As mentioned before, all dogs are different. I have two cavaliers who are like night and day... they are fairly good friends, but not cuddle buddies, in fact... it took a long time for me to realize this, but our girl Belle actually likes her personal space and likes to sleep on her own. If she chooses to cuddle with someone, my husband is her first choice and if he is not around, I'm the runner-up! Otherwise she has her corner or her bed and doesn't budge from it, not a bother on her.
Both dogs will play together, but our boy Bobby would prefer to play fetch with one of the humans in the house! Sometimes I think they're really strange dogs, especially Belle, there are so many quirks, but probably not any more quirky than other dogs. Belle thinks she is human and Bobby knows he's a dog. Belle is quiet, calm and gentle and Bobby is barky, energetic and playful.
Anyway, I hope your dogs get more used to each other, as they will, it will just take a lot of time. I think it is GREAT that Poppy is Barney's ears, that's a big plus!
