Advice for a first time owner who wants a Shepsky

Hey, I am just looking for advice on how I can get ready for owning a Shepsky.

I have 2 kids I have 50/50 with their mum, I work from home with 1-2 days in the office. I have a big long house with a long garden which would be perfect for a dog to run around. And I have a lot of good parks and long walks nearby.

I want a Shepsky because they seem to be complimentary breeds they are family orientated from the German shepherd and playful from the husky. They also seem to negate some of the negatives from both breeds where they are less if an escape artist but also not as reactive.

I'm aware that cross breeds aren't always predictable but from what I have read they seem to fit what I want. I am also aware of their high exercise needs and have watched lots of videos about training a working dog. I am wanting to have a dog that needs lots of exercise because I am into fitness and want to do more of it, perhaps running with the dog using one of those leads that go around your waist.

I'm asking how will I know if I'm ready and I'm not willing to find out the hard way that I'm not a ruin a perfectly good dog. I read that both Huskies and German Shepherds are not good dogs for first time owners. But I'm 38 now, by the time I'm not a first time owner I'll be over 50 since I don't really think I have time for 2 dogs in the next few years.

So in summary, I feel like I have read enough to know this is the right dog breed for me and the lifestyle I want. But how is there anything I should be doing to make sure I am ready to take this dog on as a first time owner?
