"He has a dog and six cats."
Translation:Hij heeft een hond en zes katten.
'Hij' is always 'hij'. There is no unstressed equivalent like there is with 'jij', 'zij' en 'wij' :)
Well the extra laziness is that it get stuck onto the previous word. ..
(I guess because the conjugation of he with regular verbs always end in t and that works nice with the ie. It also works well with the s from unregular is )
