My younger brother (I have four brothers, two older and two younger) and his family got a dog a couple of years ago and one of my parents regularly walks a friend's dog and I often see that one too
Both nice dogs and I like to indulge them for an hour or two (and am usually interested in other people's dogs if they are well behaved and not a stupid breed), but the thought of owning either or them or any other dog terrifies me, especially because of the low IQ toddler aspect and everything else
My youngest brother and his partner also have a dog, but not much for longer and they won't be getting another one when it dies because they want to have a dog-free life
My nephew (younger brother's son) doesn't like dogs at all, but his partner either has or used to have one (would be / would have been a family dog) and would like to get another; watching them try to work this difference of opinion out is funny
I'm definitely a cat person, although I couldn't cope with the expense of owning one
