Hi, I am after some advice. My sister has a 4 year old king charles called pebbles who is a very quiet dog who hasnt had much socialisation with other dogs. Maisy is a 4 month old beagle who when pebbles is around just wants to jump and play with her but pebbles get very aggressive and growls and snaps at her. Neither dog on thier own are aggressive but they just cant seem to get on. We tried just leaving them to sort it out themselves but Maisy ended up with a chunk of fur missing! And today my parents insisted on having Maisy shut out when we were both round visiting which I dont think is fair

. Any advice on how to help them get along better??
