Hi my mum has a dog who is also allergic to flea saliva,
Hes a beardie so if he likes a chews its it get mankier.
Hes flead regular yet one flea bite and hes raw!
To help it we use (in a spray bottle) Tree tree, Witch hazel and salt water (home made), shaken and applyed 3 times daily (or more). it really works and you should try it,
