i recommend all travelers don't travel with a dog. that's just my personal opinion. most traveler kids suck shit at owning a dog. i've traveled with some cool kids with great dogs but they're been few and far between.
what are you getting the dog for? is it to alleviate loneliness? if so, that's a shitty reason to get a dog.
no one is ever happy by themselves all the time. but if one is never happy alone, that's a sign that maybe they have an issue or two that needs to be dealt with.
the reason people should have a pet is because they want to teach it and watch it grow. they want the deep and involving responsibility for another creatures life.
not because they are lonely, or they need something to yell at, or they want to shatter their alcohol bottles all over the ground only to have their dogs walk through it (i'm talkin to you oogles out there), or because other traveling kids have dogs, or because it's part of the travel kid uniform, or maybe they have absolutely nothing to say, social situations are painful because they don't know how to communicate, they get lonely, they get angry, they get sad, they get a dog.
Now all social interactions have a centeral figure (the dog) to focus on, turning down some of the pressure to be social, shifting the spot light away from unaddressed personal issues... ("huhuh my dog is so great ain't he? i can't talk about anything else but my uniform... oops did i say uniform? i mean dog").
i find myself in situations with animal owners and all they speak about is their animal. what the hell would they talk about if that poorly trained animal didn't exist?
