I have an 80lbs, 7.5 year old, male, Lab/St. Bernard/Australian Shepherd mix that I need occasional pet sitting for. I usually travel 1x/month and could be gone for up to 10 days at a time. He's a pretty low-maintenance dog that does well with being alone for long periods (up to 12 hours).
Feeding: 2x/day, breakfast and dinner (not particular about feeding times)
Regular schedule: doggy daycare 2 days/week; home alone from 730am-630pm, 3 days/week
Demeanor: he loves smell-filled walks, but if not walked gets spurts of playful energy. He typically does well with other dogs and goes to doggy daycare 2x/week but can be selective with what dogs he tolerates. Will sometimes pull towards other dogs on walks. Will sometimes randomly hump people. Very treat- and food-motivated. Not aggressive towards kids but doesn't know his size so can easily knock them down (see also: randomly humps people).
Medications: 1 joint supplement/day w/ breakfast
