I lost my 14 year old dog late last year and I still miss him every day. That said, no way am I getting another dog!
They are a lot of commitment. My dog was a really good puppy and not destructive, he even had some of his puppy plushies still when he died. He didn't chew on anything he wasn't allowed to, either.
We had our routine - I would get up early and we would go for a walk/run prior to me getting ready for work. I feel it's disingenuous for people to say it's cruel to leave a dog at home while you go to work - my boy was just fine, hanging out with my cats for company. I probably wouldn't leave a dog entirely on its own, but he was was great with the cats and there was 'mutual adoration'. I took him to puppy day care when he was old enough and he spent the whole day shivering and drooling in the corner, until the day care owner was forced to cuddle him all day, away from the other dogs. We tried several times, but he hated it and was much happier at home with his kitty mates. I also gave a key to my next door neighbour (who worked from home) in case he ever started barking or crying. He never did.
After work, I'd take him to a park for a run and a sniff. Maybe half an hour, or more in summer. We'd also do clicker training during part of that time.
As he got older, he slept almost as much as the cats. Which, if you know cats, is most of the day. I used to use puzzle toys and pack them with treats and leave them for him when I went to work. I read as much as I could on puppy and dog behaviour, including how to come and go from my home in a way that wouldn't encourage separation anxiety. That seemed to work well.
However, I found myself saying no to a lot of social outings because I wanted to give time to him. I didn't begrudge this at all - he was my little mate and I loved him to death. It was also really difficult to go away, even for a night. I would never leave him overnight - a few hours is fine, but not the whole night. I was lucky enough to be able to take him with me to stay at friends places a lot of the time, so it wasn't always hard. But, yes, they do curtail your freedom a bit.
And then there's the general cleaning (house and them), grooming if it's a breed that needs it regularly (mine did), and the loads of time you need to put into training them throughout their life.
All in all, they're a huge commitment, but they give back tenfold. I'm grateful that I grew up with cats and dogs as pets, but I got the shock of my life when I got my own dog because I had NO idea how much work they are! I remember asking my Mum (who was the one who cared for our family dogs) if my boy was 'normal' and she laughed and said "yes, having a puppy is like having a child". I had no idea - as a cat owner, I'd expected dogs to look after themselves in a similar way - nope, dogs are COMPLETELY dependent on their owners.
As I said at the beginning of this rather long post, I still miss my darling boy every single day. I even still shed the occasional tear, even after him being gone 14 months. He was a good and loyal friend. But no way am I getting another dog at this point in my life - I went and got another two kittens instead! 😁
