Stopped working after 3 months.

So I got a new computer... Then I got a puppy. Less than 24 hours after bringing said puppy home, she decided to chew through said new computer's cord. No worries, I will get another. I bought this cord and it worked fine until I saw sparks because she had chewed through that cord too while I was using it. So I bought a new one and I have been very careful about said puppy being far away from new cord. It has worked brilliantly until it didn't. I went on vacation to visit family, and this cord stopped working. I get the error message that it does not have the necessary 45W needed even though it says 65W. I am going to order a different brand that will hopefully work for more than three months.
