My 3-1/2yr. old Pomeranian does not like my next door neighbour's 2 yr. old Sibu Enu. When younger, we tried to get them together as we wanted them to play and thought it best to do before the Sibu Enu got to his full size. The Sibu Enu jumped on my Pomeranian and bit him a few times as this was not an uncommon practice with the Sibu Enu as he was young and very exciteable and somewhat difficult to control. (They were both on leashes at the time). Now my Pomeranian really doesn't like him. He charges at him to snap and this is the only dog that this happens with. It is sad and embarrassing as we'd hoped they get along. Any suggestions to resolve this so that they get along. The Sibu Enu now is more reserved and it's my Pom that's not friendly. Thanks!!!!!!
