we have both a rotty terrier mix and a JRT. Our JRT is a cuddler, thinks hes a lap dog, and unlike what we have come to expect is quite laid back because we exercise him daily . He does like to play but after a time will sit up on his hind legs next to you with those sweet eyes pleading to be held. He lets the older rotty take the lead most times but when they play he stays right in there.
they both are great dogs ..great with kids...and adults..i would get both breeds again in an instant.
