Good grief! Every year when Mississippi State University starts Fall classes - I hire some part time college kids to make formulas. Usually Science or Vet students since they have a real interest in what we do here. Unfortunately - these students brains - just like my brain - goes stupid on details. You can be assured that your Pet Wormer is what it is supposed to be - I make the Pet Wormer myself - but I grabbed the wrong insert.
I have even spent hours researching and making custom orders for folks and will forget to even put a regular dosing insert into the envelope. PLEASE accept the apologies of a "mad professor" :) I am still working on better labeling.
Just a little garlic powder in or on your dogs food is all he needs. Just a pinch. Too much of anything is not good - but a tiny amount is fine. The alicin in the garlic will cause his skin to be unattractive to biting insects. He won't smell bad to you or himself - but the biting insects can't stand it. I feed a little garlic powder to my dogs and they don't have fleas or ticks - and this is flea and tick country.
