Worth noting that both above links are to Bayer websites & that Bayer have a significant footprint in the market of worming & flea prevention products.
I use currently use advocate flea treatment and wormer spot on (recommended monthly) plus droncit tape wormer (3 monthly), albeit mindful that some owner prefer to look into alternative products, holistic flea control options &/or service providers that analyse stool samples for worms.
Always worth reading articles, opinions as well as reading up on pro's/con's & of course product info & literature.
It should be noted that with advocate I believe that when administered the wormer aspect acts as if treating a dog to rid of worms whereas the flea aspect acts to control as well as treat these parasites.
I believe that Milbemax (not believed a bayer product) should not be given at same time as ( or within a certain period of) Advocate as the dog can allegedly be ovordosed. Also advantix (flea treatment only but combats lime disease found on deer & carrried by parasites) also made by bayer has an ingredient also found in the advocate. (a prior vet of mine did NOT know this)
Not going to make personal recommedations as I am very aware of the potential consequences of things going wrong re inadequate, imroper or even excessive protocols.
