I just had this very convo with my vet on Friday . I have used nexguard on my little Spicey since I got her ,almost 2 yrs ago. Due to my sweet Sugar being diabetic I couldnt use it on her so I used frontline. When cancer took my Sugar last week I had 2 vials of Frontline left , the vet told me to go ahead and use them on Spice . I asked if I should use the whole vial and she said yes yes yes. BUT my Spice does weigh 7 lbs. |
