I grew up on a farm with dogs and have taken Good Citizen (behavior tng), Rally and Agility classes with my own two dogs. I also have watched and own all of the "Dog Whisperer" Training videos. My house has air conditioning. My Sheltie (mini lassie) is very friendly to other dogs. My Havanese lives with my adult daughter now and only gets dropped off occasionally if she is misbehaving (having accidents). My daughter says her behavior is always improved greatly after her stays at my house, lol. I also have a medium size dog crate if needed, I usually put my dog in our big bathroom or outside, if I have to run errands. Your dog will be taken care of very well here.
