I know it's only early days but we've had our gorgeous retired greyhound for three weeks now and today took him on a walk with my parents' jack Russell for the first time. They were as good as gold together, both wagging tails and sniffing and walked well together out for a walk. When we came to our enclosed garden and let them off our hound kind of mouthed my parents JR quite vigorously, I say mouthed as it didn't appear to be malicious but I found it quite worrying. The idea is that we will pet sit each for each other when we go on holiday so I would like them to get along peacefully. Does anyone have any advice on helping them to make friends calmly? I know this is only natural behaviour for my boy and I do believe he was trying to play and got carried away.
