That's something I remarked the moment I saw them for the first time, and as someone who also likes to hunt completely solo from time to time, at the moment it really does seem that dogs are absolutely mandatory. There's the 'wait' option, and at first I had hoped it might be the solution, but it's not good enough unfortunately. Once you call for transportation, waiting is disabled and you have to activate it again when you reach your target, which might be just a small nuisance, but the bigger issue is that the monsters don't ignore your waiting pets. Rather they start wailing on poor sitting, defenseless dogs and cats. So there's no solo experience at all anymore if you want quick movement on the map, which is a bummer.
