Molly's ears are bothering her and they is a bit of brown smelly wax in them. She had ear mites as a tiny puppy which were treated and the vet recommended Stronghold flea treatment which was supposed to also prevent ear mites, some types of worms and mange.
I know it might not be ear mites (and I will be taking her to the vets to find out) but does anybody know how effective Stronghold is?
