Like having a child, you need to understand the full responsibility a dog is. Although I’ve grown up with family dogs, I’ve always known that when I grow up, I wanted to be the primary dog mom. What I did not realize until I was the full time caregiver was the 24/7 responsibility. This is not to say you need to be beside your dog and physically attached for 24 hours a day (since they sleep 60% of the day anyways), but you need to have a plan to account for how they spend the full day.
When you go to work, where will the dog be? Day care? At home? In a crate?
When you go on vacation, where will the dog be? Day care? Friend’s house?
As a rule of thumb, when your dog is under 6 months old, do not leave the dog for more than 4 hours. More than this and you put your dog in danger. We pushed the limits and left our dog for 6 hours alone one day, and luckily nothing bad happened, but he was not happy at all.
Another increasingly popular option is installing a nest camera. As a worry worm, this came in handy so that I didn’t have to constantly wonder what my pup was up to.
