Having just got our Labrador pup and been told that he requires worming every 2 weeks I started to look into what was best and frequency online - What do you recommend? He was done after we got him with Milbemax - but I don't think i'll use that again due to remarks on this forum about it! although I have to say he showed no reaction this time it was flipping expensive from our vets! according to the 2 week rule he is due again this friday but further to reading about others; if these drugs are upsetting their stomachs are we pumping too many chemicals into them? yes we want to keep worms away but is there not a gentle longer lasting one? I also have horses so understand the importance of keeping them regularly wormed but what is best? I would especially like to hear from equestrian people as I am sure all dogs and horse poo have the same attraction! Monty is currently coming up 10 weeks. Thanks :)
