Right. I've been paying £20 every three months for Milebax. I paid this as I believed it prevented lungworms.
I've been told it doesn't, that he can still get lungworms.
Now I live in the SE, and previous Lab never caught lungworms and was on Milebax.
I also wonder about the effectiveness of Milebax on Hully as she ALWAYS voms the next day 
So
Can I now save myself £15 and use Drontal or similar? Or at least find a non vomity one?
Or is Milebax worth £20 friffing pounds?
