veterinarians As Educators

There is no more important role of your veterinarian than that of educator.   Yes, we can fix things, and yes, when there is an emergency we have to remember our ABCs: Airway, Breathing, Cardiopulmonary. After the dust settles and the feathers are no longer flying, it is crucial that we sit down with clients […]

Questions About Heartworm Complications

Reader “SJaffe” writes to us, “Hi, Dr. Randolph, I foster a Cocker spaniel who is 12 years old. She is heartworm-positive and it’s just breaking my heart. I would love to do everything I possibly can do help her get through this. She doesn’t really have a cough but she breathes very, very deeply (with […]

Tale Of A Dog With No Heartworms

How does such a thing happen? This little dog came to me Monday, having never seen a veterinarian in her life. And she’s 10 years old. And her fecal flotation is negative for intestinal parasites. And her heartworm test is negative. It seems so amazing as to be impossible, but it’s true. Granted, she will […]
