Baby name = Dog name😩

So my husband and I are pretty close with his brother-in-law's family. They went to school together, work at the same company (brother-in-law's father owns it), spend summers at their cottage, and so on. Well just now I found out that the name we (Lydia) chose provided we have a daughter is the name of their new dog!!! 
Who names their dog Lydia? Would you still use it? I'm heartbroken. 😕
