Hi - just wondered if flea and tick treatment on re-entry into the UK would effect the chances of conception?

Thanks in advance.

Wouldn't think so my girl had 8 pups (though we lost one) in 2006.  I am hoping to take her daughter abroad for mating weather permitting, and will of course need to treat her before our return.

The fertilised eggs are independent of the bitch until after implantation around three weeks.

Thanks for your reply Brainless
