UPDATE - I gave up on Frontline and Tikva had her first Bravetco chewable tablet on 28 June. No itching, no scratching since, no sign of fleas and none of the possible c/i that might occur. Ram said that were she have a reaction, Heaven Forfend, it would have show up by now. All being well, no fleas/ticks/itching/scratching and more important, no nasty contra-indications, I will stay with Bravetco. The minor problem is that Ram has to give her the Parkworm shot every three months, and Bravetco is one chew every 12 weeks but he reckons to give the Bravetco at the same time as the Parkworm shot should be OK as it will only be a couple of days over the 12 weeks. Incidentally, the website Vee @GsdSlave gave me in message #2 is not so much warning about Bravetco and other oral anti flea/ticks, but a website selling their own products, including a "certificate" to become a Certified Raw Food Nutrition Specialist. Talk about a snake oil website.
