We planted 4 cedars approximately a month ago and they have recently started to turn black near the base. We did a little research and it says it could be attributed to dog urine. We do own two dogs. Just curious if you could tell us what it is and how to resolve to problem. Is there a solution?

I don't think this is an issue with your dogs.
It actually appears to be a mold issue. Perhaps overwatering or poorly draining soil which could cause root rot.
Check the soil moisture levels.
