I keep all of mine on Advantix so no fleas or ticks.My last dog was a Doberman. Very smart, and very easy to groom. Didn't get fleas so no flea treatments necessary! She hunted moles.
Two of my past Dobermans, the black male (Dylan) in my avvy being one, were pet therapy certified. I could let Dylan loose in a daycare and he'd have been in his glory. He absolutely adored children. He'd let them climb all over him and play as rough as they wanted. He loved it.
