My dog is due his Frontline flea treatment on Friday 7th August

Resolved Question:

My dog is due his Frontline flea treatment on Friday 7th August but has a flea that is making his life a misery with bites on his legs and around the tail. Would it be ok to give him treatment a few days early please?

Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.

In regards ***** ***** Gus now, that is absolutely fine. We can even use these every 2 weeks when needed. That said, if you have found the Frontline to be less effective as of late, I would warn that we are seeing increasing flea resistance to it these days. Therefore, you may want to instead consider using an alternative treatment (ie Advocate, Activyl, Vectra-3D, Advantage II or Advantix) at this point to protect him from fleas.

Finally, if Gus is chewing himself raw with this, I would note that you can reduce his itchiness (since it is a flea allergy dermatitis that often makes them bite/scratch) by treating him with OTC Piriton (chlorphenamine). Generally speaking, we can treat dogs with 4 mg every 8 hours or as needed to just soothe the allergic irritation the flea saliva causes. Of course, do be aware that this can make them a wee bit drowsy and do plan to check with his vet first if he has any health issues or is on any medication you didn't mention.

I hope this information is helpful.

If you need any additional information, do not hesitate to ask!

All the best,

Dr. B.

Hi Doctor B, that's fantastic news that I can apply the Frontline early. Gus normally responds well to it but I will try another make if this happens again. Can I buy the 'normal' OTC Piriton or do I have to get a dog-specific make please?

You are very welcome, Colleen.

If he responds well, then that is grand and we can use it now. In regards ***** ***** I was referring to human over the counter Piriton available at our chemists or grocery stores. There is no dog specific one, as the human one is safe to use for them.

All the best,
Dr. B.
