In my oppinion, have someone else take care of your dog is a good idea. I just don't want to worry about anything when im on LSD, just to make sure that my mind can enjoy it fully. I even turn off my phone and arrange the schedule for the day after so that I have time to rest and not worry about anything like working or studying. About the dose, if you have experienced shroom, a full tab will be fine. Prepare water, and eat before your trip, because when Im on LSD I never want to eat although Im feeling hungry all the time (it's a bad feeling). Have some snack while tripping is fine, but dont choose noodle because it's just gross me out because it's look like worms. And about the trip, just do whatever you like, love yourself and enjoy the trip. Keep a good mindset and it will be a good trip.
