Transitioning from Small Breeds to a Larger Breed

After over 12 years with two small boy dogs (a Dachshund/Pom mix and a Dachshund/Maltese/Yorkie mix), we just adopted a 4-month-old mystery puppy who looks like she could be a Chinook (which seems crazy given how rare they seem to be), so we’re eagerly awaiting her DNA results.

She’s already a very different experience from our previous dogs, and it’s dawning on me that raising a larger breed comes with its own set of considerations. For example, I’ve learned that larger breeds need to wait longer before engaging in high-impact activities due to growth plate concerns, which was new to me.

We’re planning to crate train and use clicker training like we did with our previous dogs, but I’d love to hear from folks who’ve raised both small and large breeds. What differences should we be aware of in terms of training, socialization, exercise, or general care? She’s still waiting on her final DHPP dose before we can socialize her, and she was spayed when we got her. It’s been over a decade since we’ve had a puppy this young, and we've never had a girl dog or a non-small breed, so I’m all ears for tips, insights, and things you wish you’d known when transitioning between sizes of dogs. Thanks in advance!
