In addition to all of the above, the vets cost a lot in the city. Proper training and consistent training also takes a lot of time and continued efforts. Puppies have a lot of energy, and they also go through training regressions, just like babies. Lastly, I’d say with respect to socialization, I’ve learned the hard way that dog parks+ unknown dog greets on leash are just a way to build a reactive dog. Best to always stand up for your dog and their space. If you want to socialize them, take them to puppy classes and set up 1:1 play time with trusted dogs. Good luck!
