We have only wormed Ruby once (maybe twice) since we got her 3+ years ago. I have seen some threads recently in which people say they deworm a few times a year.... Wondering how important/necessary that is? I analyze every poop and have never seen any worms tho I know some can be in there and are not obviously visible.... We don't play with other dogs or really have that much 'exposure'. Neighbors have cats and one had tapes last year but I think they took care of it. Someone left a dead rat in the garage day before yesterday but it was not really chewed on (it had injuries but they looked more like a crow did it than one of my dogs)... (We do monthly heart guard but that's it)
Should this be done as a routine thing or only 'as needed' ?
