Frontline question on weight

[Darcy & Millie]

I bought a 3-pack of puppy frontline when Millie was very small, and now she's over the weight that it goes up to.  I believe it goes to 22 pounds, and Millie's 32 pounds.  Could I give her a double-dose of it, or is that not safe?  I can call my vet tomorrow and ask, but thought I would ask here first, as we're overdo by a few days..grr..

Thank you!

If you are using Frontline Plus the up to 22 lbs contains .67 ml

the 23 to 43 lbs contains 1.34 ml (exactly double).  So applying 2 of the up to 22 lbs is the same as applying 1 of the 23 to 43 lbs.

 

(see below)

Frontline Plus for Dogs & Puppies 8 weeks or older and up to 22lbs:

Active ingredients (per 0.67 ml applicator)	Amount
Fipronil	9.8%
(S)-methoprene	8.8%

Frontline Plus for Dogs 23-44 lbs:

Active ingredients (per 1.34 ml applicator)	Amount
Fipronil	9.8%
(S)-methoprene	8.8%

Frontline Plus for Dogs 45-88 lbs:

Active ingredients (per 2.68 ml applicator)	Amount
Fipronil	9.8%
(S)-methoprene	8.8%

Yes, I agree. Just use up the smaller doses two at a time.

Thank you to both of you, glad I didn't have to waste any!
