So i think i made my mind up!!! I am not going to wait until my little one is 3lbs (he is 5months) to take Advantage plus that our vet gave us. I am going to switch both of my little dudes to Interceptor and POSSIBLY K9 Advantix (instead of Frontline, that we currently use)
Good choices?!!!???

I was using heartgard plus but agree, i wont anymore because of the huge weight difference (1-25lbs) wow!
The only issue I am struggling with is the K9 Advantix, my vet said they do not recommend it because it uses some old ing. that isnt used anymore??? Does anyone use this or have heard about that?
This stuff is so confusing!!!
