My pet chewed my Heating plus A/C wire

I can not feel the fact that my dog went and chewed up the wire to my central heating and cooling system! This is something that has never happened before, however now that the dog has done this I had to call the local heating and air conditioner supplier to send out a certified heat and air conditioner specialist to repair my central heating and cooling system, however by the dog chewing up the wire it has caused my central heating and cooling system to short out on me… Thus not having any heating nor air conditioner in my home.

The only solution to ensure this does not happen again would be to either put a gate around the central heating and cooling system and keep it locked up so the dog can not get inside it, then or, I just will not allow my dog to go out back and meander around, and i have not decided yet what I am going to do. But for now since the heating and air conditioner supplier repaired the wire of the central heating and cooling system I will be keeping my dog away from the backyard all together for a while until I make a final decision. The heating and cooling system is toiling superb once again and I want to keep it that way. I do not want this new wire that they installed getting disfigurementd as well! This heating and cooling system repair was a bit expensive thanks to my dog. I am not going to have to spend money twice!
