Agree Carrington. My Vet told me that most adult dogs will not have worms unless they have regular contact with young puppies and pregnant and nursing bitches.
If we concentrate on those an occasional worming is enough for adults.
As I no longer have a flea allergic dog I stopped using flea products routinely following a reaction to spot on after pet travel abroad. I had previously used the spray version with no problem as it's more dilute, and you use more f it all over.
I will use a household spay with insect growth inhibitor, and as mien are only occasionally bathed Vetzyme insecticidal shampoo.
Again never had fleas with the dogs, though when grass was long in back garden a litter of pups picked up some hedgehog ticks, Frontline spray on cotton wool and problem solved.
