I need some advice regarding a new puppy...

I’m getting a 3 month old and he’s going to be a strictly indoor dog (I say strictly indoor because I live in Tucson AZ and its too hot for a dog to be solely outdoors. I hike a lot in the mountains that are much cooler than the lower desert is and that is where I plan on spending most of my time with my dog). I saw some stuff called “No Go” something about spraying it on stuff and the dog will not go to the bathroom in that area. There is also “no chew” spray used for obvious reasons. Any thoughts on the stuff? Any advice on potty training a puppy? I’m willing for any and all input regarding puppy training. (its not that I have never trained one before, but I never did it without someone else. This will be just me and dog in my apartment and I want to do my best to make it as easy as possible for both me and the pup.)
