I think your taking Jaxon to school to get him use to traveling in the car and going for a walk to the school is a great idea, and it gives you an opportunity to be seen with your boxer baby. I think it's also true that some adults and children are just plain afraid of dogs -- any dog, any size, any breed. For those children that aren't afraid, it's a great opportunity to socialize your dog and let others see how good Jaxon is with children. In the meantime, don't be offended that some people are standoffish, it's up to them when and if they want to warm up to a strange dog (even a puppy). You be positive and you will attractive positive and interesting people to you so you can tell them all about your lil guy.
