Name change is deffiantly doable. My uncles English setter went from the name London (First owner) to, Paris (Go figure
-Second owner) ,to morgan (3rd owner), to Nipper (Uncle
) And This was over the course of4 years. She had her first name for 2 whole years and she started responding to her name within 2 weeks.
I think he'll warm up. My mom didnt want another dog either. She was and still is heartbroken oveer the death of our family (More like her) Dog. And she wasnt enthusiastic and prety much jut gave in but didnt really agree. As soon as keely came into our home. Mom loved her and Almost got jelous because i was and still am keelys favorite hoooman.. lol. He'll get over it pnce he relizes the true joy of adopting a dog in need.
