I take Ramsey to play with my cousin year old toy poodle and they play well together. Until Ramsey gets wild and starts biting on her ears and wont let go.  They run and chase each other through the house.  

 The funny thing is Sasha (the poodle) can jump on the bed and she know Rams can't, so she will jump up there and tease him and bark at him then jump down and chase him. It is so funny and cute to watch them play!! 
 
He also plays well with my sister  Chinese Cresteds. Haven't had him around another boy so I'm not sure how he would play with one.
