If you live in an apartment, just don’t get one
Reasoning edit: pets, especially cats, will leave a smell all over furniture. Cleaning becomes an even worse chore due to the fur. They also require “house training” in order to not chew/claw/destroy most stuff that’s lying around the house.
Of course a dog should be activated physically and have attention, but it’d also be cruelty to keep it awake and active all day long.
Dogs sleep a lot. They need 12-14 hours every day, and even up to 20 hours for puppies or old dogs.
This fits very well with being left unattended while the kids are at school for instance.
It’s better to leave it unattended for one long stretch than several shorter ones daily, because dogs do keep track of time based on routines. Coming in and out several times, or taking the dog along randomly is more stressful for it, because it breaks the routine.
They’re very adaptable and teachable, so many things are possible, but it should definitely be taught to chill out by itself, so it’s capable of this when you actually need it to be alone for some reason.
