Orange County Floor Kitchen Bath

I have carpet in my livingroom and my dog tore a couple of sections out where the carpet meets in the kitchen and that is vinly tile and there is a metal strip layed down between the livingroom and kitchen. How would I fix the tear where the damage has been done? I do not want to replace the carpet. Could I buy a little larger metal strip and tack that down between the livingroom and kitchen this is mobile home carpet. Or should I cut that section out and lay more of the same peal and stick tile down and replace the metal strip tp cover the seams where the two rooms meet? Any advice would help me. Thank you.

I just had my kitchen remodeled and I got a new laminate counter top. They put the seam right in front of the sink, which I thought was silly because it would get wet, but I guess it makes sense that there would be less seam at that point. Anyways, it was only a matter of days before it began to swell and separate. What exactly went wrong? Stupid placement? Not sealed properly? Little gnomes injecting water? Also, they failed to make the counter top level, so it is bowed near this point. Is the seam literally getting pulled apart?
