Google Bravecto – I wouldn’t give it my dog.
This is going back circa 5 nearly 6 years, we were new to being dog guardians and had 100% blind faith in our (1st vets). We tried spot on but it damaged our dogs fur at the application point, asked the vets advice they recommended Bravecto. I paid for it but then noticed Bravecto branded advertising in the vets which raised my suspicions. Came home googled it and threw the Bravecto in the bin. Changed vets shortly after. Haven’t used any flea treatment since.
I’m going to summerise but it makes the dog toxic enough that fleas and ticks cannot survive on the dog. There was enough information out there (at the time) for me to not give it my dog. Vets are commercial enterprise’s who balance profit against what’s actually right for animal care, some lean more than others.
I don’t regularly wash our dog (probably once a year), his fur has lots of oil. He gets brushed a lot, he’s never had fleas and has been to doggo day care plenty of times.
