Is it alright to do some basic training inside? I am working on training my lab pup, but it has been mid 90's until 9:30 PM lately. I have an 1800 sq ft basement that is unfinished and plenty of room to do some work on heel and sit. Plus I am about to start the FF program, so I am thinking I can use this space. I just wanted to know of any drawbacks from doing this inside.
