Leading on from the thread about other dogs your one hates, does your dog have a particular friend?
Maggie generally likes other dogs, especially pubs (she's 6 months). However she's got a special friend called Albie, who we meet up the park. They instantly recognise each other and are clearly delighted to see each other and indulge in some rough and tumble play. I reckon he's her boyfriend 
. It's cute!
