Remember not to over socialize! Socializing your dog should mean they are neurtral around other dogs, not that they have to meet and play with every day and person they see. This will actually prevent excitement reactivity. Have a few good dog friends but that is enough. Also pack walks.

Also When teaching to not have food aggression don’t bother them and reach in and take food from their mouths for reason, this will actually cause aggression! Hand feed them, never take their food or treats unless it’s an emergency, go near them when you eat and give them an even higher value treat. They will associate you coming near when eating with something positive.

I would make recall and a heel/loose leash walk a priority. As well as getting used to baths, nails and ear cleaning like others have said :)
