While it's a bit of a stretch that Professor Reese would end up with a job, it's a nice thought that she would come to the aid of a friend so quickly. It's also nice to see her becoming friends with the neighbor children so quickly; does anyone take baked goods to welcome new neighbors anymore? The parents certainly check up on Jordie and TJ, but it's refreshing to see children given a bit of freedom and responsibility. The parents' living arrangements give them lots of opportunities to support the children, but also give the children a little wiggle room to sneak out from time to time.
The science is handled nicely; I'd definitely categorize this as science fiction rather than fantasy. Professor Reese has a job at a college that includes meetings and classes, and it's good to see a woman shown in a high level science job. In real life, she would probably have college students serving as her lab assistants, but Jordie and TJ do a good job in that role, as well as with walking Baxter.
This is somewhat reminiscent of Bunker's Felix Yz, Kade's Bot Wars, Boyce's Cosmic or Scaletta's The Winter of the Robots in that there are adventures with some scientific twists, but the inclusion of a dog as well as Professor Reese sets this off in a category all its own.
