I am use advocate on saxon for flees and have never had a problem.
Soon i will be moving to a high tick area and i have the preventic collar but the only problem i have is that when i am at work saxon will be in the yard, and i worry that if it rains and he does love running around in it, i will have to constantly change them.
Does anyone know if you can use advocate and proban together. Atleast then i know he is being protected when i give him the tablets.
