When Buster met Murphy?

I introduced Buster Bunny to Murphy my Cavalier King Charles Spaniel today, I think it went ok. Murphy REALLY wanted to get to know him, Buster didn't seem too scared and there wasn't ant fighting. Murphy wanted to lick Busters ears though, wasn't sure if I should let him though. Also wasn't sure how long to let them mingle?

Any thoughts

how sweet! my 2 met the jack russel puppy from next door through the fence the other day (not on purpose)... Jack ran for the hills and charlie sat there very still (I think he was trying to blend in. he is a bright white fluffy rabbit. it did not work).

this dog was VERY energetic though. I wouldn't reccommend introducing them to an excitable puppy but if they got along well and buster didn't seem too freaked out then why not?
