8 years isn't too old to handle a rambunctious older pup! I'd reccomend a meet and greet though to see if they get along personalitywise.
I named my cat, Song. I also adopted a slightly retarded golden retriever...he has learning issues, and a funny, cute face as his head didn't develop quite right, but in some ways he's smart. His name was Rugar when I got him, but that's also the name of a handgun brand. So I renamed him HaHa, who is my favorite on the show. Just like Ha Dong Hoon, my HaHa is hilarious, and playful and at ease around everyone.Thanks! I'm glad that I decided to get him.
Stormypeak - yeah I'm a huge fan of Korean dramas. Running Man is my favorite. I love Kwang Soo and Jong Kook.
