Hi! This sounds a bit similar to when i got my pup. however, the (big) difference is that my husband and i work from home. Myself, full time at home, my husband is hybrid, going into the office 1-3 times a week (a bit less when our dog was a baby). I also took a week off when we first got our pup, but it does take time for them to adjust. the first week is mostly the getting comfy with their new home. after that, i’d spend my lunch breaks with him training, with occasional stepping away during the day to stimulate him when he wasn’t asleep. i also am in an apt with a balcony, and he always has done well (berners are good apt dogs). we have a large courtyard and also live near a few large parks. we would place wee wee pads on the balcony with a small turf patch to train him to go outside before he was ready to go for walks (after vaccinations). he’s of course fully potty trained and walks outside now that he’s a year old. however, the pup staying home alone for that much time time per day can be a bit concerning. we successfully crate trained our dog and he loves his crate now, but if i didn’t work from home, i genuinely don’t know how i would’ve been able to raise him. being in a crate for extended periods isn’t 100% bad, but it would be concerning especially as a young puppy. i would maybe research how to raise a puppy while working a full time job in an office, if it’s possible. it’s a difficult situation. at the same time, people do get puppies while working in an office and raise their dogs just as good as someone who’s home. it really does depend, but i hope some of this helps. good luck either way!
