From docsef’s desk- Parasite Prevention

Mayday. Mayday. Parasite Prevention is needed because heartworms, ticks, and fleas are headed our way!

I feel like in my last few blogs and now with this one, I am beating a dead horse.

However, the first sentence above really is true. Heartworms, ticks, and fleas are heading our way. No, they actually are already here.

Just this week:

  • I have diagnosed a dog with heartworms who has been on heartworm prevention for the last 10 months but was probably exposed prior to taking the prevention.
  • I have seen a dog infested with ticks who was not on tick prevention.  And I have had other owners tell me they have found ticks on their dog.
  • I have treated several cases of Flea Allergic Dermatitis that only results from a flea infestation.
  • Heck, I found a tick on myself this past weekend!

And these cases are just mine. Compound that with my colleagues within our practice, or my colleagues within Cabarrus County, or even my colleagues in the Charlotte region and the numbers will grow exponentially. And all the while, this doesn’t even include pets that haven’t been to a vet this spring!

So here are my recommendations:

  1. Have your dog tested for heartworms every year. Do this even if he is on heartworm prevention. (see the first bullet point above)
  2. Keep your dog and cat on heartworm prevention year-round. Please understand- there is not enough cold weather in Cabarrus County/Charlotte region to kill the mosquitoes (that spread heartworms) and other pests to warrant not protecting year-round. And understand that heartworm prevention also prevents intestinal parasites that also are unfazed by our mild winter temperatures.
  3. Stay on tick and flea prevention year-round! (see point two above about our so-called winters)
  4. Use products that have great safety data, are newer generation, and are proven to work. Need some suggestions? Here you go:
