I mean in both cases it must be possible for active ingredients to transfer from the dog to water, but in really tiny amounts. And spot ons being the dangerous ones for aquatic life because the product is applied in one big lump.
Thank you, that's really helpful. That's what I thought, logically, too. I'll check it with the vet as we get closer to the dreaded Tick Time...
Just wanted to point out that the German Office for Consumer Protection has issued the following statement about Bravecto: http://www.bvl.bund.de/DE/05_Tierarzneimittel/05_Fachmeldungen/2017/2017_01_24_Fa_Bravecto.html Basically, they are advising vets to discuss the use of Bravecto carefully with their patients, and to advise them of possible side effects, especially in possibly risk cases (such as dogs who have already suffered epileptic fits).
I've never worried about ticks but it looks like paralysis ticks are making their way to Melbourne. The vet hasn't advised prevention yet as there have only been a couple of cases but I guess it's only matter of time. Those things scare the out of me.
Labradors are the most reported big breed for adverse effects after taking Bravecto. (I think it was Toy Poms that are the most reported for adverse effects in small breeds.)
The was a big story about bravecto in dogs today mag this month. I bought it to find out a bit more. I don't think I will be using it
